I've been using this product for a few months and the only thing I could suggest is that Hanna make a liquid reagent available. Accuracy is right on with Salifert test kit.

This is a huge step up from trying to read different shades of a color. I just can't wait till they bring out other testers
More accurate way of testing By Don on 9/28/2011

This unit is as close to lab results as you can get. Just 2 simple steps and wait the 3 minutes for the results. Much easier than matching a color to a card.
good product By Craig on 9/22/2011

I totally like having a digital read out instead of try to match colors like the other test kits, but the Hanna Checker is a little hard to use. You have to be able to open a packet with a wide opening and pour it into a very small hole, in a short amount of time. It comes with two curvettes so I started using one for the "zero" and the other for the phos reading. I still don't like the packets though, it's hard to empty all the contents without spilling reagent powder.

The Hanna Phosphate Checker is a great product that makes testing phosphate so easy and accurate. I tested the unit against another more expensive product and it was spot on in three different tanks. Can't wait to get my Calcium checker and then the Alkalinity...I hear they are also releasing a Magnesium checker as well.

This was the first hanna I tried. I now want every hanna test kit that is available. This thing is super easy and gives you such a pin point reading, no more guessing!

No faster than adding drops, but not having to guestimate or ask my wife what color is the match is far nicer.

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
Richard would recommend this product to a friend
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.

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

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.

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.
