Oh thanks for pointing that out. I had read the first couple sentences and then moved on since I thought he was saying something contrary to what my experience has been. Should have read the whole thing. His experience is pretty much exactly the same as mine.

BTW, I got the advice on FW dips on new fish from the former owner of Aquarium Sales & Service. They were THE sw shop in SA for around 20 yrs. I would guess he has done it on tens of thousands of fish.
