Hello. This is my first post and I have spent that last 2 hours reading Pool School and searching the forums in hopes of finding out what is going on with my 2-month old, Salt, 20K gal pool & spa. Here are today's numbers from Leslies:
Salt 3300 (they told me I need to decrease my salt cell setting)
CH 100 (yes I know this is super low but they said with my high chlorine levels, I should hold off on treating for this until we test again next week and see if that number is still this low)
pH 8 (high...have added 20 oz of muriatic acid). This tested at 8 last month as well.
Ok....so the issue is the discoloration of my antigua blue wet-edge. There are areas that are blue (like the should be) & areas that are a light brown (large areas...not just spots). The steps look very mottled with brown-ish colors most apparent at the edges and corners. The color is almost like sand. I've researched calcium scaling and don't' know if that's what is going on or not--isn't that usually a white stain? PB has recommended a no-drain acid wash--which they said they would handle. I have brushed with a combo nylon/ss brush every day for a week and have not seen any improvement in the discolorations. Oh...and the pH of the fill water is 8---so obviously I was facing an uphill battle from the minute I started filling this pool.
Any help you guys can give would be so appreciated. I am feeling frustrated b/c it's nearing time when we can finally enjoy the pool here in TX but yet the bottom and sides look ugly (especially apparent on cloudy days).
