Too difficult to use, wait for an upgrade By jamie on 9/8/11

First off, I love my pH checker from Hanna. I was hoping for the same ease of use from the calcium checker. However, it requires the use of testing water that is basically 0 ppm of Ca. Anything else and the test fails. Also, the requirement for the sample is to accurately measure 0.1 ml of your tank water and then one of the reagents is a powder. I would give Hanna more time to figure this one out before buying.
I would hold on this. By Dan on 9/4/11

it requires extremely pure water (DI/distill lab grade) and accurate measuring of 0.1ml (yes one tenth ml) of your sampl tank water. If you can get both right test will work. If your DI will have slight trace of CA you'll be way off.. according to Hanna even 2ppm of CA in DI is not acceptable. I would wait for Hanna address these issues.
Easy to use and gives accurate readings By Tom on 8/24/11

Easy to use and gives accurate readings. 2 things to note are:
- Requires DI water
- Reagent B is a powder
Not very happy about using a powered reagent, But other than that, I'm very happy with my purchase.
