Hey, you know the wet/dry filter or whatever kind it is thats in the back of nano cube aquarium systems? well, mine`s messed up. according to the best lfs guy, I overfilled the filter. all of the three compartments in the back are just about filled up. my lfs dude said that i should just siphon water out of the compartment with the pump, but when I did, the water in the tank went down too. when I add water to the tank, the filter fills back up. the reason I didn`t know about this before was because I bought it second hand, without the owner`s manual. what`s a guy to do?
