First off, let me say, like so many others: this site is awesome. The knowledge and support is incredible.
New pool owner here: in-ground gunite, with fill in January, 2009
My numbers today are:
Cal. Hardness: 510
CSI (at 68 degrees): +.7
Water is crystal clear.
My PH is constantly moving up...seems like every other day I'm hitting with acid.
The CH has always been high - yet when I test our fill water, it's more in the 200 range.
Is what I'm experiencing (the creeping PH and high CH) associated with the new plaster cure?
I understand it can take months to completely cure...
Any other ideas/suggestions...? Or do we seem to be ok?
Thanks in advance for any insight.
