Why is a fish aquarium cloudy?
Cloudy water in an aquarium can be a sign that an essential element for a healthy aquarium isn’t functioning properly. The situation should be examined to see if something requires immediate attention.High pHAquarium water with a high pH appears grayish and dull. It is extremely dangerous to fish and other aquatic life because it is filled with ammonia, and it should be treated immediately.Algae BloomsAlgae appears in the form of a greenish cloud or grows along aquarium surfaces and sides. It should be treated or controlled when it is first noticed because it will quickly overgrow a tank and fill its water with unhealthy amounts of oxygen and ammonia if it begins to die.Waste BuildupIf an aquarium is not properly filtered or is overpopulated, or if its fish are overfed, then bacteria and waste will build up quickly and cause the water to appear brownish and cloudy. Filtration will help to get rid of the cloudiness, and cutting back on feeding and being careful not to fill the aquarium
