I'm currently treating my tank for flukes (my poor blenny had 13 fall off of him in a FW dip - crazy!), and dosed PraziPro two days ago. I know that the general directions are dose once, wait a week, do a WC, and dose again to deal with any hatchlings. However, I'd like to do a WC today or tomorrow if at all possible, since I'm getting ready to go on a trip and like to have my water as pristine as possible just in case. I usually do 3-4 20% WC's in the days leading up to the trip, and was wondering if it would hurt the treatment to go ahead and do a WC. Prazi is only active for 48 hours, but I know that certain other ingredients stay in the water until they're manually removed.
