To start with, you have got to make positive you've got the budget for this upgrade. Everything can want to be bigger -- not only your tank but the heater, the filter, the substrate layer, the lighting, and in fact the plants and fish you may populate your tank with. You also need a sturdy piece of furniture to put your tank on. Tanks this large often have a footprint of half dozen feet by a pair of feet or a lot of (at more than two feet in height); and, as a result of water weighs 8.35 pounds per gallon, your table must be in a position in-tuned one,670 pounds (758 kilograms) in water, plus the load of the tank itself, the filter and alternative equipment, and whatever substrate, rocks, plants, and fish you set inside the tank. The table might be your biggest expense!

In choosing a tank, your first choice can be between glass and acrylic. Most enthusiasts prefer glass, as a result of glass is a lot of additional tough to scratch than acrylic; glass additionally maintains its clarity (some varieties of acrylic can yellow with age), and glass is cheaper. However, acrylic is less distorting, will be molded into a variety of shapes, is lighter in weight, and is a lot of immune to shocks: a sharp impact can scratch the acrylic but is unlikely to shatter it, whereas glass could crack or shatter. Unless you would like a VERY large tank (say, 500 gallons), or need a tank in an odd shape or with bowed sides, then glass is most usually the better choice.

As for substrate, you'll be able to quickly calculate the amount you may want to hide the bottom of your tank at a median depth of two inches. Multiply the aquarium's length by its width (in inches), then divide by ten. The resulting variety is the quantity of pounds of gravel you may need. Therefore, if your tank is seventy two x twenty four inches, seventy two times twenty four equals one,728; divided by 10, you'll need 172 pounds of gravel. (If you are using another substance for your substrate layer, then you will need to work out the weight relative to the weight of gravel to use this formula.)

Smaller aquarium tanks are higher suited for freshwater environments only, however a bigger tank will easily accommodate a saltwater atmosphere also; you'll want to think about a reef tank, that will enable you to prominently display live corals and different marine invertebrates, as well as fish that play a job in maintaining a coral reef ecosystem.

The same 200-gallon tank, whether or not glass or acrylic, will hold either salt water or fresh water, but you would like to decide on a filter carefully. There are three primary kinds of filter: biological (that, using bacteria, converts ammonia into nitrate; mechanical (which physically removes each dissolved and particulate material from the water because it passes through); and chemical (that removes toxins through chemical reaction or absorption). Any of these systems will work with salt water as well as contemporary water, however you need to confirm sufficient circulation through your filter for your massive tank. If you have got salt water, the whole volume of water in your tank should "turn over" (go through the filter) a minimum of five times each hour. For a 200-gallon tank, therefore, the filter should be capable of turning over 1,000 gallons of water every hour. (For fresh water, the turnover rate will be slightly less, however a minimum of three times per hour.)

Your aquarium heater, conjointly, should have sufficient capability to maintain the correct temperature throughout your tank; as a easy rule of thumb, you need 5 watts of heating power for every gallon of water. So if you wish to heat your 200-gallon tank approximately ten degrees above average area temperature, you will need as abundant as 1,000 watts of capacity total. It's best to induce two heaters at 500 watts each and place them at opposite ends of the tank. Be positive to consult with your dealer; if you're planning a reef tank that requires a higher water temperature, for instance, you'll need more heating power.

The foremost common quite aquarium heater is an immersible heater, that hangs on the aspect of the tank, sitting partially in the water with the controls above the water line. These are comparatively low-price, however are plainly visible. Absolutely submersible heaters will be a lot of simply hidden from view, but they're pricier and higher fitted to smaller tanks. Substrate heaters are positioned beneath the substrate layer, and are effective at promoting plant growth and heating the water uniformly. Filter heaters reside at intervals the filter, again hiding the heater from view.

Another piece of apparatus you will want to contemplate may be a powerhead: a submersible water pump that produces a unidirectional current. Powerheads are excellent for freshwater tanks housing river fish, as they can approximate river currents. They are also appropriate for saltwater reef tanks, where underwater turbulence helps promote reef growth. For a reef tank, purchase 2 or more oscillating powerheads and place them in several locations, creating competing, multidirectional currents.

Once you have got a basic idea concerning the equipment you'll need, you can then decide what kind of underwater ecosystem you wish to create in your massive tank. Your choice might determine exactly what kind of filter you wish, or how powerful your heater wants to be, thus consult rigorously along with your dealer in choosing your hardware.
