Chlorine Lock ?

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.

Brown / yellow dust that turned green when you swept it?

[mjsboone]

I would say more greenish brownish-clumpy. It has been over a week since being swept and with the filter pretty much going all the daylight hours, today was the first day that I looked at it very still. There was a lot of junk on the bottom. Pool has not had much use to stir it up. Could I still have algae or even dead algae settled on bottom?

Just went out and looked at pool again. Looks great-clear and sparkly. Could some of that staining disappeared this quickly??? Within the past 2 hours???
