I like Hanna Checkers, but the accuracy on this one doesn't seem up to par. By Chad on 12/15/2012

I am a fan of Hanna Checkers, but my Calcium checker doesn't seem all that accurate. It is ~25-100 off from other test kits and I follow the directions meticulously.

I was hesitant about getting this tester as I have read some questionable reviews, but using it for almost six months now I love it. It is consistent, as long as it is used correctly with DI water. It is nice to read a number rather than judge a color.

Out of all the test I like this because u don't have to count drop by drop, super easy
Accurate if use good water By Edward on 9/28/2012

So I knocked off a star because this should come with its own DI water (or BRS should sell the Hanna water). If you use the lab grade water, this thing is very accurate and easy to use. I can't say it is any better than Salifert, but having the digital readout is a plus. The one other thing I wish it came with was a little cloth to wipe the glass before putting it in the checker. I have one to clean glasses that I use and I think it would be easy to include that since the clarity makes a difference (same as all other Hanna Checkers).
Worked for me By MATTHEW on 9/24/2012

I found that I was getting accurate results if the directions were followed precisely. Not as easy to use as the alk tester.
Test Results way too high By Bob on 9/11/2012
Bob wouldn't recommend this product to a friend
I've used this Ca Checker for several weeks now and can only conclude that it consistently measures the Ca concentration at least 100 ppm too high. I was really hopeful for this instrument but very disappointed. Going back to my Salifert kit that I can believe and trust.
Works for me By Christopher on 9/1/2012

I just got this the other night and although I will agree it is a bit hard to measure out some of the steps, it does work and the reading was up to par with my other test kit. Only time will tell.
Highly recommend. By BRIAN on 8/30/2012

The Hanna calcium checker has worked great for me. I always get consistent results. It's simple to use with just a few steps to follow. No more trying to guess colors. Just make sure you have some fresh RO water on hand to use with the test.
Do Not Buy By Robert on 7/21/2012
Robert wouldn't recommend this product to a friend
I cannot believe Bulk Reef Supplies sells this product. It is horribly inaccurate. I bought this tester and wish I did a search on the internet before I did. Like myself, many others find this tester to be a total waste of money. It simply does not give accurate measurements of your tanks Ca levels.
Not That Great.... By Derrick on 7/7/2012
Derrick wouldn't recommend this product to a friend
So I have the phosphate and alkalinity checker from hanna and both are wonderful. Easy to use and accurate. The Calcium checker on the other hand is VERY difficult to use and usually the numbers are not even close. I think you need to have lab grade RO water and a specific instrument to measure the .1 ml of water. Hanna needs to make this easier to use somehow. My salifert and red sea test kits are so easy to use I would recommend those over this unit.
Terrible product By Francisco on 7/6/2012

Be smart, due diligence and read the reviews posted here. In its present state, this tester is not reliable enough to rely on. Distilled water?? Powder?? .1 ml ?? Go Salifert or Elos and be done with it.
Not so precise! By Benjamin on 6/18/2012

It's innaccurate. It works, but it's innaccurate. And I've done research in genetic labs, its NOT the user on this one...

I found tat the API calcium test was less time consuming, and pretty effective. I won't reach for this kit as often as I thought I would.

I see lots of reviews on the challeges of using this tester but is not that hard at all just follow the instructions and you will have accurate instant results. throw out that color matching junk and get with the new world of digital readouts

Never got an accurate reading!! Always had either a flashing 600 meaning cal levels were over 600 or L.lo meaning low light......
Simple and Accurate By Rod on 3/29/2012

The bottom line is this is a great test kit so long as you read and understand the directions. Double reduncancy testing on several separate occasions have proven it accurate and cosistant.
