Photo-Flo

[Axle]

I personally have never used it but i did some searching on the internet about this problem of yours and have come up with this:

Glen Johnson off the photo.net forums You can use all the photo-flo you want, but if you use it with the tap water here in Dayton, you'll end up with a cloud of white precipitate coating your film. The water here is HARD. Everyone I know at least uses distilled water for their final rinse. The photo-flo prevents spotting, but it doesn't prevent sheeting. The disolved solids have to go somewhere. They don't leave the suface by evaporation.

so most don't use photo-flo

i haven't used before this class either
