I have a 90 Cichlid tank - 1 Ocscar, 2 Severums, 2 Rainbow, 1Mosaic Gar, 1 Leaf Eater, 1 Lima Shovel Nose and 1 Royal Pleco. All are 4-6 inches. I plan to upgrade soon. I currently filtering a an XP3. I have a Magnum 350 and was wondering if I use it as well or would it be too much filtration. Amonia, Nitrate and Ph are good.
