I'll bet you smelled chlorine when your husband went in the pool and when he came out. That's because any impurities on the skin get metabolized and...smell like "chlorine".
Happens to me all the time. My FC will be solidly where it needs to be, there will be NO "chlorine" smell, I'll just stick my arm in and Bam! "Chlorine Smell"!
I think it's time to let it drop.
I haven't tested enough to be certain, but I suspect that, when FC levels are very high, spurious CC levels may appear. If your FC is stable overnight -- and 2 ppm is fairly stable.
There may be some lingering chlorine demand. However, the best way to deal with it is probably simply to run FC levels equal to 10% - 15% of your CYA for awhile.
Black ring around the skimmer can be from body oils and lotions OR it can be from plasticizers being released from the liner. If it's plasticizers, there is NOTHING you can do about that, except keep the pH reasonable (between 7 and 8).
OK- I just tested this morning @ 6:30am FC=26 CC=1
Lost 1 ppm FC overnight (27 to 26)
So if my CYA is 150 then I should let the FC lower to the 15-22 range and keep it there, and not worry about the CC? What if the CC level goes up?
Sounds right.
If CC goes to 1.5, wait for it to come back down. If it continues climbing - it may take additional action. Let the pool get all the sun it can.
Ok- so by wait you mean do not add any bleach, just keep testing and see if CC goes down ( or stays at 1) at lower FC level, yes?
Yes. That's what everyone here has been telling you. Please re-read Ben's last post, above. He's said clearly that you need to let FC drop to 10%-15% of CYA and leave it there.
So if CYA is 60, FC should be between 6-9ppm. If CYA is 90, FC should be between 9 and 13.5ppm. Etc.
THEN see what happens to CC.
got it.
Also, you'll need to avoid focusing on problems you do NOT yet have. Just do the basics, and worry about the other stuff WHEN it becomes a problem; not before.Quote:

Wow indeed- I heard 70 mph winds in the area. Incredibly, we only got a bit of rain, but closed the cover to be on the safe side.
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.
