I had the unfortunate timing of noticing ich on my Threadfin and Longnose Butterfly about a couple weeks out from an extended vacation I was about to take. Entirely my fault, as all fish were bought quarantined so I suspect it was brought in through a piece of macro that I deemed safe. Anyway after weighing my options and with the short time frame that I had I made the choice to put my tank into hypo in the hopes that it would solve the problem. Salinity was checked by a Hanna reader while I was gone, and three weeks later upon my return I was dismayed to see that there were still signs of ich on a few of my fish. At that point I was all ready to go nuclear with copper in my DT as I had no holding tank to treat everyone in while I went fallow. I'm running a FOWLR and moved my inverts over to a small temporary tank so I'm perfectly fine with dosing my DT and waiting an extended period of time to run Cuprisorb/etc to get it all out of the rock. In the process of slowly raising back my salinity to start Coppersafe I noticed that while there were still definitely spots on my fish, my butterflies especially, it never looked like outbreak levels of spots that I was accustomed to seeing when others would post about ich on their fish. The white spots on the butterflies would always be under 20 or so, and that would be on the high end. My wrasses are practically untouched, at most I would only see a spot or two every few days. My Banggai Cardinals have yet to show any outward signs of ich although I know it can also affect the gills. I also have a baby 1-1.25" Convict tang in the tank that I fully expected to be an ich magnet, but I have yet to see any spots on it.
Not to jinx myself or anything, but with all this I'd like to think that I've been able to manage the ich so far. I feed mysis/brine/TDO twice a day and soaked with selcon and every 1-2 weeks I do about a 20% water change where I siphon up some of the sand as well. I do have Coppersafe on hand in case anything starts to go wrong, but I've been hesitant with pushing the big red button especially since wrasses can be a little hit or miss with copper. Just looking for any input or other perspectives.
