My tank has been fishless for about 2 weeks due to a nasty gill fluke infestation. (Yes it was flukes please don't ask if I'm sure .) Anyways there is no coral or inverts, the tank is at 82 degrees, and I've replaced all the sand. I know I still have a couple weeks to go but is there something I can do to guarantee all parasites are dead whenever I go to put fish in?
