I am thinking about installing a SWG system, but have a somewhat different concern than those I have seen addressed here. We have a Springer Spaniel that loves the pool. She gets in anytime it is opened and swims for 10-20 minutes. During this time she barks a lot and swallows a lot of water. What if any health issues should I be concerned about with the salt content in a SWG pool?

My second question is, when my pool guys say you fixture the amount of salt you need by doing a TDS check on the pool is he assuming that all the dissolved solids are NaCl. It would seem that the TDS figure could include other dissolved solids in addition to NaCl.

Thanks
