Thank you both, yes, I'll get some CYA and add it..."dose it every night" hmmm, how much do I add? If I only test once after a week how will I know how much to add? The Walmart test kit I bought came with two tests for CYA, I used one today.

Also, will adding some of the pool salt make the water more gentle on the skin? My dd has sensitive skin and after a few days of regular swimming the backs of her knees become red and rashy. (After a swim in a hotel or YMCA pool her whole body breaks out!).

We'd love to switch to a SWG but couldn't swing the expense this year.

Thanks,
