Upgrading to a Higher Capability Aquarium
If you've been raising aquarium fish for a few years already and fancy the hobby but find that your tank's capacity is limiting what you want do, it might be time to upgrade to a bigger capacity. Though two hundred-gallon tanks are not counseled for beginners, they provide limitless options for an experienced hobbyist who has the time, and the creativity, to construct a gorgeous display.
To start with, you've got to form positive you have got the budget for this upgrade. Everything can want to be bigger -- not solely your tank but the heater, the filter, the substrate layer, the lighting, and after all the plants and fish you'll populate your tank with. You furthermore mght need a durable piece of furniture to position your tank on. Tanks this huge typically have a footprint of half-dozen feet by two feet or additional (at additional than 2 feet in height); and, as a result of water weighs 8.thirty five pounds per gallon, your table must be in a position in-tuned 1,670 pounds (758 kilograms) in water, plus the load of the tank itself, the filter and alternative equipment, and no matter substrate, rocks, plants, and fish you place within the tank. The table could be your biggest expense!
In choosing a tank, your 1st alternative will be between glass and acrylic. Most enthusiasts prefer glass, as a result of glass is a lot of a lot of troublesome to scratch than acrylic; glass additionally maintains its clarity (some sorts of acrylic can yellow with age), and glass is cheaper. However, acrylic is less distorting, will be molded into a selection of shapes, is lighter in weight, and is additional proof against shocks: a sharp impact can scratch the acrylic but is unlikely to shatter it, whereas glass may crack or shatter. Unless you wish a VERY giant tank (say, 500 gallons), or wish a tank in an odd shape or with bowed sides, then glass is most often the better choice.
As for substrate, you'll be able to quickly calculate the amount you may would like to hide the bottom of your tank at a mean depth of two inches. Multiply the aquarium's length by its width (in inches), then divide by ten. The ensuing number is the quantity of pounds of gravel you will need. Thus, if your tank is 72 x 24 inches, 72 times twenty four equals 1,728; divided by 10, you may want 172 pounds of gravel. (If you're using another substance for your substrate layer, then you may would like to see the burden relative to the load of gravel to use this formula.)
Smaller aquarium tanks are higher fitted to freshwater environments only, however a larger tank can simply accommodate a saltwater setting likewise; you will wish to think about a reef tank, which will enable you to prominently display live corals and alternative marine invertebrates, furthermore fish that play a task in maintaining a coral reef ecosystem.
The identical two hundred-gallon tank, whether or not glass or acrylic, will hold either salt water or fresh water, but you wish to settle on a filter carefully. There are three primary kinds of filter: biological (which, using bacteria, converts ammonia into nitrate; mechanical (which physically removes both dissolved and particulate material from the water because it passes through); and chemical (that removes toxins through chemical reaction or absorption). Any of those systems can work with salt water with fresh water, but you would like to confirm sufficient circulation through your filter for your massive tank. If you've got salt water, the whole volume of water in your tank ought to "flip over" (meet up with the filter) a minimum of 5 times every hour. For a two hundred-gallon tank, therefore, the filter ought to be capable of turning over 1,000 gallons of water each hour. (For contemporary water, the turnover rate will be slightly less, but at least three times per hour.)
Your aquarium heater, conjointly, should have sufficient capacity to take care of the right temperature throughout your tank; as a straightforward guideline, you would like five watts of heating power for each gallon of water. So if you wish to heat your 200-gallon tank approximately 10 degrees on top of average area temperature, you'll need as a lot of as one,000 watts of capacity total. It's best to urge 2 heaters at five hundred watts every and place them at opposite ends of the tank. Be positive to consult with your dealer; if you're coming up with a reef tank that requires a better water temperature, for instance, you'll would like a lot of heating power.
The foremost common reasonably aquarium heater is an immersible heater, which hangs on the side of the tank, sitting partially within the water with the controls on top of the water line. These are relatively low-price, however are plainly visible. Totally submersible heaters can be a lot of easily hidden from read, but they are 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, once more hiding the heater from view.
Another piece of kit you will want to think about could be a powerhead: a submersible water pump that produces a unidirectional current. Powerheads are good for freshwater tanks housing river fish, as they'll approximate river currents. They're conjointly appropriate for saltwater reef tanks, where underwater turbulence helps promote reef growth. For a reef tank, purchase 2 or a lot of oscillating powerheads and place them in several locations, creating competing, multidirectional currents.
Once you have got a basic idea about the equipment you'll would like, you can then decide how much underwater ecosystem you would like to form in your massive tank. Your choice could verify precisely how much filter you wish, or how powerful your heater desires to be, thus consult rigorously along with your dealer in choosing your hardware.
