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.

When buying an aquarium for either a freshwater or marine environment, you've got several choices to create relating to filtration, heating, lighting, substrate, and after all the fish and other aquatic life you would like to stock your tank with. However, even the form of your tank will have an impact on your eventual aquarium atmosphere, not solely in overall visual impact however in the standard of life of your fish.

Most common aquarium tanks are rectangular (for larger tanks) or bowl-formed (for tiny tanks). However, tanks these days return during a large choice of shapes, including bow-front, corner bow-front, cylinder and 0.5-cylinder, hexagon and pentagon, cube, bullet, and various specialty shapes. While rectangular, bow-front, and cube tanks will be made of glass furthermore acrylic, other shapes like cylinders are typically created of acrylic by custom manufacturers.

Glass is tough to scratch, however a pointy impact might crack or perhaps shatter glass. Acrylic, on the opposite hand, can scratch easily, but is a lot of difficult to crack or shatter. Glass maintains its clarity but refracts light-weight and therefore distorts pictures and colors; acrylic is less refractive, but could yellow with age, so losing clarity. Glass is denser and heavier, and supports its own weight; acrylic needs a stand that can support the entire bottom surface of the tank. And acrylic is on the market in a wider selection of shapes. Keep these differences in mind when choosing between glass and acrylic -- and whether or not glass tanks are on the market in the shape you prefer.

Contemplate how much cubic volume you need for every fish you propose to purchase. Any tank you buy should state the quantity of water it will contain; in fact, with a rectangular or cubic tank, it’s simple to calculate this yourself. For little, freshwater fish, you will would like a minimum of one gallon of water for every in. of fish (measuring the fish lengthwise). Marine fish require more. Therefore no matter the form of your tank, ensure that you’re providing enough water to sustain your fish population.

Totally different tank shapes have different footprints -- the footprint being the world of the underside of the tank. The footprint defines the horizontal living area of your fish, and a few fish want more of it. Cichlids, for example, need more area to determine territory, in rocks and other features you put in in your tank. You shouldn’t crowd them.

The peak of a tank -- the vertical area -- also varies from tank to tank. Usually, tanks with more vertical space have smaller footprints; i.e., they are not as long or wide. While this may create a dramatic visual effect, your fish can not have as much space to swim. Particularly if your tank is slender -- if there’s very little house from front to back -- your fish will be forced to swim forwards and backwards in straight lines, with very little area to dart about and create broad turns. Some wall-mounted tanks are notably narrow. All fish want to swim, some more than others; if you prohibit their space, whether lengthwise or depthwise, your fish will be sad and even unhealthy. One exception is angelfish: as a result of of their size and swimming patterns, angelfish do well in tall, slim tanks.

Tall tanks are also detrimental to plant life in your tank substrate; it’s harder for light to penetrate to the increased depth, and your plants may suffer. If you've got a tall tank, create sure your substrate plants don’t want a lot of sunshine, or provide extra tank lighting.

And verify your surface space -- the realm at the high of your tank, at the water’s surface. For many tanks, the surface area can be admire the footprint, but for odd-shaped tanks, which may not be the case. The surface of your tank is where gas exchange happens: carbon dioxide is released from the water in exchange for oxygen. This process is facilitated after you add an air stone to your tank, when you put in filters and powerheads, and in general once you produce surface agitation. Fish require well-oxygenated water, and a minimized surface area will hinder this process. If you have solely a few fish, this may not be a drawback, except for larger fish populations, guarantee that you have got adequate surface area.

There are more sensible issues when selecting the form of your aquarium tank. Deep tanks -- tanks with bigger height -- can be more durable to clean. Suppose concerning how straightforward it can be to reach your arm right down to the underside of your tank, for cleaning or redecorating. This could appear sort of a minor concern, however over time an inaccessible tank could influence be a major annoyance. What kind of available space do you have got for your tank -- does one already recognize where you’re going to put it? Depending on what kind of aquatic setting you wish to form, your house may not be adequate; be prepared to purchase a replacement stand if required.

And the way easy can or not it's to view your fish? As mentioned on top of, glass tends to be more refractive, and distorting, than acrylic. Odd shapes can additionally be distorting -- bow fronts, hexagons, pentagons, and cylinders may look lovely at initial, however viewing from certain angles can create distortions that don’t occur with flat-walled rectangular tanks. If viewing your fish without distortion is very important to you, then a flat-walled tank is most suitable.

If you bear these points in mind, you will purchase the tank shape that’s most suitable for your purposes.

If you are first fixing a freshwater or marine aquarium, probabilities are you're thinking most about the animal life you're eager to stay there -- whether or not fish or some kind of invertebrate life. Watching fish swimming around, interacting with every alternative and with different life forms, is one among the largest attractions of having an aquarium, and indeed a lot of of how we tend to founded an aquarium depends on the kinds of fish and other animal life we tend to wish to raise. But, some thought ought to additionally go into layout matters -- creating the surroundings for your fish and alternative animal life. This involves everything from your substrate material to rocks, display ornaments, and plant life. And indeed your alternative of plants can play a massive role in determining your filtration, lighting, heating and different hardware matters.

For freshwater tanks, gravel is the most well-liked substrate material. Sand is another risk, though sand compacts tightly, and it may be troublesome for your plants to spread their root systems. If you like the look of sand, you would possibly consider a twin-layer substrate, with sand on the prime (concerning two inches in thickness) and a bottom layer that is wealthy in nutrients and looser in structure, allowing your plants' root systems to grown.

Vermiculate, that may be a mixture of aluminum, iron, and magnesium, is an ideal choice. You'll be able to also combine the vermiculate layer with another compound such as laterite, which could be a porous, weathered clay; laterite has high concentrations of iron oxide, and holds nutrients that plants require.

For saltwater systems, notably reef tanks, crushed coral may make a good substrate choice. Crushed coral will continue to unharness calcium carbonate into your tank, that can promote new growth in your coral. Crushed coral will also facilitate your tank water maintain a high pH level, needed by marine fish. Aragonite is another chance; this compound is stuffed with helpful bacteria and different organisms, and is wealthy in calcium carbonate as well.

As for planting your aquarium, your selections are endless. The layout of aquatic gardens has become an art kind, and international competitions are held for the foremost innovative designs. You are solely limited by your imagination, but there are some pointers to keep in mind.

Most tank layouts are designed with a foreground, middle ground, and background in mind; if you're planting many sorts of plants, the tallest plants should generally be in the background and also the shortest in the foreground. As your plants grow, some trimming might be necessary to keep the overall style in balance -- simply like you have to prune bushes in front of your house. Stem plants tend to grow quickly and create higher background plants; ferns, on the opposite hand, are slow growers, taking a long time to become dense.

The center ground ties the background and foreground together; here, you'd be most likely to position rocks and driftwood plus selected plants. Stem plants are generally not applicable here; keep those in the back. Varied rosette plants will be appropriate for your middle ground; ferns and alternative plants that like to connect themselves to rocks and driftwood will conjointly work in this area. Seek for slow growers. You'll be able to maintain ferns and rosette plants by trimming back massive leaves and pruning runners, if they are growing toward areas where you do not need the plant to spread. One easy fern to plant is that the java fern; you can wedge its roots into a crack in some driftwood, and it will gradually begin to proliferate.

Low-lying plants within the foreground can want the most frequent trimming; if you wish a lot of of a coffee-maintenance tank, you can leave the foreground further from plants and layer your substrate with a lightweight-coloured, natural-looking cosmetic sand.

Marine reef tanks present entirely totally different sorts of challenges, as a result of the point of interest of your tank can be rock formations and coral rather than green plants, though you'll be able to add lots of green plants moreover to add beauty and interest to your tank layout. As you first lay in your substrate material -- whether or not sand or crushed coral -- you may also want to lay in "live rock": straightforward rock (primarily calcium carbonate) that contains many styles of micro- and macroscopic marine life. Your coral can be anchored to live rock, which conjointly serves as a biological filter for your marine tank. The live rock pieces can lie directly on top of your substrate, or higher, directly on the bottom surface of the tank, therefore that it becomes partially buried by the substrate. This means, any burrowing creatures won't be ready to dislodge the rock and something growing on it.

Do not overdo it with live rock, and don't stack the rock items on high of each alternative; one general guideline is to position around 1.thirty five to 1.five pounds of live rock for each gallon of water in your aquarium.

You may presumably build your reef toward the center of your tank, permitting for sufficient water flow round the reef also through any canyons or tunnels you build in. You will want to consider the fish and mobile invertebrates, also immobile invertebrates, that you plan to position in your tank. Several marine fish are aggressive; even if you've got already set on a suitable mix of fish that may get usually get along, a number of these fish may want caves or hiding places, therefore be positive to build in masses of nooks and crannies. And invertebrates that tend to cool down in one place, like ocean anemones, need adequate current passing by however not direct current, which could be too strong. Thus if you intend to buy ocean anemones, be positive to build in adequate area for them.

There are various issues in laying out your aquarium design, however with careful forethought and designing, you'll be able to build a stunning aquarium atmosphere that will offer you pleasure for years.
