I feel for you! - I have had Ich as well come and go - not much fun at all. I use MEDIC from Polyp Labs - reef safe and typically a 10 day cycle I believe. DIDO above, feeding well is very crucial - feed a lot, seems to keep the stress low. the Medic is a powder - add at night and early AM. I soak my food in Selcon, crush up real garlic(soak food in this - feed as well) I use a Ginger powder as well. I do use Dr.G's Anti Parasitic caviar - some fish eat it some do not, it has medication in it as well. You can soak you algae sheets with Selcon, the product shown is SELCO and the other is SELCON.
