I have a 55 gal with penguin 330 and a ugf. I recently turned off the UGF with an eventual intention of removing it. that filtration setup worked well for over a year for my Tiger Barb community. then my tigers started dropping like flies. I figured out that the chinese algea eaters murdered them all, my fault not enough algae in the tank. So now I have decided to try cichlids. I have unhooked the ugf and powerheads attached. Is the penguin 330 suffecient enough filtering for 1 juvenile Green Terror (growing fast about 2-2.5") a pictus cat 5", 1 striped raphael 6" and 2 chinese algae eaters.
