While many aquatic hobbyists agree that owning an aquarium is a worthwhile and rewarding venture, just as many would concede that there can be several fish tank problems-both in the set-up and in the long-term maintenance. It's a good idea before owning a fish tank to be aware of these disadvantages and to know what issues to look out for.
For starters, because of the sheer weight and magnitude of many indoor aquariums (some weighing more than 800 pounds and up), there is always the likelihood that fish tank problems may arise from someone bumping into, cracking or otherwise breaking the tank. The first problem with this is the most obvious: the loss or damage to your tank, decorations, and (of course) your fish and other aquatic life. But another danger to be aware of is the electrical hazard this can present. With several electrical sources usually right nearby or within the tank-including the pump, heater and lighting-knocking over or splashing an aquarium, especially a large one, can make for some huge fish tank problems.
Along these same lines comes the problem of homemade or makeshift aquarium stands. Unless you have significant expertise in woodworking or metal construction, it's always the best idea to purchase a manufacturer designed and crafted tank stand. Commercially available units are designed to stand up to the consistent weight and stress invoked by aquariums. Do yourself a favor and purchase one from a company (don't make one yourself) and you'll be sure to avoid the stand breaking, which is one of the most common fish tank problems.
Likewise, make sure (especially if you have a large tank , such as 40 gallons and above) that you are putting the tank and stand on a surface that can support the weight of the unit. In some cases, you may need the help of an engineer or professional builder to ensure its safety. Generally speaking, however, it's best to put your tank along a wall or near some other type of structural support. Putting the tank in the middle of a room not only puts it at risk of being knocked into, but also risks that the floor won't be able to support its weight.
Another issue that happens quite frequently is putting the aquarium too near a window or other place where sunlight shines into the tank. While you may think that it looks nice at first, the sunlight will heat up the tank and not only put the fish and other marine life at risk, but will also promote the growth of algae. Pretty soon your beautiful, clear fish tank will be covered in thick, green slime. If you don't have an alternative but to put the tank where it will get some sun, invest in an ultraviolet sterilizer to neutralize algae growth.
All in all, you can avoid many common fish tank problems entirely with the set-up and design process.
