Hello:
I am a "newby" to this site and I appreciate the opportunity to get some good and honest pool information. I have an issue with my pool, 16,000 inground, pebble finish, Hayward VSP, Triton II sand filter.....my cyn levels are way up there....depending on which store you go to test, they are anywhere from 125 ppm to 150 ppm...the strips come in at 150. (Out here the reference range all the pool stores give is 30 - 100 ppm.) Too late to drain here in Scottsdale, Arizona.....air temp. is now hovering around 100 degrees+ everyday, and climbing, and the pool water is 80+ degrees and climbing. At this point, I just want to get through the summer and will definitely drain in our "winter months" of Jan-Feb-March.....and besides, the water rates go way down during those months. So, going forward, I don't know if I should use liquid chlorine or a calcium hypochlorite product which apparently has NO CYN in it, but has lots of calcium in it. Well, my calcium levels are way up there, too. Once again, depending on which pool store I go for testing, the calcium reads they give me range anywhere from 350 to 700+. Of course, this is making me crazy. To make matters worse, the past two months I have been routinely adding Sodium Dichor (chlor brite) as a routine sanitizer, which has even more cyn in it that the tabs. The pool store guys said it had very little stabilizer in it. Yeah, right!!..... I used liquid chlorine for the past several months, from last Sept. to end of March, in an effort to lower CYN naturally, and keep it from climbing. I have also removed the floater with tabs from the pool; also depending on which pool store you go to out here, they will tell you 1 tab per 5,000 gal, or 1 tab per 10,000 gal....I can never get a straight answer from these guys. So, going forward, I'm thinking my option is to go back to using the liquid chlorine, or combine it with occasional bags of calcium hypochlorite or something. I also switched on the valve to put only "soft water" in the pool going forward, about a week ago, since my calcium is also high. I also wanted to clarify about TDS.....the pool stores will give you a big lecture about how liquid chlorine raises TDS and how bad it is for your pool. But now I'm thinking that's because they want people to buy their own store brand products and granules.....not some third party vendor who makes liquid chlorine. In fact, I thought it was a bit strange when I was in the pool store this past week, and they had no liquid chlorine at all. In fact, many of the area stores were all sold out of liquid chlorine. By the way, no one uses the pool except me, and I only go in occasionally to swim laps for exercise, but hopefully would like to swim laps everyday for 30-60 minutes. I only want to keep the chlorine at 1 ppm for swimming, which is a safe level, but I know I will have to kick it up to 2-3 ppm when our air temp. out here in Phoenix hits 105-115, which is coming soon, and stays in that range for several weeks. My pool was remodeled and filled in June of 2014, so the water is just three years old, but it sure is not good water at this point. Any thoughts or suggestions would be greatly appreciated!!
