CH--can it fall that fast?

Here are my test results with my new TF-100:
FC 5
CC 0
TC 5
pH 7.3
T/A 120
CH 150 (we have copper that DH added, so I added the two extra R-0012 drops prior to R0011L and included them)
CYA 40
Temp 70

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!!!

Hi, Maria,

My intial reaction to your results is that they are nearly perfect! :lol: :lol:

How does your water look?

Do you have a gunite or a vinyl pool?

Ch is generally stable in pools so I would suspect a testing error on Leslie's part. Over and over, we have all learned that we test more accurately than the pool store.

For a gunite pool, CH is a little low.....200-400 is better.....I'd add a little to bring it up but maybe test it once more to confirm your first test.

Again, the rest of your numbers are absolutely on the money....Nice work! :lol:
