Clear, but no chlorine???

... The FC has been dropping approx. 2 points during the day and 0-1 overnight. The CC has also been dropping!
Yesterday morning FC=22 CC=0.5.
Yesterday early evening (5:45pm due to rain) FC=20 CC=0. I double checked using a 25ml water sample to be sure and the FC=20.2 CC=0

This morning tested @ 8:30 FC=19 CC=0.

YAY! -> Jumping up and down, screaming YAY!

No more need to test more than daily. Let the FC keep coming down to 10 or 11 and don't let it get below 8 ever.

Congratulations!

@BigDave: Thanks again for your patience. Yes, the family was quite happy. It was a very splashy weekend…. and an incredible learning experience. As my daughter says: "You guys are awesome".

@FBU: pool stats (from this morning): FC=15.5 CC=0 pH=7.8 TA=150 CH=625

Congratulations!!!
Thanks for the test results but I'd really like to see your fill water numbers from your hose when you have time. All but CYA.

@FBU: got- it. hose water numbers: CL=0 CH=360 pH=7.4 TA=300 I'm reading about pool closing now- in the past never did anything but shock w/ 2 bags of powder, then let the pool guys blow out lines and shut everything down for the winter.

Did your closing method work?

[mary jo]

Not sure: My pool opened this spring w/ very clear water and so in that respect, yes….but that was pre-BBB thinking. Now that I know a bit more about my pool's chemistry and the FC/CYA connection, I know not to shock with the bags of powder so I'll use enough bleach to reach FC=30. I also wanted to find out if my high CYA needs to be accounted for in some way. I'm not sure what the CYA was last year or this spring because the pool guy told me not to worry about it- which I now know was a huge mistake.

Um, I don't see what the problem is. You threw in bags of...cal-hypo or di-chlor and it protected your pool over the winter. Did you test your water in the spring? If the #s were acceptable why change?

BBB is a way of thinking more than a set of rigid rules. There's a time and a place for Di-Chlor, Cal-Hypo and Tri-Chlor, as well as bleach.
