I just wanted to know if there was such a thing as too much filtration? I have a 55 gallon tank with 2 oscars, 4 cichlids, and a pleco. Also I have 4 live plants. I was using a penguin 330 with the dual biowheels and a friend gave me another penguin 330. Its now filtering 660 gph. Could this be harmful? In addition, I still have the fluval 2 internal filter moving water below the surface at a rate of 60gph. I was just a lil unsure of what to do now. I just added the 3rd filter about an hour ago and will take a look at the water conditions tomorrow morning. Any thoughts?
