    Liquid Chlorine adding salt to pool

    We have been successfully maintaining our pool through out this summer using using liquid chlorine at 10% and muriatic acid. I have Taylor test kit and use it faithfully. I was talking a friend that is in the pool maintenance business and told be that adding liquid chlorine adds salt to the water and can cause salt levels to be too high which can be corrosive. He is recommending a Taylor Test kit K1766. I do not have a SWG.

    My question is do I really need to be concerned about this?

    Thanks!

    Every gallon of 10% chlorine adds 16ppm of salt. (Pool Math) Seeing how SWG pools are generally in the thousands, it's not a problem.

    No,

    For every 10 ppm Free Chlorine (FC) in chlorinating liquid or bleach, there is also around 8-9 ppm salt. When the chlorine gets used/consumed, there is another 8-9 ppm salt for a total of 17 ppm salt.

    That means that all chlorine pools (except pools with SWG) have rising salt,

    Will that sal become a problem. Generally no. Most folks salt will never get above 2000 or so. But you probably won't taste it till its above 6000. Ocean water is about 35000.

    Harm the pool. If you have soft rock around the pool ----- maybe if it gets high enough. I would be much more concerned with ph and your total saturation index.

    Trichlor, Dichlor, Cal-Hypo and LithHypo all add salt as well - though maybe a slightly lower rate.

    Of all the chemicals that build up due to manual chlorination through any method - salt is the least offensive.
