High-Temperature and Salt Treatment

We started treat Pearl and Midnight with this traditional method that recommended by some experts. The reason why we use this method is that we don't want to pollute the aquarium with too much chemical. IckGuard leaves stains which I don't like. So far, they looked okay. Pearl is a little weak. She's not so active. Midnight is very active and seems to be stronger. I have to keep the high-temperature and salt for 10 days to eliminate Ick completely. I'll see if this approach works for me.
