I try to keep it simple, each tank has double sock sumps(berlin), uroreef skimmers(big ones)and 1/2 horse power chillers, 4 400 watts and 72in atinics vho's dual,(just 2 400 watts over half round)tunzees,maxsi jets 1200's,lots of live rock, and hand dose b-ionic because reactors to me are headaches with several reeftanks.the 175 bowfront and the 144 half circle are substrate free.I clean all filters and skimmers and glass everyday even if there not durty. Persistence pays off.
