So one of my platy's has ick again. Last time i treated with a medicine and it took over 2 weeks to go away and only ended when the last fish with ick died, I treated with the medicine for the next 5 days or so. I've heard a lot of talk about turning the temperature up and adding aquarium salt. What's the exact process for doing this? I have platy's, molly's, and a pair of gourami's, are they all ok with salt. I also have some medicine left over should I use that too?
