Hi.
My GSP has had white spots on it for about two weeks, which neither QuickCure nor Clout were able to cure. I used QuickCure for 7 days straight, but the temperature was raised to 82 or so, so that should have been sufficient. I'm on the 4th day of treatment with Clout. On the package it reads that if a parasite is still present 24 h after treatment, I'm to do a 25% water change and treat again. I didn't know whether to treat the tank on the second day with the full amount of medicine (as though I was treating it for the first time, even though only 25% of the water was new), or with only 25% more medicine. The guy at my LFS told me that I should treat the tank as per the additional 25% only. Is this correct?
Regardless, here are photos of the puffer (and the spots). They seem to be getting worse daily. The puffer started to be more active after initial treatment with Clout, but his appetite's been gone - entirely - for well over a week. Now he seems to be struggling, but at least in an active way, as though he's bothered and wants to get away from the blue Clout-water. However, sometimes he seems to be losing his balance/orientation, or to be "passing out" or to be in a daze. He's breathing hard continuously.
The SG is 1.006 (I know it should be higher, but I've been raising it only 0.002 per week, as advised).
Okay, here are the photos (please see especially the 3rd and 4th ones):




Please advise me as to what I should do.
Many thanks,
puffer_puff
