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

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.

Super easy to use and accurate. No guessing with the digital read out. The next tester I need will be a Hanna.

Great BUT.... By BUG on 5/4/2012

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...

Much better than trying to match up shades of green. You won't mind testing now.
Throw out the color comparisons By thomas on 4/22/2012

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.

The instructions were confusing the first time I used it, but as soon as I figured it out it became the easiest test ever. I love the fact that it gives you an actual number. No more matching colors. Love it.

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!

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

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!
