Thanks again to everyone. The tank is in about its 5th day of treatment and all visable signs of Ich are gone. The only fish ever affected was my Angel Ram I had recently purchased. None of my other fish ever had any spots on them. I am using the salt/heat method as recommended and it seems to have done the trick. I know I should keep the heat up for at least a week but after that can I start lowering it down to around 76 degrees? It is at 84 degrees right now. I was worried about the White Cloud Mountain Minnows as they like cooler water but they seem fine. Also, when can I start running carbon again. Again thanks to all. I have had my 55 gallon for about 3 years and had never experienced any disease before so I was clueless so I appreciate the knowledge and patience.
