Total alkalinity test question

[TBK]

I have a question regarding the total alkalinity test in the TFTestkit.
At the R-0009 one drop at a time (continue until color changes to red). Is that until it stays red or when it first changes to red, when using the Taylor speedstir, it turns red around 12 drops but then changes back to green, latest test it stayed red at 21 drops. Look for some clarity. Thanks

Welcome to the forum.
You go until the last drop creates no color change. Then subtract that drop.
Sounds like your TA is 210 ppm.

Thanks mknauss, I just wanted to be sure, water level is a little low, so adding fresh should bring that back down a bit.

Depends on your fill water chemistry. Why would your TA be so high?

I had just raised it, too far I guess.

I would say.
