Water gets cloudy if you overfeed your fish, if your tank is overstocked and if your filter system is not working properly. Replace 1/3 to 1/2 of the water in the tank Remove any excess dirt and mulch from the bottom of the tank, do not feed your fish for 2 or three days and when you feed them again feed only as much as they will eat in one minute. If any food sinks to the floor, you are feeding too much. Clean your filter , and if you do not have one, get one suitable for the size of your aquarium.
