If you want to manage it then I agree with the above of reducing stressors and providing stability. But to “get rid” of it you need to remove and treat fish then take the DT fallow. Understanding the life cycle of ich helps understand why the treatment plans are what they are.You can help the fish kick it by reducing stress and elevated temps help speed the parasite life cycle along. Reducing stress comes in many forms, effective feeding with quality foods... removing aggressive tankmates that antagonize the others... stabilizing water parameters if they are variable at short time scales (within the day or week, like you would not want swings in temp or pH that are high, or salinity)... maintaining a stable temperature and running it in the 75-79 degree range 24 hours a day/365 is a goal for most marine fish. Many people don’t know that tank temp drifts for them unless they check frequently or have a controller and use it. I hope you can get the fish healthy. Some think you have to go fallow and QT in separate tanks to get rid of it. I personally don’t think I would do that to a fish or group of fish unless I had a great appropriate QT system for that purpose. Most people don’t. It can be made a non issue with other methods.
I agree with your suggestions that you can use the DT fallow / proper QT Method to hopefully rid a system of Ich, a discussion of the parasite life cycle is a good idea, to help increase understanding. It is a long road to beat it completely, and not one all hobbyists are equipped to deal with or have physical space to accommodate, which was the reason for my post being worded the way it was. I was not implying that the parasites would go away because of good husbandry, I was implying the fish would not be bothered by them anymore if they were more “fit” to do that.If you want to manage it then I agree with the above of reducing stressors and providing stability.

Good topic to ask Bobby to discuss when he does his zoom call for the club.
