8500 gal SWG vinyl pool
Water temp 53F
Following stats using Taylor K-2006 kit
Salt per swg when water was 56F 3200PPM
pH 7.8 close to 8.0
Borates approx 60
So here's my confusion. I went to test the FC filled up to 10mL mark added two dippers of R870. Zero reaction no pink hint at all. Ok maybe the reagent is bad the bottle looked kind of nasty anyways, I ordered a new bottle of R0870 and retested. No reaction again. Thinking maybe pool really has zero CL in it due to the tons of rain and draining down level in pool. So I added 1/4 cap on the Clorox 6% bleach bottle into the test comparator filled to 44mL, surely that will turn mega pink when I add the R0870. Added two dippers and thick chunks of the new reagent turned a deep red then when I shook it it clears back up.
Am I dealing with absolutely no FC or Two bottles of bad R0870 (1 fresh brand new)? Thinking about giving th pool sample water a heating via a water bath to being up the temp but don't think that will help. Or am I testing the CL wrong?
