I have done a fresh water dip this morning on a second fish before I added Prazipro. I didn't do a major water change since it's been 2 days since my last one. I did do a 5 gallon wc again today before I added the Prazipro. but I know I need to do another dip. at what frequency do I need to do it again. every day. every other day or what 5 days and then do another water change and read Prazipro and another fresh water dip. ?
