What Causes Cloudy Water In Fish Tanks – The Signs

There are many possible causes of cloudy water in a fish tank. It could come from something as simple as new unclean decorations added to the tank or it could be as complicated as a chemical imbalance and even bacteria blooming.

A sure sign of a bacteria bloom is when your water is milky and has a very bad odor.  Not all bacteria are bad but some bacteria blooms can be deadly to your fish. When the nutrient levels get extremely high they go ballistic. This can be what causes cloudy water in fish tanks.

One concern you may want to consider when trying to figure out what causes cloudy water in fish tanks is whether or not the fish are being overfed.  This can also cause cloudy water. Check the bottom of the tank for leftover food.

If you are not changing the water on a regular schedule, your water can also become cloudy.  You can check your pH with a test kit. If the pH reads 6.0 or lower, you should change the water immediately.  A pH of 6.0 or lower is bad for both an open or closed style tank.

What Causes Cloudy Water In Fish Tanks – Different Tanks

What causes cloudy water in fish tanks with open or semi-open style tanks? Many times these style of tanks could possibly have a stopped up filter causing  debris to cloud up your water.

If you are still not sure what causes cloudy water in fish tanks don’t rush. As long as your water doesn’t seem extremely bad and your fish are acting fine, give it a little time.  Sometimes if bacteria is the cause the bacteria will kill its self. 

This is definitely not advice for all cases. If you are concerned about your fish you should probably remove them until you get your problem under control. It is extremely helpful to have a quarantine tank just for occasions such as these. Regular maintenance will also help you enjoy your fish tank without concern.
