I'll have to change this review if it works appropriately after the second use. I used reviews to decide how much to use since I only have a 39 gallon tank. This stuff unfortunately won't treat fish unless they actually ingest it. So, if you have a fish that hasn't been eating, this isn't going to work. It seems to have gotten rid of all of the callamus worms in the fish that actually ingested the meds that I soaked into brine shrimp. I had one death and I think that's only because that fish had the worms so badly that her intestines were probably way too chewed up. This didn't effect my shrimp and I even found some snails in the tank that it had no effect on. I gave my tank food treated with it for 3 days and on the first day treated the water with it as well. Hopefully with my next use it will get rid of these pests completely. Waiting for my non-eating fish to die and I will treat again.<br /><br />Update: this did not work for the callamus worms
