The Hanna Checker is simply the fastest and easiest way to check my reefs phosphate. I’ve been in the hobby for over 15 years. As a reefer who is also legally blind reading test kits and colors has always been hard… This actually made my reef keeping life simple again!
no more guessing By r. wilmeth on 9/22/12
r. wilmeth would recommend this product to a friend
it is nice to be able to know for sure what your tanks levels are. for me there was a little bit of a learning curve and i used a lot of the reagent. you should buy extra reagent when you make your purchase. you do need to use caution opening the cap or you could break it.over all i am very pleased and glad i bought it.
Accurate, but... By james on 9/22/12
james wouldn't recommend this product to a friend
I absolutely loathe the reagent packets.
I wish it was a liquid reagent like the Hanna Alk, but unfortunately it is not. Instead (as another poster mentioned) you have to dump the contents of a small packet of powder into the hole of one of the test vials. It makes it a bit of a pain to work with.
Phosphate test, without a useless color to decipher By Keith on 9/7/12

I finally know what my phosphate is at, thanks to not having decipher a shade of blue, that looks diffrent to everyone that looks at it. Wish it came with more reagents but the refill kit is pretty cheap.
hassle to use due to manual dexterity By Join the Revolution on 9/6/12
Join the Revolution wouldn't recommend this product to a friend
Do not buy it. Go Salifert, or other means. This test would be a great if it was designed to work with ease. This test tries to be innovative ,but titration is much easier and guessing is eliminated. Who wants to pour a small pack of powder into a small hole the diameter of a dime???! The lid is difficult to open and the instructions are so 3rd world. Next..
Seems to work but cheaply made By Steven on 9/4/12
Steven would recommend this product to a friend
The meter seems to work fine, but be made of cheap plastic. The second or third time I snapped the lid open, it came off. It looks like there are only two small ultrasonic welds that hold the top part on. The meter still seems to work fine, but I have to keep pushing it back together every time I open the lid.

I just got this the other night along with the calcium test kit from hanna. The alk is a lot easier to test for and the reading was up to par with my other test kits. Only time will tell
Accurate and FAST! By Damian on 8/31/12

I cannot tell the shades of blue apart on the regular phosphate test kits, so the checker was an easy choice when it was time to get a new test kit. You won't be disappointed if you like to track phosphate.

I absolutely love my Hanna PO4 checker. Being colorblind I no longer have to bother the wife to compare colors for me. It's very easy to use and has always provided me consistent results. I'll never go back to the old way of testing PO4 again.

Essential By Robert on 8/23/12

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 8/17/12

This is so much better than trying to figure out what shade of blue it is on a color chart.

What an awesome product! LOVE this tester. By Chuck on 8/13/12
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 8/3/12
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.

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 6/18/12
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 6/17/12
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 6/1/12

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.

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!

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!

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.

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.
