Hello:

I was hoping to close the pool this weekend. I super-chlorinated over a week ago (I usually do before closing), but now that I have my Taylor K2006... I'm testing more accurately, and wondering what the pro's might advise me to do.

FC = 15
CC = 0
pH = 7.5
CYA = 40 < 50

This week, I purchased a Taylor K1106 Phosphate test kit. My phosphate level is approx. 375ppb. I have some PhosFree and intend to add the recommended dose before shutting down for the winter.

2 questions:

1) The K1106 instructions didn't say anything about chlorine levels prior to testing. After I tested, I was reading the dosage amounts on the PhosFree bottle and noticed it recommends testing when chlorine levels are below 5ppm. Is my Phosphate result skewed due to my FC being so high?

2) Do I need to worry about closing my in-ground, gunite pool with this high FC result? Pool is 35,000 gallons. I use a mesh winter cover.

I'm able to put winter cover on and delay lowering pool level for the time being if needed.

Thanks for sharing any concerns.
