EXACTLY!!! I have often suspected that Prazi Pond was cut with something harmless because in the past when I've used it I had to dose several times back to back (weekly intervals with water changes) to get any real results. I've even double dosed Prazi Pond with absolutely no ill effects at all. Did it for years. What I used this time was what I suspect is a full strength product purchased in bulk or it is cut with something toxic to the fish and not meant to be used for fish. Not sure of the original source but will try to find out.
