Should I wait till tomorrow? It says to let it mix in for about 24 to 48 hrs, it'll be just about 24 tonight. I was gonna test in the am and add accordingly.Perform a salt test, then see how much salt you need to add.
I buy at lease one bag more than I think I need, just in case. You'll use it.
Get ready to lug a bunch of salt from the store to your pool
