adjust cya before or after shocking

[Kateyru]

Morning! PH is 7.2 and chlorine is still at 5. I misspoke yesterday about the color. I would say it is a medium yellow at most and not dark. I'm planning to get distilled water this morning to do the test without a kit since I haven't heard that the 2006 kit has shipped. I am leaving town in 24 hours (Fri am) and will be back on Sunday evening. Any way to shock with bleach (based on distilled water test results) in 24 hours successfully or will I be wasting bleach?
Thanks.

Medium yellow meaning matches the color of the 5ppm on the comparator or darker than that?
A one to one dilution (shot glass method - Multiply result by 2) should give you a good idea if you're in range.
Four gallons of 6% bleach should raise your FC 11ppm which puts you at shock level if the initial is 5ppm.
A three to one dilution (Multiply result by 4) should indicate if you're at shock level.
Run the pump, brush the pool, test again this evening and bring it back to shock as necessary.
Are you planning to leave the pump running while you're gone?

Have a great trip!

Medium yellow meaning slightly darker than color of 5ppm. I just retested chlorine with kit and got about the same as before (slightly darker than 5). Then I mixed 1/4 c. distilled water and 1/4 c. pool water and tested and got 5 ppm. so if I multiply that by 2, I'm at 10. Pool calculator says to go from 10 to 15 ppm, I need to add 1 gal., 3 qts and 1 c bleach (6%, I'm clear on that). After I add bleach and scrub, how often should l check to see if I'm at shock level? Also, is 3 to 1 dilution 3 parts pool water or 3 parts distilled water? Can you see that I am getting anal...
Does this sound correct?
Sure, I can leave the pump running. Thanks, I'm off to visit my daughter and her family. My 2 ADORABLE granddaughters (ages 8 1/2 and 7) LOVE the pool and go in NO MATTER WHAT the outdoor temperature is. Sometimes they aren't in long They first went "naked swimming" 2 days after Christmas 4 years ago. One of the funniest thing I have ever seen...lots of squealing!
I'll have to add you to my Christmas card list after all this help

During the process of shocking a pool, the more often you can check and bump the chlorine back up, the quicker the pool will clear--it is the consistency of shock level that will kill the algae off the quickest. Every 2-3 hours would be great, but that's not feasible for most people, so at a minimum I would say 2-3 times a day, or however often you can. Also, 3 to 1 dilution means 1 part pool water, 3 parts distilled water--the goal is to dilute the pool sample enough to produce levels that can be read by your tester. You'll love the K-2006 kit--it makes this SO much easier!

Today I can test frequently, yea! so will do that. can't wait for the K-2006 kit.
I just realized that different people have responded to me. THANKS TO ALL!!!!!!!!!

Yeah, we're all sorta interchangeable

Enjoy your visit with your grandkids

To be clear: leave the pump on only if there is no chance that your skimmer and drains won't get clogged with debris and that your filter won't get filled before your return. Otherwise, do what you can today shut it down while you're gone and go at it again when you get back.

BTW, for 1 gal., 3 qts and 1 c, I'd be inclined to put in two gallons. This is not exact.
