Have you tried Reef Flux ? It cleared GHS and Bryopsis up in just a few days. It worked great for me.So I have hermits, and I bought some mexican turbo snails and some nassarius snails, but my hermits just ate them! I have the hermits, one big nassarius snail and a couple other smaller snails. I have a emerald crab and also a peppermint shrimp. Like I said, my hermits kill any snails I add. I have these corals glued down on the rock so idk how to get them off to take the rock out and scrub them without killing them?
