What would be my next best alternative? I've had great luck with standard bleach over the years but due to pandemic this year, it's hard to come by.

Got it. Thanks!

So I will take this that if my cya reading on two different tests prior to slam was 45 and then 40 after removing and adding water, I should not worry about tests I did after starting slam that indicated much higher cya. Guess I should have just not run the test "for fun" after the slam had...

You can also get a 50ppm CYA standard solution (from TFTestKits.net) and use that to calibrate your test procedure How is this different than the CYA testing I am using as part of my TAYLOR TECHNOLOGIES INC K-2006 test kit (testing using the .5 method)?

Actually when I got my initial CYA readings (45 and then 40) I had almost no FC (it was really hard to even get the reagent to turn even light pink and a single drop took me back to clear). From what I've read in the forums, having an CYA as high as it appears to be now would take a HUGE amount...

Okay tested CYA and FC again today (had a pretty heavy rain last night so had to drain some water). As expected with the rain, FC dropped from 16 yesterday evening to 11 around noon today. CYA dropped from almost 90 yesterday to around 80 today. Made sure I was testing properly. Still...

Will do... curious, is it correct that if my CYA were really that high, I'd see much slower rate of depletion for FC?

Right! One more question... two days prior to SLAM I showed a CYA of 45, removed some water and refilled. CYA came down to 40, so I thought I was in a good position to begin the SLAM (started yesterday). I've gotten my FC up to the target of 16 (for about 18hrs now) using 8.25% bleach. So...

Thanks! Was wondering about that. Amazing that i have so little considering how much i added over the last week prior to starting the slam process. Using store bought "shock" treatments, I guess I wasn't giving it enough to overpower everything that was in my pool? So I never built a reserve?

New pool owner (came with the house). I'm not totally sure what I am missing here, but hoping someone can help. Using the Taylor K-2006 kit. Testing Chlorine using FAS-DPD method (and watched video on how to do it). Testing using the .2 ppm method for sampling. When I add R-0870, I cannot...
