    best time to test / add chemicals?

    well, other than that little mishap the other day with the new sandfilter shooting sand in my pool ive had 0 problems with my pool. here is my latest results as of 9 am today

    pH - 7.6 (ranges from 7.6-7.8 daily without me doing anything)

    FC - 3.5 (adding ~50 - 55oz of 8% daily to keep running pool around 9)

    CC - zero every morning

    CYA - 90 ( a little high i know, but pool is in full sun all day, and i plan on draining a bit in a week or so to put in hayward skimmer, so that will come down some when i refill)

    CH - 70

    TA - 100

    i get up and test this pool every morning religously about 830-900 am with my K-2006 kit for FC, CC, and pH. i test every sunday for TA. today was first CH test. my pump runs 6 hours coming on at 8. i test, and add chemicals for the day.

    pool is crystal clear.

    do you guys test / add chem in morning or evening? or does it matter?

    also, my TA has held solid 100 for near two weeks. thinking if it is 100 next sunday, i may start testing it every other week rather than weekly.

    ill probably do CH test monthly

    i realize what im doing is working, just curious.

    Everything you're doing sounds fine. Some people dose the bleach in the evening to delay breakdown in the sun until the next morning, but with a clean pool, it really doesn't matter.

    Personally, I test twice a day (I'm a bit OCD about the pool), and dose as needed in the evenings. Skimming, then brushing/vacuuming as needed in the AM.

    once I get zeroed in I just test my CL daily.. and do a full test on the weekend.. my pool seems to take 1.5Ltrs of 12% CL every night. I leave for work at 5:30'ish every day so no time to do pool stuff in the AM.
