I have a relatively new 75gal freshwater tank with juvinile african cichlids. Originally I had just an Aquaclear 110 HOB and the water was crystal clear (one of THE most important things to me). Knowing that I'd need extra filtration as these guys grow, I picked up a Marineland C-360 canister filter on a black friday special. Since installing it a couple weeks ago, the water is no longer crystal clear. It's just...pretty clear. There's a faint white haze in the water I can't seem to get rid of. Any ideas how I can restore the crystaline water clarity??
