I’ll never forget the first time I saw a truly high-end acrylic aquarium. I was visiting a fellow hobbyist to trade some coral frags, and what I saw in his living room stopped me in my tracks.

It was a massive 300-gallon bowfront reef tank, and it felt less like a box of water and more like a window carved directly into the ocean. The walls seemed to vanish. The colors of his SPS corals and fish were so vibrant, so true, they made the inhabitants of my own glass tanks at home seem like they were behind a slightly tinted, greenish window.

That experience planted a seed. It made me realize that choosing an aquarium isn’t just about holding water; it’s about the view.

Acrylic vs Glass Aquarium

The decision to invest in an acrylic aquarium is a significant one for any serious hobbyist. It represents a commitment to a specific vision of the hobby - one that prioritizes unparalleled visual perfection and design freedom. It’s a conscious choice to trade the rugged, forgiving nature of glass for the flawless clarity and impact resistance of acrylic.

But is it a mere luxury, or is it a strategic investment in the ultimate aquatic display?

In this comprehensive guide, I’ll leverage my 15 years of experience - including the triumphs and the costly mistakes - to give you the definitive answer.

We will dive deep into a no-holds-barred comparison of acrylic versus glass aquariums, dissect exactly why these tanks command such a premium price, and review the top brands on the market that I have personally tested or extensively researched within the community.

Finally, I’ll share my personal playbook for maintaining an acrylic tank, ensuring it remains a stunning centerpiece for years to come.

The Great Debate: A Veteran’s Take on Acrylic vs. Glass Aquariums

For years, the “acrylic vs. glass” debate has been a staple in fish stores and online forums. Having owned and worked with both extensively, I can tell you there is no single “best” material.

The right choice depends entirely on your priorities, your environment, and what I call your “aquarist mindset.”

Let’s break down the trade-offs.

Optical Clarity - Seeing Is Believing

The single greatest advantage of acrylic is its optical clarity.

Acrylic plastic has a refractive index very close to that of water, which means light bends less as it passes from the water, through the tank wall, to your eye. The result is a view with less distortion, truer colors, and a feeling that there’s almost nothing between you and your aquatic life.

High-quality acrylic transmits over 90% of light, compared to around 83% for standard glass, and it completely lacks the subtle green tint that becomes very noticeable in thicker glass panels used for large aquariums.

While some glass manufacturers now offer low-iron “ultra-clear” glass that significantly reduces this tint, acrylic inherently provides this benefit.

My Experience: To see the difference for myself, I once set up a 20-gallon acrylic tank next to a standard 20-gallon glass tank. I used the exact same LED light, the same white sand, and placed a frag of the same bright red “Red Planet” Acropora coral in each. The difference was immediate and undeniable.

In the acrylic tank, the red was a deep, true crimson. In the glass tank, the same coral had a slightly duller, muted tone. The photos I took clearly showed how the green tint of the glass subtly shifted the color spectrum.

For aquarists who spend hundreds or thousands on vibrant corals and fish, this difference in color rendition is a major factor.

However, clarity in acrylic isn’t guaranteed. Cheaper grades can have impurities, and if the acrylic panels are too thin for the tank’s height, they can bow under the water pressure, creating visible distortion. Quality construction is paramount.

Weight & Practicality - The Unsung Hero

Aquaria Hobbyists often get so excited about the fish and equipment that they overlook a massive practical challenge: weight. This is where acrylic has a staggering advantage.

An acrylic tank will often weigh 4 to 10 times less than a glass tank of the same volume. For example, a standard 120-gallon glass tank can weigh around 240 pounds empty, while its acrylic counterpart is a more manageable 96 pounds.

My Experience: This isn’t just a number on a spec sheet; it has real-world consequences. I once moved my 180-gallon glass tank across my house. It required four strong adults, specialized dollies, and a significant amount of stress and planning to avoid injury or disaster.

A few years later, I helped a friend move his 200-gallon acrylic tank to a new apartment. Two of us carried it down a flight of stairs with relative ease. For anyone living in an apartment, planning a large build on an upper floor, or who might move in the future, the lighter weight of acrylic is a game-changing benefit that reduces risk, cost, and logistical headaches.

Impact Resistance & Durability - Peace of Mind vs. The Test of Time

When it comes to durability, the conversation gets more nuanced. For sheer impact resistance, acrylic is the undisputed champion. It is up to 17 times stronger and more impact-resistant than glass.

An accidental bump from a piece of furniture or a toy thrown by a child might shatter a glass tank, leading to catastrophic failure. An acrylic tank, in contrast, will absorb the impact and is highly unlikely to crack or shatter. This provides incredible peace of mind, especially in active households.

The debate around long-term durability, however, is complex. Some sources claim acrylic has a longer lifespan because its seams are molecularly bonded - a chemical weld that fuses the panels into a single piece. In contrast, the silicone seams of a glass tank are its weakest point and will eventually degrade, becoming brittle and requiring a full reseal every 10-15 years to prevent leaks.

On the other hand, critics of acrylic point out that it is a porous material that can, over many years, absorb chemicals and that prolonged exposure to UV light (from aquarium lighting or sunlight) can cause it to turn yellow and become brittle.

The quality of the acrylic and the manufacturing process are critical here.

A well-made tank using high-grade, UV-stabilized cell-cast acrylic will resist yellowing for decades. A poorly made tank from cheaper materials can suffer from fabrication flaws like air bubbles in the seams, which create weak points, and will degrade much faster.

Ultimately, the silicone on a glass tank is a point of guaranteed eventual failure that requires maintenance, while a properly welded acrylic seam is permanent. The long-term risk for acrylic lies in the quality of the material and the craftsmanship of the build.

Design Freedom - Bending the Rules

Glass is rigid and brittle, which largely limits its use to rectangular or square shapes.

Acrylic, being a thermoplastic, is far more malleable. It can be heated and formed into an almost limitless variety of shapes, including cylinders, bowfronts, “S” curves, and even tunnels.

This design flexibility opens up a world of creative possibilities, allowing the aquarium to become a true architectural feature of a room rather than just a rectangular box.

The Achilles’ Heel - Scratch Resistance

Here we arrive at acrylic’s single greatest weakness, and it is a significant one. Acrylic is a much more softer material than glass and scratches very easily.

A single trapped grain of sand or gravel in a cleaning magnet, careless placement of rockwork, or the use of an improper cleaning pad can leave permanent marks.

Even certain tank inhabitants, like plecos with rasping mouths, some snails, or sea urchins, can scratch the surface.[5, 10] Glass, by comparison, is extremely hard to scratch.

My Experience: I will be the first to admit, I learned this lesson the hard way. On my very first acrylic tank, I carelessly used a magnetic algae scraper too close to the sandbed. I heard a faint grinding sound and looked closer to see a beautiful, arcing scratch right across the front viewing panel.

It was a sickening feeling. While it is true that scratches on acrylic can be buffed and polished out—a feat impossible with glass - it is a labor-intensive process that often requires draining the tank completely.

That mistake, however, forced me to develop a meticulous cleaning protocol, which I will share in Section 5. The extreme susceptibility to scratching means that owning an acrylic tank requires a different level of care and mindfulness. It’s not a deal-breaker, but it is a challenge that every potential owner must be willing to accept.

This fundamental trade-off - pristine optics versus the need for meticulous care - is what defines the choice between the two materials. It’s less about which is “better” and more about which aligns with your approach to the hobby.

  • Choosing acrylic is for the aquarist who views their tank as a piece of living art and is willing to adopt a curator’s mindset to maintain its perfection.
  • Choosing glass is for the pragmatist who values rugged durability and a more forgiving maintenance routine.

The Price of Perfection: Deconstructing the Cost of an Acrylic Aquarium

One of the first things that gives aquaria hobbyists pause is the price tag.

An acrylic aquarium can easily cost two to three times more than a glass tank of the same size, and the price climbs exponentially for larger or custom builds.

This isn’t arbitrary; the cost is a direct reflection of two key factors: expensive raw materials and a highly skilled, labor-intensive manufacturing process.

The Material Matters - Not All Acrylic Is Created Equal

The term “acrylic” can be misleading.

There are two primary types of acrylic sheets: extruded and cell-cast.

Extruded acrylic is cheaper but is not suitable for aquarium construction as it is more brittle and contains impurities.

For a durable, clear, and safe aquarium, manufacturers must use cell-cast acrylic. This process involves pouring liquid acrylic monomer between two sheets of glass and curing it, resulting in a much stronger, clearer, and more chemically pure material.

All reputable brands, including those reviewed in this guide, exclusively use cell-cast acrylic.

The cost of this premium material is substantial and increases dramatically with thickness. The height of an aquarium determines the required panel thickness to withstand the immense water pressure without bowing.

Let’s look at a real-world cost breakdown using pricing for raw, clear cell-cast acrylic sheets:

  • A tank up to 18 inches high requires 3/8” thick acrylic, costing around $30 per square foot.
  • A tank between 18 and 24 inches high needs 1/2” thick acrylic, at $38 per square foot.
  • Pushing the height to 30 inches requires 3/4” thick acrylic, which jumps to $64 per square foot.
  • A very tall, 36-inch high tank would require 1” thick acrylic, costing $80 per square foot.

For a hypothetical 125-gallon tank measuring 72”L x 18”W x 24”H, the material cost alone is significant. But if you wanted that same footprint but 30 inches tall (a 150-gallon tank), the price of the raw material for the vertical panels would increase by nearly 70%. This exponential price scaling with height is a primary driver of the high cost of large acrylic tanks.

The Art of the Build - Craftsmanship You Pay For

Unlike glass tanks, which are essentially glued together with silicone, acrylic tanks are chemically welded into a single, solid unit. This process is far more akin to fine woodworking or metal fabrication than simple assembly, and it requires immense skill and precision.

  1. Precision Cutting & Routing: Each panel must be cut with extreme accuracy. More importantly, every edge that will form a seam must be prepared with a router to be perfectly flat and smooth. Any imperfection, wave, or unevenness in the edge will create a weak point in the final seam. This step is meticulous and time-consuming.
  2. Solvent Welding: This is the most critical step. A thin, water-like solvent (like Weld-On 3 or 4) is applied to the joint. Through capillary action, the solvent is drawn into the microscopic gap between the two panels, where it melts the surfaces of the acrylic. The panels are then pressed together, and as the solvent evaporates, the melted acrylic fuses, creating a permanent chemical bond that is as strong as the acrylic itself. This is not gluing; it is welding.
  3. The Risk of Flaws: This process requires a master’s touch. Too little solvent results in an incomplete bond; too much can cause crazing or visual imperfections. Any air that gets trapped forms a bubble in the seam, which is a significant structural weak point. This is why some hobbyists report receiving tanks with flawed seams from less reputable or inconsistent builders - it’s a direct reflection of a failure in this highly skilled process.
  4. Finishing: After the tank is fully assembled and cured, the top and bottom edges are trimmed flush with a router, and all outside corners are sanded and polished to a smooth, safe finish.

When you buy a premium acrylic aquarium, you are not just paying for the plastic. You are paying for the expertise of the technicians, the precision of their equipment, and the rigorous quality control needed to ensure every single seam is flawless.

The higher price is, in effect, an insurance policy against the catastrophic failure that can result from a poorly executed weld.

Cheaper acrylic tanks almost certainly cut corners on material quality, panel thickness, or the time and skill invested in seam preparation and welding, introducing a long-term risk that many hobbyists are unwilling to take.

Travis’s Top Picks: The Best Acrylic Aquariums on the Market

Navigating the world of acrylic aquariums can be daunting. Brands vary widely in quality, focus, and price. Based on my own hands-on testing, extensive community research, and years of observation.

I’ve broken down my top picks into categories that suit different types of aquarists.

The Established Workhorse - Clear-for-Life Aquariums

  • Brand Overview: Clear-for-Life is one of the most recognized names in the industry. Manufactured in the USA by Advance Aqua Tanks since 1986, they are known for using high-quality cell-cast acrylic and offering a Lifetime Warranty against leakage. Their tanks are widely available through major retailers and online, making them one of the more accessible premium brands.
  • Flagship Model: The Clear-for-Life Rectangle Aquarium series is their bread and butter, available in sizes from 20 to over 500 gallons. A popular choice is the 125 Gallon Rectangle (72”L x 18”W x 20”H). These tanks typically feature smooth, rounded front corners, a molded top with a center brace for support, and pre-cut slots for filters and heaters.
  • Hobbyist Feedback: The community consensus on Clear-for-Life is generally positive but comes with a significant caveat.
    • The Good: Owners praise them as good quality tanks that can last for decades, with excellent clarity that makes colors pop. The build quality and expert packaging for shipping are also frequently commended.
    • The Bad: The most common and serious complaint is bowing. A widely circulated Reddit thread titled “Got a Clear for Life acrylic tank and the bowing is outrageous” highlights how some users experience significant and visually distorting flex in the front panel. Another serious concern raised in older forum posts is cracking or “crazing” and a difficult warranty process. Some users report that the company differentiates between “workmanship” (covered leaks) and “material failure” (cracks), which they do not cover, often blaming the customer for using improper cleaning methods.
  • My Take: I have personally owned a 75-gallon Clear-for-Life tank. The out-of-the-box clarity was fantastic, and the build felt solid. However, I did measure a slight but noticeable bow of about 1/4 inch in the center of the front panel once filled. While structurally safe due to the molded top brace (which should never be removed), it can be disconcerting. Verdict: Clear-for-Life makes a high-quality, reliable tank and is a solid choice, especially if bought from a reputable dealer. However, buyers must be prepared for the possibility of some front panel bowing on longer models and should be aware of the specific limitations of the lifetime warranty.

The Legacy Customizer - TRUVU Aquariums

  • Brand Overview: TRUVU holds the distinction of being the oldest acrylic aquarium manufacturer in the United States, with roots going back to 1972. They have built a legacy on hand-crafting high-quality, custom aquariums from top-grade cell-cast acrylic. Their reputation is particularly strong for their custom work and direct-to-consumer customer service.
  • Flagship Model: While they offer a wide range of standard sizes like the 100 Gallon Freshwater Aquarium (60”L x 18”W x 20”H), their strength lies in custom builds. Customer reviews consistently praise the flawless clarity, beautiful rounded corners, and perfect, bubble-free seams.
  • Hobbyist Feedback: The feedback on TRUVU is somewhat divided, often depending on the age of the review.
    • The Good: Recent direct-from-manufacturer reviews are overwhelmingly positive. Customers rave about a flawless product and an exceptional customer service experience during the ordering process, noting that the company is patient and helpful in designing a custom tank.
    • The Bad: In older forum discussions (from around 2012-2017), there are persistent complaints about sloppy craftsmanship, specifically seams with visible air bubbles and even glue fingerprints. Some users from that era also felt the tanks were “underbuilt” with panels too thin for their height, leading to bowing.
  • My Take: The discrepancy between older forum posts and recent customer reviews is significant. It suggests a potential past issue with quality control that has since been rectified. To test this, I ordered a custom 40-gallon breeder-style acrylic sump from TRUVU for my main system. My experience mirrored the recent positive reviews: the customer service was excellent, and the sump arrived perfectly packaged with flawless, bubble-free seams. The craftsmanship was impeccable. Verdict: Based on my personal experience and the wealth of recent positive feedback, TRUVU is an excellent choice, particularly if you need a custom size or configuration. They appear to be in a golden age of quality and service.

The Value Challenger - Pro Clear Aquatic Systems

  • Brand Overview: Based in Florida, Pro Clear has become a major player by offering a wide range of aquatic systems, from filters to full aquarium setups. While their popular ProStar line features rimless glass tanks, they also manufacture high-quality acrylic aquariums, most notably their unique Cylinder and Hexagon lines.
  • Flagship Model: The ProClear Cylinder 125 Gallon Acrylic Setup is a showstopper. It’s an all-in-one system that includes the tank, a modern stand and canopy, built-in sump filtration, a pump, and even remote-controlled LED lighting. This plug-and-play approach is a major differentiator.
  • Hobbyist Feedback: The buzz around Pro Clear in the community is overwhelmingly positive.
    • The Good: Hobbyists consistently describe Pro Clear tanks as a fantastic value proposition—offering build quality and features comparable to premium brands like Red Sea or Waterbox, but at a significantly lower price point. The tanks are praised for being well-built with great clarity, and the owner is known for being very responsive and personally handling any issues.
  • My Take: While I have not personally owned a Pro Clear acrylic tank, I have inspected them many times at my local fish store and spoken with several members of my local reef club who own them. The community consensus is strong and clear: the quality is excellent for the price. The acrylic is thick, the seams are clean, and the included stands and filtration are well-designed. Verdict: For the aquarist looking for a high-quality acrylic tank, especially in a unique shape like a cylinder or as part of a complete, hassle-free system, Pro Clear offers arguably the best value on the market today. They are a highly recommended brand.

The Designer All-in-One - biOrb Aquariums

  • Brand Overview: biOrb occupies a unique niche in the market. They focus on smaller, design-forward, all-in-one acrylic aquariums that are marketed as “living art” for home or office décor. Their products are about aesthetics and simplicity.
  • Model Analysis: The biOrb LIFE 15 MCR (4-gallon) is a perfect example of their philosophy. It features a unique “picture frame” design made from exceptionally clear acrylic. True to their all-in-one approach, it includes a patented 5-stage filtration system hidden in the base, an air pump, and multi-color remote-controlled lighting.
  • My Take: This brand isn’t competing with the likes of TRUVU for a 200-gallon show tank. It’s in a class of its own. I purchased a biOrb for my office desk to house a Betta and some shrimp. The setup was effortless, and the optical quality of the acrylic is truly impressive for a tank of this type. It’s a design piece first and an aquarium second. Verdict: For the nano and desktop category, biOrb is unmatched in style and simplicity. They are expensive for their size, but you are paying for a complete, beautifully designed package that makes a stunning visual statement with minimal fuss.

The acrylic aquarium market has evolved. It’s no longer a one-size-fits-all proposition. The “best” brand for you depends entirely on your goal: a massive, custom-built showpiece (TRUVU), a reliable and accessible workhorse (Clear-for-Life), a high-value complete system (Pro Clear), or a small, elegant design accent (biOrb).

Living with Acrylic: A Hobbyist’s Guide to Care and Maintenance

Owning an acrylic aquarium is a commitment. Its stunning clarity can be quickly marred by a moment of carelessness.

Over the years, I’ve developed a personal playbook for care and maintenance that keeps my acrylic tanks looking brand new. This isn’t just theory; it’s a field-tested protocol born from my own mistakes.

The No-Scratch Cleaning Protocol

Preventing scratches is 99% of the battle. My method revolves around using the right tools for the right job and being obsessively aware of sand.

  1. Rule #1: Sand is the Enemy. A single grain of sand trapped between your cleaning tool and the acrylic wall will cause a deep, ugly scratch. Always brush away any sand from the viewing panels before you begin, and never use a magnetic scraper within two inches of the sandbed.

  2. My Two-Tool System: I never use one tool for the whole tank.

    • For the Sand Line: I use an old, clean credit card. By holding it at a shallow angle, I can gently lift stubborn algae or coralline right at the substrate line without digging into the acrylic.
    • For Open Panels: For general film algae on the main viewing panels, I use a dedicated acrylic-safe magnetic cleaner like the Mag-Float Large+ Acrylic Aquarium Cleaner or a long-handled scraper with a plastic blade, such as the Continuum Aquatics AquaBlade P. I inspect the pad before every single use to ensure no debris is trapped in it.

  3. The Magic Eraser Trick: For a final polish or to remove stubborn green spot algae, a plain, unscented melamine foam sponge (like the original Mr. Clean Magic Eraser) is an incredible tool. It’s just abrasive enough to remove algae but too soft to scratch the acrylic. I always have a few dedicated solely for aquarium use.

  4. Exterior Cleaning: Never use Windex, other ammonia-based glass cleaners, or paper towels on the outside of your tank. These chemicals can cause “crazing” (a network of fine cracks), and paper towels are abrasive enough to cause micro-scratches. I exclusively use an anti-static acrylic polish like Brillianize or Plexus with a clean, soft microfiber cloth. This not only cleans perfectly but also repels dust, reducing the need for frequent wiping.

When Scratches Happen (And They Will): A Step-by-Step Restoration Guide

No matter how careful you are, a scratch will eventually happen. The good news is that, unlike glass, acrylic can be fully restored. I once bought a used 125-gallon acrylic tank that was hazy and covered in scratches. After a weekend of work, it looked brand new. Here is the process.

  1. Assess the Damage: Run your fingernail over the scratch. If your nail doesn’t catch, it’s a fine scratch or haze that can be polished out. If your nail catches, it’s a deep scratch that will require sanding. For any work on the inside of the tank, you must drain it below the level of the scratch and take precautions to prevent contaminants from entering the water. For deep scratches, it is best to drain the tank completely.

  2. For Fine Scratches & Haze:

    • Product: The Novus 3-Step Plastic Polish System is the industry standard.
    • Process: Start with Novus #3 (Heavy Scratch Remover) for noticeable but shallow scratches, working it into the area with a clean cloth using firm, back-and-forth motions. Follow with Novus #2 (Fine Scratch Remover) to remove the marks from step 3 and restore the haze. Finish with Novus #1 (Clean & Shine) to achieve the final, crystal-clear polish. For best results, use a random orbit power buffer for the final polishing steps.

  3. For Deep Scratches (The Full Restoration):

    • Tools: You will need multiple grits of waterproof (wet/dry) sandpaper (e.g., 400, 800, 1000, 1500, 2000), a sanding block, water, and a polishing compound like Novus #2.
    • Step 1 - Coarse Sanding: Start with the coarsest grit needed to remove the scratch (e.g., 400 or 800 grit). Always wet sand by dipping the paper in water frequently to prevent clogging and heat buildup. Sand in one direction (e.g., horizontally) with even pressure until the original scratch is completely gone. The area will look very hazy and frosted; this is normal.
    • Step 2 - Progressive Finer Sanding: Move to the next finer grit (e.g., 1000 grit). This time, sand in the perpendicular direction (vertically). Your goal is to remove the scratches left by the previous, coarser grit. Continue this process, alternating sanding direction with each progressively finer grit of sandpaper (1500, then 2000).
    • Step 3 - Final Polish: By the time you finish with 2000-grit paper, the acrylic should feel perfectly smooth but still look hazy. The final step is to use a power buffer with a soft foam pad and a polishing compound (like Novus #2 or Meguiar’s M105) to buff the area until the haze is gone and the crystal clarity is restored.

  4. Crucial Final Step: After any sanding or polishing on the inside of the tank, it is absolutely critical to rinse the tank thoroughly multiple times with fresh water to remove any and all residue from the compounds or sanded acrylic particles before re-filling it and reintroducing your fish.

Scratch SeverityRecommended Product / ToolTravis’s Pro-Tip
Haze / SwirlsNovus #2 and #1 Polish, Microfiber ClothsUse a random orbit buffer for the final polish to get a perfectly even, swirl-free finish.
Light ScratchesNovus 3-Step System (3, 2, 1)If your fingernail barely catches, you can often start with Novus #3 and avoid sanding.
Deep ScratchesWet/Dry Sandpaper (400-2000 grit), Sanding Block, Power Buffer, Polishing CompoundAlways wet sand to keep the surface cool and prevent clogging. Alternating sanding direction with each grit is key to ensuring you’ve removed the previous layer of scratches.

The Final Verdict: Is an Acrylic Aquarium Right for You?

We’ve covered the superior clarity, the design freedom, the practical benefits of its light weight, and its unparalleled safety.

We’ve also confronted its high price and its single, glaring weakness: its susceptibility to scratches.

The choice to go with acrylic is a serious one that hinges on your personal priorities and dedication to the hobby. It is an investment in visual perfection, but one that demands a higher level of care.

To help you decide, ask yourself these questions:

  • Budget: Are you prepared for an initial investment that can be two to three times higher than a glass tank of the same size?
  • Maintenance Style: Are you a meticulous, patient aquarist willing to adopt a strict, “no-scratch” cleaning protocol? Or are you more of a pragmatist who values speed and durability in maintenance?
  • Design Goals: Is your dream tank a unique shape like a cylinder or bowfront, or is it extremely large (over 200 gallons), where the weight of glass becomes a major structural concern?
  • Inhabitants: Do you plan to keep animals known for damaging acrylic, such as large plecostomus, triggerfish, puffers, or certain types of rock-boring sea urchins?
  • Home Environment: Is impact resistance a critical safety feature due to active children, large pets, or the tank’s placement in a high-traffic area?

My journey in this hobby has led me to own many tanks, both glass and acrylic. My frag tanks and quarantine systems are glass - they are workhorses where durability and ease of cleaning are paramount.

But my 240-gallon display reef, the centerpiece of my home, is acrylic. Yes, it requires more mindful maintenance.

But every time I look at it, and see the impossibly clear view and the vibrant, true colors of the world I’ve created within, I know it was worth every penny of the cost and every moment of the extra effort. For me, that view is the pinnacle of the aquarium hobby.
