As suspected, I have very low salt in my pool. The recommended level on the chlorine generator reads between (min) 4,000 PPM - (max) 6,000 PPM. Did a salt test and reads 1990 PPM, so it needs alot of salt.
My pool is 50,000, and on the 'amount salt needed' table says for it to reach 3000 PPM, I need 327 kg.
To get it around 4500 PPM, guess it's around an extra 280 kgs. Does that sound excessive or does it sound right?
