So the ich in my tank is not getting better (see post from a couple weeks ago). I'm going to do hypo in my dt this week and needed some help. Here's my plan : tank all liverock and corals out and put them in a couple tanks, take out all the crabs, snails, and 2 sand sifting stars and put them with the rock. I'll have lights and power head in with the rocks. So now ill have fish and sand in the dt and ill go through the hypo process. I was thinking since i will be keeping the rock and corals out for 12 weeks that I would just do hypo for that long as over kill. Now for the answers I need. I will be running my protein skimmer so should I go buy a filter or just put carbon in mesh bags and place them in the sump for filtration? Will the crabs, snails, and stars carry the ich and just bring it back to the tank after I put them back in after 12 weeks? What should I do with the sand bed, keep it in, replace it after hypo, or just take it out all together ad put new sand in after the ich is gone? The sandbed is old anyway so Idk. Please help
