So I'm about to start hyposalinity on my 225 gallon display tank to treat ich. I would do a hospital tank but I got about 15 fish which include emperor, yellow tang, porcupine puffer, foxface, dwarf angels, gobies and damsels. So I'm wondering what I should be expecting, is the ammonia or nitrate gonna rise over the course of the whole treatment? Do I turn the protein skimmer off?
