Hey guys So I have a 30 gallon cube Refugium/sump/skimmer Kessil lighting Parameters pretty good other than the occasional high nitrate (not outrageously high). But the other day I came home to my snowflake clown being eaten by my hermits and snails So I didn't know what could have got him being I only have a pair of clowns and a potters angel and a small dottyback. So a day later I found white spots all over the other clown and then some on the Angel. Obviously ich, so today my clownfish was stuck to the side of my vortech mp10, dead (yeah I know, sucks :/ ) So I'm left with a angel and a dottyback I don't have a quarantine tank, but my question is, how do you rid your tank of ich if there's Not fish in it, but you do have a ton of coral (which I'm fully stocked, and the corals are glued down) which I'm not ready to take apart especially if there's no fish. Will the ich parasite die with no fish to live in within a certain amount of months etc.? I'm perfectly fine not having any fish for quite some time. Does ich attack shrimp, snails, crabs etc? Any info please help
