Chlorine and cya levels

[Daddydave]

The last 2 days I have noticed no chrolene in the morning checking my pool.
Had been using about 30 liquid ounces a day.
Check cya 2 days ago thinking maybe no good.
But I'm between 40 to 50 ppm.
Black dot test. Possibly gone at 50 for sure gone at 40.
I'm using tf-100 kit.
Pool is roughly 13500 gallons.
Heat has been high the last 2 days.
I checked in the evening I'm at 2 on chrolene and added another 15 ounces.
I will check again this evening to check again.
Ph is 7.5 at the peak of the heat today.

Is there a question in here somewhere?

If your CYA falls between 40 and 50, round up to 50.

Use the FC/CYA Levels chart to determine the correct FC target range for CYA 50.
Dose chlorine to the high side of the target range.
You never want the FC to get down to minimum.

Since you reported that FC has been low or zero, dose FC to high side of
target range and do an Overnight Chlorine Loss Test.
If you don't pass the OCLT, you need to SLAM Process.

Been trying to see if I have a loss or not. The problem is I'm checking in the evening and my wife checks in the morning. I get busy with work and she doesn't report out what it is in the morning. It sounds like I need to make sure I don't loose 1 ppm from night to early morning.
I did not ask the question I was just posting to make sure my cya level was good. I'm trying to get good test results to know what I have.
I tend to over think and my wife Just wants add chrolene and not test.
Thank you all for the help

I checked in the evening I'm at 2 on chrolene and added another 15 ounces.

15 ounces of 10% will raise FC by .9, 12.5% by 1.1. No where near enough to get you back in range.

Treat your CYA as 50. CYA of 50 is just fine. Never let a test result be below target range. If you have to dose higher so your FC is in range when you test, so be it. Link-->FC/CYA Levels

Honestly - the same person needs to do both the evening and morning tests to minimize any testing errors.
Slight differences in the way you each test will alter the results. Normally this isn't an issue - but during an
Overnight Chlorine Loss Test it can be an issue.

Be consistent and methodical in your testing.
