tested 10 times got ten different results using 0 tds r.o. water called hanna tech support guy told me it was too difficult to use and he himself would not use it on his own reef tank!!!!!!! This coming from the hanna tech himself I wont mention his name...... Then he sent me the "other" intructions not included with the unit still did not check consistant,, but better than at first. My salifert will give the same results time after time. This test kit will sit and collect dust being I cant return it !!!!!!!!!!!!

Not accurate enought to be useful By Actuary on 2/22/12

I am a big fan of some of the other Hanna Checkers - primarily alkalinity and phosphate. However, they really missed the mark with this checker. Not only is the test rather complicated compared to the others, it is highly inaccurate. I should have looked at the specifications where the accuracy is stated as +/- 6%. I purchased it to try to get an accurate daily calcium uptake in my SPS reef. When you get consecutive readings which are 50 ppm apart it is essentially worthless. Stick with a good titration test kit such as Elos or Salifert until Hanna makes some serious improvements.
Another Good Hanna Coloromiter By Roy on 2/19/12

While I did not buy my Calcium Colorimeter through BRS(and paid more), I am very happy with it. It is a little more complicated testing procedure than their other Colorimeters but I've found it to be accurate. I also use distilled water for the test and make sure to be very accurate with all the measurements. It's much better and faster than doing a titration test to determine Ca levels.
Unreliable readings By Eric on 2/12/12

I have the other Hanna checkers and love them, but the results on this one are all over the place. Complete the test multiple times and you will get a wildly different result each time. I now use the Red Sea Coral Pro Calcium Test Kit.

Confidence inspiring By Ken J. on 1/21/12

I am a novice in this hobby, but not with meters. We use a number of Hanna professional products at work and I was pleased to see that they made "hobby grade" instruments for aquarists. They don't display the build quality of a professional meter, but they don't cost hundreds of dollars either. The case, while durable, is clearly a cheap product. There are a hundred chinese shops that can produce plastic cases which close properly. But you are buying a meter (not a plastic box) and the price is right for this one. I would not think twice about the purchase. The Ca checker is more complicated to use than the other Hanna checkers, but that is a function of the test, not the meter. Buy it, adjust your levels with confidence, and get back to watching the corals.
Good product By shane on 1/20/12

Works great as long as your RO you use for the test is 0 ppm but on the up side it is really acurate and only paying 9 bucks for the refills is way better than paying 40 bucks for a new test kit every time it runs out.

I really like the digital readout and the test instructions are straight forward and easy to understand. One of my 1.0ml syringes was labled in reverse which confused me.
I'm not a big fan of the little packets of reagent, they are a PITA to pour into the vials.
Still, far easier to use than other test kits that I've had in the past.
Works great By Jose Manuel on 11/25/11

I had a Salifert test kit but it wasnt accurate enough. It read 370 on freshly made SW, tested 4 different salts with the Salifert and the same. Got the Hanna and it reads what the Salt manufacturer says it should be. Excellent product.
Another great checker from Hanna By lachapr on 11/24/11

This is my 4th checker and I love them all... I would recommend that anyone that is having issues with checker to watch the video that Hanna has put out. It is super easy to use and very accurate in my testings.
Most Compliated Hanna So Far By David on 11/22/11

I have other Hanna Checkers..this one took a bit longer to get in the groove with. It does require RO/DI water but if you dont use that you will have other problems anyway and will also clearly need the phosphate checker! The nature of the science behind this test makes it more complicated. I believe it is worth the steps and carefully measuring out the small sample size. Just follow the directions and its a slam dunk.
