having a huge problem!! I've got a bad case of ick in one of my tanks so i added aquarium salt Copper Sulfate and raised the temp in the tank to 88. The ick is only affecting the loaches badly but some of the other fish have it too. The other fish in the tank seem to be getting a little better but the loaches are getting worse. I have lost 3 loaches of the 5 in the tank already... any suggestions on how to remedy this?
