Problem up front: Cloudy / hazy white spots / streaks / runs on pebble tec floor (Not on the sides). Just a haze, so breaking a piece off to test for calcium type is not possible. Back to intro. So fortunate to have found this group. Thank you in advance. I have reviewed many of the posts on this topic, and I can’t find one that addresses my issue specifically, always a ‘one off’ that makes my challenge different and thereby rules out the proposed solution.
I have a 11,100 GL chlorinated geometric pool built in 2023, in Tucson. It has 9 in floor jets with a cyclone hayward cartridge system. Tucson obviously, hot and hard water. My chemicals are on point, both through a weekly trip to the pool store and my liquid testing kit backs up the pool companies’ verdicts.
Two most recent results:
1. Free Chlorine: 4, PH 7.3-7.4, Alkalinity 110, Calcium hardness 514, Cyn Acid 31, Iron .1, Copper .5 and Phosphate 86.
2. Free Chlorine: 3, PH 7.3, Alkalinity 115, Calcium hardness 558, Cyn Acid 30, Iron .0, Copper .4 and Phosphate 180. (Pool company states they don’t really focus on hardness until above 800 in Tucson because of Central AZ project as a source of water)
Photos attached. I normally shock with 1 lb non stabilized one week, and then 1 lb stabilized the next week, normally 4-6 days apart in the summer (100-108F) at dusk. The granules are dissolved in warm water, dispersed throughout pool and pump / filter runs for 4-5 hours. I also stir up the water with my hand-held skimmer / brush the bottom. The following day I add 1.5 oz of Biodex Skillit for algae maintenance. No algae problems. I also add a tablet of Acuafinnessee softener in the skimmer basket weekly which dissolves in about 4 days (To combat the hardness). Finally 1-2 oz of clorox clarifier every 6-9 days.
During the day, in direct sun – the pool is absolutely beautiful and clear and you can barely notice the white streaks, you have to really be ‘looking’. As dusk sets it – the streaks become more evident, to include the evenings with pool lighting on. The streaks are mostly around the edges, and more prevalent in the shallow end. Shallow end 4', deep end 5'. I maintain the pool myself, but the local pool company who fact checks my water chemistry seams fairly certain after viewing the photos this is a slight calcium build up that should dissipate through brushing. I have not seen those results despite brushing daily and self-vacuuming after a week, to include scrubbing inside the pool with goggles and a hand brush (nylon). My scrubbing from inside the pool days are about to end for winter.
I am at a total loss, wife believes pebble tec is destroyed. Is my only option to drain the pool when its cooler and pressure wash, chorine waash or acid wash…in that order? Is it possible the pebble tec was comphromised during install? Thank you again for any counsel to this new ‘pool maintainer’.
