The way that i ahve always done it is turn the heat up to 85-86 degress and add one table spoon per 10 gallons. Is this the heat and salt method that you guys use????
For detailed instruction on treating ick check out the ick article linked below.
Using heat AND salt together to treat ick:
2-3 Tablespoons per five gallons of water. (Salt is sodium chloride--plain table salt without any additives. The Aquarium Salt that can be purchased in most fish stores will work fine. Dissolve the salt first and add it gradually over several hours time)
80-82 degrees. (At these slightly raised temps the life cycle of the parasite is speeded up so that the salt and other meds can be effective.)
Using either salt alone or heat alone to treat ick:
4-5 tablespoons per five gallons
86+ (Heat raised this high is suppose to outright destroy the parasite BUT because water holds less O2 at higher temps some fish have a bad reaction to heat being raised this high. I think you're better off doing the combination of heat and salt rather than heat alone)
Treatment must continue for a minimum of ten days and then for at least three days after you see the last white spot.
Its important to start any ick treatment with a large partial water change and gravel siphoning. This will help to reduce the overall numbers of ick parasite in your tank.
