The pool is crystal clear now. Have kept the chlorine levels up where reccomended. My problem now is there are still a few small spots of the brown on one side of the pool. I know I have to keep the levels up until all gone. I have ordered the reagents for my Taylor K-2006 kit but they will not be here until at least Tuesday. I don't have enough left to see how high the levels of chlorine are today so I don't know how much bleach to add to keep it at 75. I have phoned everywhere I know to phone in this area looking for reagent. No one has it. Does anyone know of anyplace that has the reagents in the Chattanooga/Cleveland TN area? If not is there another way anyone knows of to test for the level of chlorine? I would hate to have to start all over.
