Hello everybody. I am new to TFP and relatively new to pool ownership. I have found this site to be very helpful and have recently gone through the shock process to eliminate algae from my pool. I am now working on getting everything in balance and ready for the swim season. I have an 18,000 gallon in ground SWCG pool with spillover spa and a separate waterfall. The water currently looks great. Here are my current readings as of this morning:
I did the tests myself with the Taylor K-1005 for PH, TA, CH and CYA. I used the Taylor K-1515 FAS-DPD for the chlorine tests and the Taylor K-1766 for the salt.
Based on output from Pool Calculator I added 250 ounces of 14.5 acid this morning after the reading to lower TA and PH. It looks like I also need to bring my CYA up to at least 60 because I have a SWCG and I also want to get my salt up to about 3100. So now my questions:
- Does it matter in which order I raise CYA and salt? Can I do both at the same time?
- How long should I wait to do my next TA test and do I keep lowering with more acid each time the PH has returned to normal range?
- Does my spa spillover contribute to PH rise as I run it each time my filter is on (8 hours a day)?
- Anything else based on my test results?
