My P.O.P. is gone. need help again

[shub_31]

ive tested cya over and over and its no more than 100. All the kids do use lotion. And im 100% sure I have not added bromine. I just shocked again at 730. No ones been in the pool since 2. Ill check around 830 and check in the mourning. Hopefully no drop. I want to make sure I dont have algae even though Ive never ever seen any other than having a cloudy pool. And like Ive said before, my pool is the clearest its been in a while. Thanks.

To test the way I said, you'll have to keep people out all day Monday and Tuesday till noon, retest Monday night and Tuesday AM and noon.

Just tested.

Last night: FC 23
CC 1

This mourning: FC 23
CC 1

This is the first time Ive had no decrease in FC since all the advice I had been given way back. ill see what happens then test your way if I still have problems. Going on vacation next week so no one will be in the pool then. Thanks

tested again.

This mourning FC 23


4:30pm FC 13


No one in pool all day, fairly sunny with some rain. Seems like a big drop for 8 hours.

I'm going to ask Chem_Geek to look at this, but the only two explanations I know of for this are:

#1 - Your CYA is not as high as your testing is indicating, OR
#2 - There's bromide / bromine in your pool (or iodine, though I don't know how that could be.)

Meanwhile, please read this page:

Ok. I've talked with Chem_Geek, and his thoughts confirmed mine. Add your second set of no-sun readings that pretty much eliminates possibilities other than the ones I mentioned.

But . . . Chem_Geek noticed some things I hadn't about the way you described your CYA testing.

So

#1 - K200x CYA testing is turbidimetric: the water gets CLOUDY when CYA is present.
#2 - You fill the small sample bottle to the first line with pool water and then add CYA reagent to the 2nd line.
#3 - Shake, wait 15 seconds, shake again, wait 45 seconds.
#4 - Then, carefully add this mix to the small CYA tube side of the kit, adding slowly, till the black dot disappears.
#5 - Stop adding when it disappears, and read your CYA level from the outside, matching water level with the marks.

BUT . . . if you the mixed sample water doesn't get cloudy, you have little or no CYA.

Well, Ijust got back from vacation. No testing for 7 days. Heres what happend. Had a neighbor add bleach every day and the pump was running all the time with solar cover in place.

Sat. Rained all day. Removed 2 inches of water, tested then left.

Sat FC 15ppm
Sun added 3qts 6%
Mon 6qts 6%
Tues she forgot
Weds 3qts 6%
Thurs 6qts 6%
Fri 3qts 6%

I got home sat at 1pm. Tested
FC 7ppm
CC 1ppm.
I really expected FC to be much higher with cover on and no swimming.There was about 1inch of rain added over week. Then I added bleach tested at night. FC 12ppm. This mourning it was 9ppm. Something isnt right. Im gonna test my cya again. I really dont know whats going on. i thought we had it under control.

[PoolDoc]

Let me know your CYA level AND your water temperature, please.
