So if I measured my chemistry 2 days ago and we were balanced including LSI and CSI...and then today I measured again and pH was a wee high at 8 with 1 drop needed to bring it down to 7.6, so 9 ounces of MA was added. Tested again a few hours later and everything is nailed on the chemistry.
So how long does something have to be 'off' before the pool starts being subject to scaling or corrosion? 1 hour and the process starts? 1 day? 1 week?
Not a panic question...a curiosity question.
