Easier way to test for high levels of chlorine?

[Mandy M.]

Hi! I need to drain some water out of my pool because my CYA is way too high (120 was my best guess testing today, and Leslie's said it was even higher). That said, until I drain, I need to maintain higher chlorine levels. I did the FC test today, but didn't feel super confident in my results. Plus it was cloudy, which made it harder to tell. The small kit only goes up to 5, and I need to be between 9 and 13. Any other way to quickly test?

P.S. I am obviously new at doing this on my own. Lol.

Why wouldn't you just go ahead and exchange some water to get the cya level to the proper range? You don't want to have your cya that high because it can lock up the chlorine.

If you get a good test kit then you will be able to test the chlorine up to approximately 50. You will also no longer need to be going to the pool store because you can do the testing yourself instead of someone who may not have a clue how to properly test.

I see a TF100 kit with a fas dpd test in your NEAR future. You can also buy that test separately.

TF-100 will save you a fortune by NOT buying whatever you've been putting in to that pool up to this point.

Our swim season will be over when I do the drain, as the water will be colder, so I wanted to wait a few more weeks.

I do have the TF-100 kit. It just seemed subjective as to how many drops are needed to get it "perfectly" clear. Then it turned pink again after sitting.

I'm sure hoping!

I have one. Which test is that? I only have the FAC. And I thought it seemed pretty subjective as to how many drops it took to be "perfectly" clear.

It should look like this...

It should be bright pink when you start. Add drops until it goes clear. If in doubt, add another. If it didn't change things, subtract that last useless drop. Just that easy. Ignore it turning pink after it sits. Just run the test at a comfortable pace. You don't need to rush, but you also don't want to dawdle and have it turn on you in the middle of the test, either!
