Looks like a winner so far. I have a Deltec AP702 that's doing a good job with the current bio load: 4 Tangs, a pair of Japanese Swallowtails, Saddleback Butterfly and a pair of Anthias. Problems.............the thing sucks in so much air that I have to shoot fresh water down the valves daily to keep them clean and clear to run effectively and the Aquabee pump is getting harder to find when it breaks.
