Hello,
I use 12.5% liquid chlorine and 31.45% muriatic acid for maintenance. I have been battling high PH and somewhat high TA for a year now and can’t get it down.
I moved in about a year ago and after testing the water the CYA was so high I couldn’t measure it. The TA was 180 and PH constantly reading at 8 using my Taylor Test kit however it could be higher since the reading tops at 8.0 ph. Since the CYA was so high, I decided to drain the pool, replace some lights, and refill. After refilling and getting my CYA to 40 my TA ranges from 120-140 however my PH is always reading 8 on the test kit. I add acid and chlorine every other day and it brings it down to 7.6 however 2 days go by and it’s right back to 8.0. I have a 20k gallon inground gunite pool and spa. The spa has a spillway that is only on (spilling over) for 30 minutes per day to chlorinate the spa. Reading here the high TA isn’t necessarily a problem however, is it normal to be adding acid every 2 days to bring the PH down for 1-2 days? I tried to add large amounts (1 gallon) tried to add what I am currently doing (1qt every other day) along with 3qts chlorine however the Ph always goes back up. What else can I do? Should I try dry acid? Should I not worry about it and just assume that’s part of my maintenance routine? This is the first house I have owned with a pool like this so just want to make sure this is normal. Water is clear, I get yellow algae spots on the shallow steps that I have to brush off 1x per week. Also guessing that’s part of the maintenance.
Thank you for your help!!
