Anyone ever had success with any fish or chemical to kill off Xenia? I've got a massive infestation in one of my tanks. I've done the manual removal route and H2O2, but these are only temporary fixes as it always comes back with a vengeance! Only inhabitants in the tank are a couple clowns, goby, and 15 RBTAs. There are some random zoas, mushrooms, rics, and leathers that I don't mind losing as long as the xenia goes with it.... Just looking at options that don't involve me removing the rocks and bleaching (it's one large cemented structure).
