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 8/17/2012

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.
Slight Learning Curve but good overall By Andre on 8/14/2012

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 8/13/2012

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.
Great Checker well worth the green By Andy on 7/3/2012

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.
