Fantastic Checker, really acurate and easy to use. The money seams steep, but the acuracy and ease of use make this a great addition to your phosphate fighting arsinal.

just received the phosphate checker and was skeptical that a colorimeter could be produced for sucha low price. Tested it on three reef tanks and results were zero. Thought the unit was defective, so waited all weekend and tested it on a freshwater planted tank in office. Three minutes later .91 PPM. Like a charm.

The best consumer phosphate tester by far. By NanoCabana on 6/17/2012

This is an affordable and accurate tester for phosphates. Like many, I was tired of trying to match color shades on a card. With Hanna's digital readout, I have confidence that my weekly test can be compared for trends. I also use this for my planted freshwater tanks and will buy Hanna's iron checker in the near future. Good job Hanna!
Easy and accurate test results makes this worth the price. By Moises on 6/17/2012

This Test kit is very nice because you get an accurate digital reading. If you are worried about your phosphate levels and want to make sure you have them under control you need this product. For the price of the test kit I feel like it should of came with more reagents to perfom test. As of now it only comes with 5 so you better buy extra refills. Only other complaint I have it the powder reagents is hard to get into the small vile. I would recomend getting this product with your GFO reactor.
Best investment! By Nicholas on 6/1/2012
Nicholas would recommend this product to a friend
If you are considering running GFO in your tank this is the way to go, This instrument is very precise and accurate. It is much nicer knowing exactly what your PO4 is rather than guessing it is somewhere under .25.

Great BUT.... By BUG on 5/4/2012
BUG would recommend this product to a friend
A cheap, flimsy, warped and very difficult to open case greets you when you first try to access this kit! Kind of like having a cheap and dysfunctional door handle on a fancy new car.... I hope this case is not indicative of the quality of the tester inside! Comes with only 5 tests, so be sure to buy more when you order one of these.
Other than the above, seems to work great and consistent and is easy to use once you free it from the cheapy case...

I hate reading color charts. I never feel like i know for sure what the result is and the time involved sucks. I am a zoology major in college and I bring my checks with my to labs and they professors are even impressed. the liguid reagent is slighty more conveinant than the powder but both are easy to use and the results, well who doe not like looking at a number that is plus or minus a few ppm andknowing for sure what the result is

I have nothing but good things to say about the Hanna Phosphate checker. For a while, I was using color chart comparison phosphate kits, which is extremely difficult since the shades of blue are so subtle to compare. Added to that, the lowest value it read to was <.25. For delicate sps tanks, less than .25 is not an accurate enough result. This is why the Hanna checker is so nice. It gives decimal values all the way down to .01, rather than a blanket statement of less than .25. Considering the money we spend on our aquariums, phosphate should be measured accurately to ensure animal health. Considering it's only about double what other kits cost, it's a no brainer! Skip the guesswork, and get this checker! It makes testing to much easier. Don't forget to buy the reagents when you buy the kit!

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!
Would buy again! By Alex on 2/2/2012

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

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...

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.

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.

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.
