i have a 55 gallon tank with 2 bio wheel 350 penquin filters and i set the tank up with black sand artificial plants and a huge piece of a root from the bottom of a stream the tank stayed crystal clear for about to weeks and one morning i woke up it was really white and cloudy doe anyone know why it would do that all of the sudden thanks

With the limited information you have given, I would say it is a bacterial bloom. Common with a tank that is still cycling. It will clear when the nitrogen cycle has completed.

what else do u need to know

How old is the set up? Do you have fish in the tank? What are the water parameters, ie ph, ammonia, nitrite and nitrate? How are you testing the water and lastly what is your maintenance schedule?? I think that should do :-)

i got four cichlids and a oscar i recently just put the black sand and the different piece of driftwood dont know the ph or anything and the setup is a few months old since i changed those to things

Cloudiness is pretty typical of a new tank. Probably bacteria bloom.

No way to test the water?

Agreed - cloudiness usually happens in a new tank.... you have no test kit to test the ammonia, nitrites, nitrates, pH?
