I have a 55 gal Cichlid tank that just won't clear up. I think since i've had it, a little over a month, it's been clear twice. Once at the very beginning and maybe a couple weeks ago. Now it's cloudy and stays that way. Is that common for a Cichlid tank? Or is my filter just not handling it. I have a Top Fin filter that is rated up to 60gal. I have a couple lava rocks and some decorations with fake plants and gravel. Tried the water clear stuff and it only made it worse. Any thoughts or help would be much appreciated. Oh and I've been doing PWC's anyway because my nitrite levels are still on the high side.
