Here are my test results today, and given what pool math suggested, I'm thinking I should replace the % of water before I add stabilizer.
FC - 0
PH - 7.4
TA - 150
CH - 350
CYA - 0
Poolmath says to replace 14% of the water to get the CH down and also says to add 150 oz of stabilizer. I'm on a community well, and since I already am at 0 for the CYA, I'm thinking the water replacement should come first. Then I should retest as I know my alkalinity will rise. Somewhere in there I will need to lower my PH, but not sure of the correct sequence to add the chemicals, given my numbers. Any help is much appreciated.
