Here are my test results with my new TF-100:
CH 150 (we have copper that DH added, so I added the two extra R-0012 drops prior to R0011L and included them)
On 5/25, the last time tested (at Leslie's Pool Supplies using a drop test) the CH was noted at 210. Is it possible for CH to drop that fast?
Is my FC too low for my CYA?
The pool has a solar blanket on it now until this weekend when we are ready to use it and the temp is going up to the nineties!!!
