So, if your fish do have ick (also called whitespot) the fungus/antibiotic meds are not going to help at all, and may put extra stress on them. Whitespot is a parasite. My advice is stop doing meds, raise your temp (I've done all the way to 88F) and do WC every day if you can or every other day. Make sure you also vacuum the gravel. The WC and vacuum are going to remove the parasites from your tank and are going to be the best bet for removing the parasite. I would also read up on the disease to make sure it's actually what you're dealing with.
