    I've switched to distilled water for making photographic solutions, especially developers. I've had issues with regards to calcium carbonate deposits forming in certain solutions. Since the switch, there hasn't been any problems.

    Developer, fixer and hypo-clearing agents should NOT be made with distilled water. They were not formulated for using such water and will not yield optimal results.

    Photo-flo should be made with distilled water.

    This doesn't make any sense.

    Distilled water is pure water - H2O. Tap water is pure water that has a variety of contaminants in it, but the contaminants vary from place to place. How could a chemical manufacturer possibly design a developer, fixer or hypoclear for optimum use in tap water without knowing specifically the composition of that tap water? And how could he possibly market something on a global basis when the actual composition of tap water varies so widely.

    No, the notion that photo chemicals were designed for optimum use in tap water rather than distilled water fails the common sense test.

    Some developers have been designed to tolerate most tap water. Perhaps in touting that fact, the statement was made that tap water is optimum, but it should have read "There is no need for distilled water. Optimum results will be obtained with tap water." That statement may or may not be true. I have encountered tap water that was not fit to drink because of the amount of chlorine in it. You don't always realize it. When I moved to this place I got used to the deepwell water that is cool in hottest weather, sweet to the taste and, unfortunately for carbonate developers, very hard, but that's good for the heart. When I visit my old haunts, I can hardly stand to wash my face for the chlorine in the water.

    I use a lot of borax and sodium metaborate in my developers because they do not require either distilled water or EDTA.

    Could you maybe provide a source or authority cite for this? Especially for developer, fix and hypo-clear?

    I always give my film a final bath in distilled water with some wetting agent, but that's really all I do because the tap water is very good here.
