thanks. I have Ich in my tank too. believe or not theres a good percent of us have ich, just doesnt always find a host thats all. I tried "reef safe" meds & hypo for 10 weeks or more. still got them on a Powder Brown Tang. this i believe in to keep it in control:
quarantine
garlic/selcom
uv
for a cure: hyposal is the way to go if you have fish & inverts.my shrimps,snails & crabs survived it.
