This section provides an overview of the equipment used to run and maintain an aquarium. We have also included a guide to the hard decor used to furnish our aquariums and listed information on some other items which may prove useful to the hobbyist.
Plants also play a part in the aquarium in terms of aquarium decoration and more importantly, making the fish feel at home. Articles on choosing and caring for aquatic plants are therefore also included here.
- Tank – Tanks come in many different sizes and shapes, and are most commonly made of glass. Aquariums also can be made of acrylic, fiberglass, plywood, and concrete.
- Filtration System – Filtration systems in saltwater aquariums usually consist of a pump, and a trickle filter with bioballs. A trickle filter is an acrylic water reservoir with a series of bioballs, and a fiberfloss filter. The water pump transfers water from the reservoir into the tank, and an overflow siphon brings new water from the tank and trickles it over the biospheres before it collects back in the reservoir.
- Heater – Many overlook the importance of an aquarium heater. Fish are very sensative to temperature fluctuation, and can suffer from stress, which can result in sickness, due to temperature changes. An aquarium heater basically regulates the temperature of the water in the aquarium to keep it within a degree or two of the temperature setting. Heaters generally come in two designs: the type which clips onto the back rim of the tank, and extends into the water, and the fully submersible unit.
- Light Source – Light sources for saltwater tanks vary greatly. Depending on the type of inhabitants in the tank, different Spectrums and intensities are required. Generally, the best light sources are custom built (they are cheaper), and consist of a series of different bulbs. If you are not sure exactly what spectrum is best, a full spectrum bulb, supplemented with an actinic blue bulb will usually provide sufficient spectrum and will create a nice effect int he tank for visual purposes.
- Hydrometer – Salinity in the saltwater aquarium is measured by Specific Gravity (S.G.). Specific gravity is basically a ratio of the density of a substance to the density of distilled water. A hydrometer reads the specific gravity of the saltwater. By using a hydrometer, one can accurately maintain the salinity of the aquarium, which is rather important in a saltwater system. The desirable range of specific gravity for a saltwater aquarium is 1.020 to 1.026 S.G., which is about 28 to 35 ppt.(parts per thousand)
- Substrates – The substance which most saltwater aquarium owners choose to be the foundation for their aquarium is crushed coral. In addition, silica sand, dolomite, coral sand, shell hash, pea rock, river gravel, terrestrial rock, and live rock can be used.
- Gravel Vacuum – Gravel vacuums are very simple, yet useful devices. When doing a water change for the aquarium, gravel vacuums are used to remove both particulate residues and nitrates which accumulate in the bottom of the tank over time. At the same time, they remove water from the tank, allowing for a quick water change. Usually they consist of a thin vinyl tube, with a slightly larger diameter plastic attachment which you sweep over the bottom of the aquarium. The word “vacuum” comes from the fact that these devices function by using a siphoning effect.
- Test Kit – Unless the owner of the fish store you buy your aquarium from is extremely nice, you will have to pay for any water test of your aquarium. These are done to check the pH, ammonia, nitrite, and nitrate levels in your aquarium. For more information on what these compounds are, check the saltwater biological cycle page. This can be rather cheap, but occasionally, there will be times when one needs to check it periodically, and costs can add up quickly. Besides, it is much more convenient to be able to do your own water test, and you won’t have to go half way across town to find out that your tank is not ready for another fish yet. These kits vary from the extremely complex the rather simple. Ask the fish store owner which kit he or she recommends.
- Protein Skimmer – A protein skimmer is not a necessity for a saltwater aquarium, but if one has the money to invest in one, it will prove to be very useful. Protein skimmers range in price from around $100 to about $300. Organic material and other proteins accumulate in an aquarium over time from various sources, and eventually biologically decompose into nitrites and other toxic substances. Protein skimmers are used to remove the organics before they biologically decompose. They work using a very simple phenomenon. By using the hydrophilic and hydrophobic nature of organic materials, a protein skimmer removes organics from the saltwater by passing small bubbles through the water, causing the organics to congregate in a foam. This foam is then removed.
Caring for Your Aquarium Equipment
This is rather an easy process to do. First locate and remember where all your filter pads are. Next, shut off all your pumps. (Yes, your fish will be fine while you do this)
You do not have to shut off circulation pumps until you are ready to clean them.
Now remove all the filter pads or one at a time. It does not matter which way you want to do it. Using RO water begin to rinse and ring out the filter pads.
Remember to check the pads every once a month to make sure they are staying strong. If they appear to be limp or you just can’t get them to come clean replace them.
Keep an eye on your pads for muck build up and do a cleaning no less then a 2 to 3 months apart or as you notice that the water is having a hard time getting through the filter pad. Overflow pads can build up quickly as this is your first defense of ridding your tank of large objects. Once everything is back in place don’t forget to start your system up again.
Overflow pipes should be check about every 6 months to make sure that the algae build up is not to thick to cut off the water going through to your sump or back in to your tank. This is simple and easy and some people clean them, but I find that it is just as easy to replace them. This will however depend on your tank setup.
If you are one that would like to clean them, then a simple vinegar wash with a non-copper brush should do the trick. But again depending how long your hoses are will depend on whether this will work for you.
Pumps will become encrusted over time and to avoid a burn out you can clean these as well. Again this is going back to the vinegar cleaning. Most pumps will come apart so that the blades can be cleaned. (Refer to the user manual of your pump). Once open brush all parts with a vinegar solutions and rinse or use the pump in RO water to remove any extra vinegar.
