I have been slowly learning my newly resurfaced pool. We filled it in May, and TA has finally come down. pH is stabilizing, needing only small additions of muriatic acid every few days. Despite all the torrential rains that have had me dumping more than a foot of water over the past month, I think I have CYA where it needs to be (barring too much more water exchange). Calcium hardness has been dropping a little, though. Do I need to be concerned with CH right now? I know that after a couple dry weeks I may have to add water, which will bring CH up some.
My numbers from the Taylor 2006:
FC 5.5. pH 7.8 (lowering it to 7.4 today). TA 60. CH 230. CYA 70. Salt 3000.
I measured less than 0.5 CC today, which seems to be the norm with clouds, storms, and lots of tree debris in the pool. Usually there is no CC.
