taylorR-0013 Cyanuric Acid Reagent (2 oz) (Pack of 3)

Works as intended. Will order again.

I needed to refill the reagent for my test kit and this is exactly what I was looking for. Excellent product and quick delivery.

Was like water used all 3 bottles nothing registered on spa stick

Is a chemical and it must be correct because I get good readings. Can avoid buying a whole new test kit a bit longer since this is the only chem I used up.

I trust the Taylor Tech products. I am the self appointed pool person, and these reagents make it easier. It is the only brand I use.

Bad pool water, it was easy to use and worked well.
