This is my first post so thanks for taking the time to read it and offer advise. I bought a house with a 16,000 gal, SWG, VSP pump and have been lurking around this site for a week. This was a divorce and the pool was poorly maintained for 9 months because Mr. Hubby was booted from the property. First things first, I ordered and received my TFTestkit XL arrived and the results indicate the water is out of whack.
pH 7.5 (surprise)
Pool Math says I need to replace 33% of the water due to high CYA and add other chemicals later.
My question is: After I replace the water, do I tune up the salt, TC, pH, TA and CH in that order. Is it better to dump all Pool Math recommended chemicals in at one time or maybe add them over 3-4 days to let the percolate. And how often should I test during the healing period?
