It's Great By Grey on 8/24/2011

Finally able to check something without mixing a bunch of chemicals. It's easy to use, and accurate. What more do you need? The only problem I had with my tester was that the tester flip top lid is very tight and difficult to open without using your fingernails, but I am sure it will loosen over time. I am just thrilled that about not having to pay 40 to 70 dollars for 25 liquid chemical phosphate laboratories anymore.
Great Product! By Chad on 8/24/2011

I bought this to keep my Phosphates in check since color card tests are inaccurate and VERY hard to read. I must say that I am impressed with the accuracy! Several tests on the same water sample resulted in the same numbers over and over.
My only real problems with the unit is the lid is VERY hard to open. If you have short fingernails or arthritis you make have problems getting the lid open. Another other problem is the reagents. I really wish they were in liquid form, it is hard to pour the dry powder in the tiny opening of the vial.
Finally the automatic shutoff timer of 2 minutes between C1 and C2 is much too fast! The powder does not dissolve quickly enough and you risk ruining the test if the unit times out. A more lengthy time period is needed here if dry powder reagents are going to continue to be used.
Other than these small problems the Hanna Phosphate Checker is genius!
Best phospate testing period By Richard on 7/30/2011

There is no other way to go. My local reef store recommend the Hanna, I ordered it, and there is no going back. Just be sure to follow instructions on keeping cuvettes clean, unscratched, and not introducing bubbles when testing. Standard test kits cannot be relied on, the Hanna is the way to go.
Love it. By Rick on 7/30/2011

This is easily the best piece of testing equipment I've bought in years, accurate to three decimals. 0.015 target.
Hard to know how accurate the measurement By Joe on 6/24/2011
Joe wouldn't recommend this product to a friend
This one is hard to know how accurate its measurement really is. I got different results even with same water sample. And of course that 3 min. timeout is crazy, lost a few package because of that.
More accurate and easier to read! By Dave on 6/16/2011

Since purchasing this checker I no longer need to ask my girlfriend to help match the colors of the test kit. My salifert test reads 0 when this reads .02-.04, which explains the slight algae problem I still have.
Way too easy! By Jonathan on 6/15/2011

Im so glad they finally came out with these kits! I hate checking my params but now its almost fun!Easy to read and fast as lightning.A+ all the way
much more accurate By Gary on 5/25/2011
Gary would recommend this product to a friend
phosphate test kit read 0 phosphates (too little color to see), but i still had some microalgae growing on the glass i had to clean off every few days. Switched to Hanna, i actually had .08 phosphate. Now i'm down below .02 on the Hanna, no more microalgae on the glass. Results speak for themselves, i'll never go back.

I have a tough time reading tests with color chips. This instrument makes testing quick and easy.
Simplify your life go digital By Robert on 4/12/2011
Robert would recommend this product to a friend
This has been one of my best moves yet. Takes all of the guess work out of the equation. 3 minutes and your done. LCD shows you clear and easy to read results with ample amount of time before the unit shuts off.
One thing though when you mix your reagent you gotta be quick you only have about 1 1/2 minutes to do so and set the checker. I find that shaking the vial vigorously and then slowly rotating it from left to right to remove the fine bubbles gives you enough time to get the vial in the checker and set the timer. I will be purchasing more Hanna checkers in the near future.
Great Tester - The devil is in the details By Nick on 4/9/2011
Nick would recommend this product to a friend
This has been a giant step up from the old testing methods I have used in the past. I have never liked the color charts and the math involved. When I see a chance to go digital I am normally first in line to give it a shot. I don't think the instructions or simplicity of the colorimeter could be any better! The only problem I have with the system is actually getting the reagent in the vile. I have wasted 2 packets so far due to not all of the powder making it in. After that I wised up and purchased a small funnel (one to put fluid in a flask) and it has been smooth sailing from there on.

i bought this item and am glad for the ease of use more accurate than test strips a tip for use is first step pour your powder reagent into a folded business card then you have it ready to EASILY pour it into vial
Great Tool but can be wasteful By Europhyllia on 3/18/2011
Europhyllia would recommend this product to a friend
I like this checker. It works well. But I wish I could change the setting on the auto-shut off to last longer than 10 seconds.
It takes 3 minute to process. If I get side tracked and pay attention to something else I miss the 10 seconds in which the result is displayed. Then I have to use up another reagent package and start all over.

Always had trouble reading those color based checkers. This test kit defintely takes out most of the guesswork. Still takes some work to check but at least you know you are getting a good reading! One downside - buying all the refills could get pricey after a while.

Great little meter. Do read through the instructions first to get use to the symbols on the screen and the timing. You don't have a lot of time (but it's enough) and you will get use to it. Do buy an extra set of test reagents. The test is so much easier to perform you will actual do it so those first 6 test won't last that long.
I actually store one of the tubes inside the checker to make extra room in the case.
If I had any downside I would say the clasp on the case seems a little cheap, I think over time it might have issues. But none yet.

Purchased this along with the HC GFO. Will NEVER go back to a color chart test kit. When we used our other test kits for PO4, we had to walk through the house trying to get good light for an accurate reading. Now, all I have to do is read the meter while sitting at the table. Super easy to use. Makes me want to test more often since it's so easy. Also purchased the additional packets of reagent since this kit only comes with 6. A++

I've been struggling with Po4 test kits since I've been reefing. This makes it easy. It costs about the same as two high end test kits but the precision and readability of the results makes it worth every dime.
