Essential By Robert on 8/23/2012

I have the low-range phosphate colorimeter.
Upon receiving, I opened the top of the unit and the entire top white part separated from rest of the body (the small plastic pins holding it sheared away)--a rather inauspicious start. It is still usable and I don't want to screw around with returning it--despite BRS and their excellent return policies.
I just have to hold the white part against the rest of the body and it works OK.
WATCH OUT for the regent. Use a scissors and OPEN CAREFULLY! This stuff has a very low PH and will irritate skin noticeably. In addition, the reagent is a little tricky to pour out of the envelope which can increase risk for accidental spillage. Again, use care with this reagent.
Other than questionable quality or quality control of the physical unit and the nasty reagent, I cannot possibly imagine living without this essential instrument.
Good tester, need more reagents By Mark on 8/17/2012

This is so much better than trying to figure out what shade of blue it is on a color chart.
My only complaint is that it only comes with 6 reagent packets.

What an awesome product! LOVE this tester. By Chuck on 8/13/2012
Chuck would recommend this product to a friend
For anyone's who's used the 'other' phosphate testing kits, we all know how crazy-difficult it is to read which super-duper light shade of blue the result is to get a phosphate reading -- basically inaccurate/impossible and something I stopped doing often because it was a waste of time. NO MORE! After getting the Hanna phosphate checker, it completely takes the guess work (and eye-straining) out of phosphate testing. I almost feel spoiled having the digital read-out of the phos level after struggling with other test kits for years. This is one of the best and easiest tools, along with a nice refractometer, that I have for my 240g mixed reef. And with this low of a price tag, it's a no-brainer that every aquarium owner should have one.
Fell apart after 3 uses By Nathan on 8/3/2012
Nathan wouldn't recommend this product to a friend
Don't get me wrong, this thing is easy to use and works great, but it fell apart after the 3rd use. The top detached from the base so now when I use it I have to try and hold the top on so it doesn't fall off. I have tried to contact Hanna about this issue two separate times and have received no response.
It works great and I understand you run into issues with products from time to time, but receiving no response from a manufacturer is unacceptable.

Extremely easy to use! Test kit is simple and accurate. I tested it versus my salifert and red sea kit and the test was on the mark I did not need to look at silly color charts. GREAT PRODUCT. Now if only hanna can make it for other parameters and fix their calcium checker.

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.
worked like a charm By David on 6/26/2012

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.
Very accurate By Benjamin on 6/18/2012

The best consumer phosphate tester by far. By NanoCabana on 6/17/2012
NanoCabana would recommend this product to a friend
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
Moises would recommend this product to a friend
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

This product is very simple to use. I love the digital display no more guessing. I recommend it to anyone who needs to test for phosphates. I bought dry rock and wanted to test for leaching phosphates and this little tool made it easy.

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.
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.

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
