Like the checker - easy to use, prefer liquid reagent rather than powder.

No more guessing the colors
They give you reagents
Love the simpleness once you figure out how to do these
They shove everything into the case and if you don't put everything back just right it won't close correctly
The instructions aren't as clear as they should be, so i just googled and watched the videos on how to do the tests. The terminology of unreacted sample and when you think about it, on some of these tests, it makes you go huh? So watch the videos.
The battery cover is a pain to get off
Overall so glad i bought these.. no more test kits to expire and trying to distinguish different shades of blue!

I have been using the other test kits out there for a while and decided to see if the Hanna checkers were worth it.
I LOVE them and wouldn't go back after trying them. The digital readout is easy to get and accurate.
So much easier, don't hesitate to pick up this product today!

Finally an easy to use easy to read phosphate meter that doesn't cost an arm and a leg. I have tried different brands in the past and all the results were very hard to read. This unit reads it in digital versus me trying to read the colors which are usually very faint. I would recommend this Phosphate meter to anyone looking for a simple to use accurate reading.
Very happy By Aaron on 1/22/2012
Aaron would recommend this product to a friend
Wow, this product is outstanding. No more reading shades of blue. It's accurate down to 0.01.
The only complaint I have is that you have a 3 minute time limit to mix the water and get the bubbles out., just to save the battery. The first time I tried this, I didn't make it in time. Be sure to have your reagent packet open and ready to pour. Also, limit yourself to the recommended 1.5 minutes regardless.
Good tester By bobby on 1/22/2012
bobby would recommend this product to a friend
I like the Hanna phosphate tester, you will need to be quick adding in your Reagents into your test tube because the monitor will turn off automatically and you will waste Reagent. I had issues with the monitor readings not reading correctly a couple time but overall this is a good tester get it I lover it. Overall the price at BRS is cheaper, the Quality is top of the line they really know there products and there knowledge is sure impressive they do there research too that’s why I love to shop here Shipping is super fast.

I was surprised when the tester arrived there was only enough reagent for 4 tests???
Would have been nice to know that when I got it so I could have ordered more.
there was some plastic ratteling around inside of it and whatever it was fell out while installing the battery. the unit didnt work to find out that the supplied battery was dead.
replaced batter, works like a champ!
easy to use, easy to read...
I think Steve has a valid point in his review 12/26/11

Not as accurate as the HI-376 By Steve on 12/25/2011
Steve wouldn't recommend this product to a friend
I wish I had done a bit more research about this before buying it. This Hanna model (HI-713) has an accuracy of +/- .04ppm when target levels for phosphate are usually considered < .02ppm. I would much rather have purchased the HI-736 Phosphorus Ultra Low Range Tester by Hanna. Too bad BRS doesn't stock both and explain clearly the difference between the two.
Poor Quality Build By AJ on 12/20/2011

I've had this for about a year, but only used it about 20 times. It broke due to a manufacturing defect. The Hanna customer service would not stand behind their product. Despite the defect, they indicated warranty was only 6 months and they wouldn't do anything.
Fantastic By Brian on 12/20/2011

Fantastic product, no more trying to compare colors with those horrible color cards. The only down side is the powder reagent, hopefully Hanna will develop a liquid reagent.

The Hanna Checker Phosphate PO4 Colorimeter is very easy to use and only takes a few minutes to make sure that your tank is where it needs to be! I have spent so much money on frags, fish and equipment - the cost of this item is well worth it! Make sure to add the extra packets to sve yourself from running out.
I plan on getting the other Hanna checkers for my tank

Loved this tester. No more other test for me. The digital read out makes it soo much easier. I'm getting the calcium checker for Christmas I liked this one soo much. Thanks for providing a great product. Just read the instructions and maybe review a youtube video on using it. The system has a timeout and you need to complete all the actions within a certain amount of time, but there is enough time if you are prepared.

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
Craig would recommend this product to a friend
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.

It's Great By Grey on 8/24/2011
Grey would recommend this product to a friend
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
Chad would recommend this product to a friend
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!

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.

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.
