Chlorine Lock ?

[mjsboone]

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???

Yes, if the stains were organic, high chlorine can take care of them. Even though your water looks clear, still keep high chlorine until you meet the 3 criteria posted above.

Noticing some changes in pool this morning and have submitted pool history entries. Would it be possible for Watermom or PoolDoc to take a look?

Thanks for all your guidance and support!
