I did my first dose of Prazi last Monday. I have been on the road a lot and don't have water mixed for a water change. Everything I have read says to dose wait 5-7 days then dose again. Am I going to lose effectiveness waiting another day for the water change before I dose so 8 days. What I have seen says prazi is done after 3 days and the wc is to keep from having an ammonia spike from parasite die off. I haven't had any ammonia issues but the fish were transferred to a fully cycled qt for treatment, so the load was probably small. What do you guys think is the best course of action.
