Do you guys use to water to 0 in your Hanna checker when it says c1 or tank?

tank water

Can I use ro or will that throw it off

 

[lapin]

RO wont work. It needs a base setting of tank water to start. Then add reagent and the color will change in the water sample. Then it reads the difference

Thats for the calcium checker, for the alk and phos checker you use the tank water then add reagent

Hanna checkers Alk and Phos
You turn it on. (press button) When its ready It says add C1. You place the vial of tank water in the checker. Close lid. Press button. When ready it will say add C2. Take the vial out add the reagent, mix or what ever it says. Re-insert the vial. Close lid and press button again. Wait for final results
