So for 2 months now I have been doing the following thought it was right with our Hanna checker:
- 1 ml of reagent
- Fill to the 10ml mark with (I was using tank water)
- Zero out tester for C1
- Add reagent
- Test (I would get anywhere from 430-460)
Well today I stumbled upon a video and I guess you are supposed to do the following
- 1ml reagent
- Fill to 10ml mark with DI water
- Zero out tester for C1
- Add 100ul of tank water
- Add reagent
- Test C2
I did this method and got the same result I got of the prior measurement. How do you all test calcium with the hanna checker?
