Recently purchased a 54 gal bowfront that was drilled for an overflow,magnum350 canister filter, 60lbs live rock& coral substrate. Someone told me that the canister was not intended for the overflow style tank and that a sump was needed. Been running the tank for 5 week and introduced some fish at the 3rd week. Everything is alive and all levels are great. Want to use the amircle 75 pro to do the right job with a 700gph pump. Reading the site it tells me most people think the bios balls are a bust. I am totally new and go to 2 different fish people in the area to get opinons and that is all I get. I need some help. I now have a cleaner shrimp, a little cleaner on the bottom, Butterfly,Angel, and 3 small fish. How does one get right answers?
