Thanks Tim. I've used formalin before, I know how it affects the house
While FW dips may help alleviate the parasite/protazoan on the fish, it does little to the free floating ones. I've reduced the tank a bit, and will drop it to 1.010 long term, but will continue with the chloroquine. It has no apparent ill effects on the fish, keeps the bacterial filter intact, and other than photosensitivity, keeps it's levels in the tank.
Since I now have a matured system running, I'll keep it going until I replace fish. I still can't keep a q tank going full time, so that's not an option long term.
