Free Chlorine Vs Total Chlorine Salt Water Pool. 2700 ppm to 3400 ppm. Dark surfaces surrounding the pool can acquire “salt rings”.
This makes the pool water much easier on the skin, eyes, and hair. Basically, both chlorine and saltwater pools are inherently similar. Saltwater pools aren’t filled with seawater as many people think.
So, if the free and total chlorine levels are identical, that means there isn’t a presence of combined chlorine in your swimming pool.
In a clean pool, combined chlorine will be 0 which is ideal. Buy now at the pool factory. On the other hand, if the free chlorine level is lower than the total chlorine level, you can use that to calculate the combined chlorine. Electrolysis happens by sending electricity through salt water (sodium chloride, or nacl), which interacts with the chloride ion in the salt.
