TF100 Alkalinity test question

[brownie16]

When doing the TA test, am I looking for the drop to turn red, or the whole sample to turn red. My drop turns red way before my sample does. Also, if the answer is the sample, it goes to a "hot pink" color after so many drops.

TIA!

The whole sample should turn red/pink. It is important to swirl the sample to fully mix the drop before adding the next drop.

Like James said, the whole thing. Mine goes from green to grey to pink, and usually one more drop makes it a much brighter pink. Anything past that makes no difference. So don't stop too soon. But do be sure to mix thoroughly. Often I get a dull pink and keep mixing and it goes back to grey.

Accuracy and consistency is the key to a troublefree pool

Welcome to TFP!!

As James and Richard pointed out, keep swirling while adding the drops and don't stop counting drops until one more drop doesn't change the color. (this is where the Speed Stir really pays for itself )
