Not as accurate as the HI-376 By Steve on 12/26/11
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.

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 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

I wish I purchased this product before wasting my money on impossible to read color tests. Well worth the money. Best upgrade I've made to date

This is soooooo much better! I really like the digital readout. The test instructions are very easy to follow.
Be careful opening the test unit for battery installation, make sure to pull the battery door out straight and do not pry it to one side.
Hanna Checker Phosphate PO4 Colorimeter By Virgil on 11/27/11
Virgil would recommend this product to a friend
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.

Extremely easy to use and amazingly accurate. Absolute must for phosphate control, great to check your top-off water.

it is costly, but i am glad i got it, it is very acurate, and easy to use once you manage to dump the packet in the cuvature.

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.
Finally something easy By Brady on 9/29/11

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 9/29/11

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 9/22/11

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.
5 stars! By Jeff on 9/21/11

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 8/24/11
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.
