Hi All, New to the forums and to a bigger fish tank. I have a 50 gallon tank with a Penn Plax Cascade 700. It's been running since May, so about 3 months. There about 5 plants in there, along with about 60% stock. I've changed out the floss pads twice, and this last time I changed out the carbon and floss pads and it seems the tank has gone into a mini-bloom cycle; cloudy water and now dissipating. My filter has: Lower tray: Floss Pad then Marineland Activated Carbon with Ammonia Neutralizing Crystals Upper Tray: Floss Pad then Coarse pad On top of that tray: Bio Sponge Everything has checked out fine #s wise, but the tank was getting some particles floating around, hence the reason I decided to change out the 3 pieces of media? Is what I'm doing wrong? Any tips?
