Thanks for the replies. My thinking on the Aeration with lowered PH was from the fact we are getting scaling on the perimeter of the pool. I think I realize now that was from letting the PH get too high at one point. (correct?)

I will contniue to raise my TA with Baking soda as needed. I will return the triclor tablets and get pure CYA stablizer.

Thanks for the comments.
