Hello. We recently purchased a home with a salt water pool that was built in 2006. We have been working very hard to learn to maintain the pool adequately. The pool is approximately 25,000 gallons. It also has a spa with a waterfall and a jumping ledge with 3 fans. We have noticed a lot of white scaling on the waterfall and the ledge and have been told that it is due to a chronically high pH. We have a 4 cartridge filter pod and a Jandy Lite 2 Heater System, as well as some type of electronic auto chlorinating generator. After we read posts on this forum, we purchased the TF-100 kit and have performed the tests on two occasions now.
CL & Br were > 5 & >10.
pH was > 8.2
FC = 8, CC= 0, TC= 8 ppm
CH = 270 ppm
TA = 110
On 12/15/14 we had the water tested and the Cl Br were still over 5 & over 10, and the pH was 7.8. We purchased Muriatic Acid and were told to use approximately 1/2 gallon followed 2 hrs later by 2 scoops of the high concentrated shock. We tested the Cl & Br again on 12/18/14 & it was still the same as on 12/15. We added another 1/4 of the gallon of acid.
Cl & Br: > 5 & > 10
FC: 12, CC: 0, TC: 12 ppm
CH: 325 ppm
We added the rest of the gallon of acid this morning after the test. By looking at how these numbers are trending, could someone please advise us as to what our next actions should be? Of note, we believe the Previous owners had pH problems as they left some pH reducer in the garage when they moved.
Thanks in advance for the help and advice!
