Hello
I just received my new TF-100 refill kit yesterday (all new reagents) and did comprehensive testing of my pool water today. I did a partial drain (70%) in April 15. I tested the CYA three times since I drained the pool and got 20-30 range. I only use bleach for my CL source.
Here are my results:
FC-3
PH-7.5
CC-0.5
CYA- 0
TA - 90
CH - 200
Water Temp - 87F
my concern is the CYA. Prior to doing a partial drain, my CYA was about 50. Now it is zero, the CYA reagent added to the pool water is almost crystal clear. Therefore I postulated that the new R13 reagent that came yesterday was defective. So I used another bottle from last year (APR 2015) and got the same results. My worry is that an indoor pool should be accumulating some CC since it has no sunlight to burn it off.
What, if anything am I doing wrong, and what do I need to be concerned about.
Thanks
Best
