I used heat and salt to cure ich as recommended by many users here on AC and it worked! I have a well-stocked and well-planted tank. I lightly vacuumed the tank first with a 30% water change adding a mix of 1 tsp per gallon of salt (for the entire tank) to the replacement water. I gradually increased the heat from 79 to 87 degrees over a three day period, I also added a little more salt during water changes (every other day), until I reached an equivalency of just under 2 tsp per gallon. In the first two days the ich got worse, but over the course of 5 days it was gone. The important thing is to maintain the heat and salt for one week after all signs of ich have disappeared. I did a light vacuum of the gravel during water changes. After the week of sustained treatment, I then began lowering the temperature 2 degrees a day and did water changes every other day with no salt added. The Ich has not returned. I have three Clown Loach, two Polka Dot Loach, eighteen Neons, etc. with no losses. The only plants effected were my Crypts.
Good Luck!
