I've got all of my algae problems taken care of a couple months ago, but now I'm dealing with cloudy water. Not green, I took care of the green cloud algae. Not white so I don't think it's a bacterial bloom. It's more like sediment that the filter won't remove. I'm using a fluval 304 with the output flowing into an old HOB filter (this cuts down on the current in the tank). The bottom basket in the canister is filled with poly wool and so is the HOB filter. In the upper two baskets in the canister is BioMax. After going through the foam, then the poly wool twice, I would think that even the smallest particles would be removed. The intake hose is on one end of the tank and the return is at the opposite. I just want my crystal clear water back, any help is appreciated!! Thanx
