Accurate, but... By james on 9/22/12

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.

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

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 8/30/12

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 8/17/12

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.

Slight Learning Curve but good overall By Andre on 8/14/12

I like this much better then looking at color charts, Just remember to buy some extra packets when ordering

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

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.
