Calcium is necessary in plant and animal nutrition since it is an essential constituent of bones, shells and plant structures.

Hannah....OK
love this calcium checker, a bit pricey but far easier to use than traditional calcium test kits, I would recommend to all reefers

Great product
an excellent product, greatly facilitates the life of the aquarist, you no longer have to try to determine the color visually.

Quicker and more accurate!
Thanks so much for making testing fast and giving me a better more accurate reading! Love love love your products!!

Digital output is great but the instructions are hard to read and difficult to understand.
I like not having to compare colors but I still don't even know if I am performing these Hanna tests correctly. The print was so small I had to download a copy from their website just so I could read it. And to me the steps are confusing, sometimes you hold the button down and sometimes you press it but if you hold it down too long it turns off and you have to start over. I think it would be much better if you just press the button once for each progressive step.

Great Product
Would have given 5 stars, except for the reagent packages. They are difficult to get the reagent out without spilling some of it. Other than that, a top notch tester.westbourne

Not a good test device
This device is a huge disappointment. It gives me the same reading every time, which is unrealistically high. I monitor my parameters closely. I've used this checker multiple times. The results are always the same, and always wrong.<br>I really wanted this device to as simple and accurate as the PO4 and other checkers I have. It's anything but.
