My ps uses regular sifto food grade salt.He used it in my pool and i had no problems with it all of last year.
Do you see any problems with useing regular food grade salt?
This salt cost me 5.00 for a 20kl bag.
The ps owner is a friend and he told me that the only difference between table salt and the pool salt is that table salt has a agent that stops
the salt from turning brown while cooking.He uses food grade salt for all the pools that he installs.
