Need some advice on what to do/check/watch. Pool read low on salt at open so went to walmart and got 4 bags of the clorox pool salt cause it was $1 cheaper than mortons and no water softner salt in the store. Been dealing with a bunch of rain but salt level was 5-600ppm lower than i expected out of it so i googled it+tfp so i would end up back here and found loads of bad reviews. Water looks fine and tests good on fc currently but what do i need to keep an eye on with it?
