Can anyone give me some info on this protein skimmer. It came with some other equipment i bought and am not sure if its going to be good enough for my setup. Also i have a a 6 foot T5 lighting system with 4 bulbs all on a single reflector. My tank is around 21-22" deep. Can anyone give me an idea of what what kind of corals i can keep. I'm looking to just keep softies so i'm hoping its good enough for that. Thanks a lot!
