Thanks! how much of a water change did you do? i might need some more buckets, hahaI put my feather dusters back in about 3 days after the final water change (after the second dose) without any problems.
To me, it seemed like Prazi quit doing its job at day 3. So if you dosed on Friday, it will pretty much be broken down by Monday for sure. But you have to do a final water change before putting the dusters back in.
