Watermom,

Thanks for the reply.

Good to know my TA is fine. I will leave it alone and add some muratic acid tonight to drop the pH a little.

I was aware the hardness was not a major concern in a vinyl pool. They had said it has an effect on my heater components. Do you know if that is a valid concern or not?

Since there is a 5 year warranty on the pool I don't want to give them any reason to deny my repair claims if need be.

I will do another CYA test in a week or so. Give me a chance to try out my new 2006-C kit that just showed up.
