I just switched to a liquid based tester from strips.
I'm fine with testing clorine and ph, but I'm really confused about Total Alkalinity.
The instructions say to add the initial drop(s), then count the drops of another type until there's a "permanent color change".
What does that mean?
I tried it and had a purple color, initially. I kept adding the other drops and finally the solution turned clear. I'm really confused.
