I found out my 3 month old DT 120 gal tank has ick already (yes my fault for going to fast . I do have a 12 month bio cube that I want to use as a hospital tank. It has live rock and inverts . My plan is to ditch the live rock because of the GHA on it and transfere the inverts over to the DT and put all fish in bio cube coper dose bio cube and go 76 day fallow on DT . Questions I have , will the GHA transfere over from the snails and crabs ? Should I take out the substrate in the bio cube ,i have a cho chip star and a long spine urchin to transfere over to DT so snails and crabs. And one large long tencale anomie. Just kin d of a big move double guess need so advice be nice to me.
