Cleaning your tank during a showing of ICH

[Frenchie2]

My blue tang used to get ich from time to time. I feed my fish a variety of foods - frozen, pellets, noori, etc. I serve frozen foods with a few drops of Garlic Xtreme and Selcon every other day. For pellets, I give them "Biofish Food" from Dr. Bassleer's - those pellets work so good. I give them pellet food every other day too. Those pellets contain a tiny bit of cooper but will not endanger your invertebres. I have 4 shrimps ( & a whole lot of corals) and they eat it all no problem and are healthy. Since I've added the pellets to their diet, I've never seen any ich on any of the fish at all for the last year. I do 20% water change everyweek, religiously.
If you can't find those pellets at your LFS, J&L sells them. Good luck!
