I wanted to know if there is a calculator or instruction sheet y'all recommend for how much sodium thiosulfate to add in case my free chlorine gets out of whack again from over-zealous shocking. (it was as high as 65 before dumping in about 24 oz yesterday, dropped like a rock)
I've looked all over the internet and am finding contradictory advice, anything from 0.5 oz to about 5 oz to decrease FC by 1 ppm for a 10,000 gallon pool.
I was aiming for about 0.75 oz per 1 ppm decrease in my 2800 gallon pool as a conservative estimate.
I am grateful for any suggestions!
