A cloudy fish tank that looks white or milky, is usually caused by a bacteria bloom. This is usually the most common type of cloudy fish tank water. This can happen if even one time a lot of extra food was dumped into the fish tank or through regular over feedings. Other causes could be if a fish died and wasn’t removed from the aquarium or if your fish tank is still cycling. Depending on what is causing the cloudy water, there are different things to do that can fix it. First, you need to correct the cause, so if you have been over feeding fish or if there is a fish that died, the problem should first be corrected so the water doesn’t continue being cloudy after you clear it up.
Everyone loves a nice clean fish tank, but sometimes your perfectly clean tank can become a cloudy water mess. In order to return your tank back to its former glory, you first have to understand the causes of a cloudy fish tank. There are three different water colors of cloudy fish tanks and each have their own causes. Depending on the type of cloudy water you have, there are different things you can do to help clear the water up. Whatever the cause may be, you must first correct the cause before you can keep your water clear.
A cloudy fish tank that is green in color is typically caused by an algae bloom. This is different than the algae that grows on the glass of your fish tank, this is specifically algae that grows in the water column. Green cloudy water from algae is usually caused by excess nutrients in your fish tank or too much light on your fish tank. Both of these causes have easy fixes that can help clear your water quickly. Excess nutrients are caused by either, overfeeding, overstocking, or poor maintenance. Overfeeding is easily corrected by reducing the food you feed your fish. Overstocking is a little trickier, but essentially you need to remove some fish and either give them to a friend or give it back to the fish store. Poor maintenance is corrected through performing to remove the excess nutrients.
No matter what type of cloudy water you have, usually water changes are the best way to clear the water. There are different chemicals that you can use to help clear the water, but in my opinion water changes are your best weapon. Some people have also used UV Sterilizers to keep water from becoming cloudy, while these work very well, they may not be practical for everyone and could potentially mask the underlying problem. The best way to clear your cloudy fish tank is to first determine the cause, and then correct it.
