Hi. There are many products for ich control in the market. However, it may help to understand the life cycle of the organism. The ich that we see on the fish are mature and we can't kill them without killing the fish. After a few days, these will fall off to the bottom of the tank, multiply and then swarm back up to attack the fish in even greater numbers. The cycle completes itself from a few to several days depending on the water temperature. We raise the temperature to speed up the life cycle of ich and the organism sort of "burns itself". It is when the ich falls to the bottom that we can break its life cycle by removing the spores or cysts by siphoning the bottom of the tank 3x a day. A bare bottom tank would be best to use for this procedure. Then, the use of proprietary remedies will be more effective. Hope this helps. Good luck.
