This treatment does not treat/kill worms, round worms, flat worms, tape worms, or any other type of worm. I believe that I already mentioned that earlier in this thread.
Treatment with feed containing 3% Epsom salts (magnesium sulphate; Atoma Canada, Montreal, Quebec) (30 g Epsom salts per 1000 g of feed) was administered to 4 of the 17 tanks of fish for 2 consecutive days. The fish were fed at a rate of 2% body weight (BW) per day.
