swimming pool salt water with chlorine water?

Posted by on . 2 comments.


i have a swimming poo and a spa. i drained the spa to acid wash it but instead of filling it back up i filled it up with the water from the pool forgetting that the pool water has salt because i have an aq-rite salt generator in the pool and i treat the water on the spa with chlorine tabs. Could there be a problem if i have water with salt in the spa and my actual chlorinator uses chlorine tabs????

    The person above says that you should use sea water as a comparison to salt water pools….sea water has many more times salt than a properly salted pool….a pool has less salt than human tears…

    Yes. There can definitely be a problem. Salt water is highly corrosive. When people make the switch from a chlorine pool to a salt pool, they have to change out their lining, pumps, filters, and basically anything else that touches the salt water. The salt water might eat your pumps and lining away unless they are made from salt water resistant materials. Check what material your spa is made from.

    The following website will help you to find out which materials are resistant to salt water. For the chemical, select "Sea Water," as that is the closest chemical to the salt water found in your pool.

    Sea water is a good comparison because average sea water is 3.5% by volume salt. Compare that to 0.9% by volume for human tears and 0.2-0.48% for a properly salted pool. These numbers are small in comparison to a saturated solution (~25% by weight salt) so they are in the same ballpark. Regardless, no matter how much salt is included, salt water can damage your system.
