Chlorine Lock ?

I have added 5 entries on the pool history form and submitted. For those that can access those history forms that I have submitted, are there any thoughts on my progress getting past this "chlorine lock". Pool is clear, but I don't think I'm there yet. Not adding nearly the amount of bleach everyday, but still adding. I hope I can get to the maintenance mode soon.

Thanks to all.

I don't have access to the data, but I would say you likely can consider yourself in maintenance mode. You'll need to keep the FC between 10% to 20% of the 130 CYA you tested going forward (if you don't drain). I'd shoot for keeping it at about 19FC for the rest of the season and see how that goes. Remember to keep testing the FC every 1-2 days to be sure. Consider this the key and the chlorine unlocked :)

Good luck.

The FC has been at 19.5 the last three testings but I think somewhere back in this thread, watermom advised to get it to 25ppm and hold and make sure CC less than .5 (the CC was 1.5 this morning), then back off until 10-15ppm and maintain. Ive been adding bleach to get up to the 25ppm but if I am understanding correctly, I can hold it at 19ppm, test every couple of days, and add bleach if necessary. PH 7.6 this am. It is to be sunny, hot and humid here for the week-normal summer. Will that full blown sun on the pool all day make my numbers go haywire again? Hang in there with me! I think I'm starting to "get it". My neighbor told me yesterday my pool was sparkling! :)

Take a look back on the thread. The 25ppm recommendation was for a shock level when you posted a CYA reading of 80. At 130 CYA, you're target numbers become respectfully higher.

Your numbers are not "haywire" as long you know what they mean and what to do (or not to do). That's when you know you've got it :)

Appreciated. Thanks!

Sorry to disagree Big Splash, but with a reported CC of 1.5, mjsboone is not in maintenance mode just yet.

Continue to keep the chlorine at 25ppm and test daily. Keep it at that level until you pass the 3 criteria:

1) Don't lose more than 1ppm from sundown one evening until within an hour of sunrise the next morning
2) CC of no higher than 0.5ppm
3) Water is clear

Then, keep it high for one additional day and then you can let the chlorine drift down and keep it between 8-15ppm ALL the time.

Thanks, WaterMom.

@mjsboone: I just checked your form results, and your pool definitely seems to be improving over the interval you recorded (8/1 - 8/4). In particular, I noticed the gradually diminishing CC levels (3.0, 2.0, 2.0, 1.5, 0.5, 1.5) and the improvement in odor. Both factors suggest you are on the right track, and are close to the 'finish line'.

Thank you PoolDoc. I will keep testing and posting until everything is square!

I was at 20ppm FC and CC 1 last night and added bleach- 1 1/2 jugs.
This morning I as at 24ppm FC and 1 CC- added 1/2 jug.
These numbers posted in history log.

I swept the pool this morning to waste and noticed a lot of greenish debris that was clumped on bottom-all out now! Also, there appears to be some staining on the liner that was not there before. Water is clear.
