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!

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 9/22/2012

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 9/7/2012

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 9/5/2012

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 9/4/2012

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

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.
Love it! By BRIAN on 8/30/2012

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.

This is an essential tool for any reef keeper. Very fast and easy to perform tests.

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 8/16/2012

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.
