Hello and thanks in advance for any help. I just installed an Prologic salt system on a vinyl liner pool I built about 6 years ago. I dumped 400 lbs. of salt in the deep end of an 18,000 gallon pool. When I came back a few hours later to stir up the dissolving salt everything was already turning brown. The steps, skimmers and main drain had a reddish tint to them and the liner had a brownish tint. What can I do to lift these stains, before my clients tell me they want a new liner?
