Fish just came down with ich in my 125 gal im using heat treatment trying to get the temp to 88 degrees f. Its not a huge problem yet only two fish have it but ik its probably settled on the substrate waiting to infect others. Current temp is 86 degrees. I have scaleless catfish some synodontis and cories so salt treatment is out of the question i would say right. Should i just crank the temp to 89 to kill the parasite that way.
