Treatment with a white spot cure worked very well and the fish got better and the cysts all burst (but left a hard shell on the tank and bog wood, these scraped off OK though)
Recently these cysts have returned but none of the fish in my tank are showing any of the signs of white spot. I have tried upping the temps to 32*C, but it runs at 30*C anyway.
The only fish showing anything different are a group of 3 gouramis that have some possible white patches on their tail fins (although I could be just imagining this
