why does my fish tank water look cloudy

When the water in your aquarium turns cloudy and your beloved fish disappear into a hazy fog it is easy to get frustrated. Sometimes the reasons why your tank went from fish heaven to fish apocalypse may be as clouded as the tank water itself. Rest assured, tank water does not change so drastically without reason. This means you probably did something wrong. But it also means that, once you understand your mistake, you can change your tank management practices and greatly reduce the chances of it happening again. In this article you will read about five common reasons fish tanks turn cloudy.


One or several of these causes may be at the root of what has happened to your tank. In many cases these problems are easy to solve, and if you act soon enough your fish should pull through without any trouble. Throughout this article you will see two pieces of advice repeated no matter the cause of your cloudy water. First, you need to perform a partial water change. This will dilute the dissolved chemicals and waste in the water and make it a safer environment for your fish. While it may be tempting to remove all or most of the water in an attempt to clear things up, this can potentially make things worse.


A 25% water change is a good starting point. Second, use a gravel vacuum to clean the gravel and remove as much of the fish waste and decaying matter as possible. When this junk is left to accumulate on the substrate it can eventually cause tank-wide issues. With most of the good vacuum systems you can change the water and clean the gravel at the same time. and gravel vacuuming are two of the most important duties of your aquarium care routine. However, there are often other factors that can make your tank water turn cloudy, and unless you eliminate the problem it is likely to occur again.


As you will see, some of the issues that cause an aquarium to turn murky are symptoms of greater problems.
Treat with a chemical filter. Chemical filters usually take the form of granules or pellets. The chemical filter is normally placed sequentially after an existing mechanical filter and the waterвor between the mechanical filter, and biological filter. Follow the instructions on the product you select, but normally, you will simply pour the instructed amount of granules into the filter, or pre-fabricated filter bag for placing in the tank water directly.


A form of activated carbon is typical choice in this case. Activated carbon absorbs organic particles, medications, bacteria causing odors, and colors dissolved into the aquarium water. When the water is becoming cloudy, or smells bad, it is time to change the chemical filter. Usually, these filters are good for 1-2 months. If you use a filter bag, then put the bag in a high water-flow area of the tank.
