    pH at ~7.0. corrected. how long to wait and retest

    got heavy rainfall last night. was glad to see pool, while overflowing, is still sparkling clear. test results

    FC - 4 - added 20 oz bleach

    CC - .5 (what should combined chlorine # be anyway? and should i even worry about it? it was an extra step on kit instructions so i did it)

    pH - ~7.0 - it was pretty dang light yellow colored. i put it in as 7.0 on pool calc. added borax as instructed plus added 12 oz baking soda for TA as instructed.

    TA - 90

    CYA - assuming still 0. this is day two. my kids squeezed / shook sock on ladder yesterday, dissolving granules. clouded pool up for about 15 minutes. none on pool bottom anywhere. it may be absorbed. i test CYA tomorrow morning. being patient since there isnt much reagent in k-2006 kit for CYA

    pump is going, soda and borax broadcast spread across pool. stirred a bit with skimmer net.

    how long should i wait to retest pH before swimming resumes?

    thanks!

    You only need to wait an hour after adjusting the PH before you can retest.

    I would learn to be really patient with the CYA test. It takes a lot of chemical to run the test, so I would advise finding the number and then adding the required amount and waiting at least a week if not two before re-checking.

    IE - If you know you're at 0 and it takes 5lbs of the stuff to bring it up, add the stuff, let it dissolve completely, and check a 4-7 days after the sock was emptied. Just my two cents, but I may've tested the CYA too much early on, and it takes a good amount of chemical to run the test. Patience is key with that one.
