Numbers look OK, but still a bit cloudy - results in post

Yes that was exactly how I performed the test based on the info on this site. I am performing it now with diluted water and will report back!

I just did it with 1/2 pool water, 1/2 tap and at 60 the dot disappeared making my CYA 120! Now that sounds right!!! I need more FC if this is the case.

So doing the CYA test. I slowly added the water...waiting for the dot to disappear. At one point (80ish) I thought it disappeared but if I waited a second and killer squinted and strained my eyes I could still barely barely barely see the dot. Am I wanting to go past that point untill I 100000% cannot see the dot anymore or should I have stopped at 80?

Thanks everyone!!!

You can repeat the test by pouring the sample back into the dropper tube and trying again. Really it doesn't much matter. Your pool's CYA is 120 to 160 that puts you in the same bracket in the best guess chart. It's probably time to shock the pool.

Bring the FC up to 25ppm with bleach and keep it there until one day after these three criteria are met: 1) Pool is clear; 2)The pool loses less than 1ppm FC between sunset and sunrise; 3) There's 0 or nearly 0 (one drop - 0.5ppm) CC.

Great, that was exactly what I was going to ask!! Off to bring it to shock level now. Thank you so much for all the replies!! :-)))

I agree with Dave that whether your CYA is 120 or 160 is irrelevant because the needed chlorine levels would be the same in either case. But, just for future reference (or for anyone else who may be reading this thread), this may help you with the CYA test:

Thanks watermom! I had checked out that link before doing the test. I was apparently just overthinking it. In that last picture I feel like if strain hard I can baaaaaarely still see the dot (which was what I kept doing on my own test).

I know for this partiuclar case it didn't matter if it was 120 or 160 since they were the same shock level. Just thinking about if retest awhile from now what I'll be looking for.

Thanks again!!
