I have a 65 gal hex tank. It has about 30 fish in it of mixed species. Over the past couple weeks ive noticed alot of debris floating around. I have a aqua top CF-400UV canister filter cleaning the tank. Ive changed the carbon, the fine pad mesh, added more mesh,added more carbon. cleaned the canister multiple times. I do 10-15 percent water changes once a week. However the debris never seems to go away. The day after i replace the filter media its clean but within 24 hours even before feeding, all the debris is back.
Any idea on how to keep this thing clean?
