My 210 gallon tank recently had an outbreak of ick. I have taken out the carbon from the filter and used an ick medicine. I have also raised the temperature of the tank. Yesterday we did a 30% water change and vacuumed the tank because the fish looked like they were getting better. Our catfish had the ick the worst but he seems to be doing a little better. Our black pacu looks as if he is shedding white stuff (almost skin like). The ick before was just small white spots so I am not sure if this is something else. The ammonia levels in the tank are good. I don't know what else to do at this point so anything would help.
