    Reducing Cl

    What is the best way to reduce the Cl in a pool without messing up the water chemistry? My Taylor test kit book talks about Sodium Thiosulfate Hydrate-5 being used to reduce Cl levels but I'm not exactly sure what that is and if it affects pH, alkalinity,.... Does this have a more common name or is it in a more common form?

    Sodium Thiosulfate is sold as chlorine neutralizer, see for example here. It would tend to increase PH a little. It is ocasionally difficult to find because it is rare to need to reduce the chlorine level, it is fairly expensive, and sun light normally takes care of lowering chlorine levels without any chemical assistance.

    What Jason said. Stop adding chlorine to the water, and let the sunshine in.
