I have always hated test phosphates. I am color bind and have trouble comparing the slight shades of most test kits. This product solves my problem. Its well made and simple to use.
My only complaint is that it only comes with enough powder to do 6 tests. Otherwise, it's worth it.
Hope they make other testers. By J_T on 9/16/2010

This makes testing for Phos simple. The other test kits make it a guessing game. There is no guessing here. Follow the simple instructions, and there you have it.
I use both tubes, one for calibration, then the second has the reagent mixed in.
The only down side, that I hope they address for future kits, would be that you only have a few seconds to see the results, and then their gone.
If your buying this, also grab a refill of the reagent. 6 packets won't last as long as you think. Given how easy the test is to preform, you will find yourself actually doing them!

I was following BRS’s recommendation to change the material when I started seeing algae growth or had to clean my glass more often than normal. This worked pretty well but the checker is a pretty big upgrade from that. Now I can change it before I start to see more algae growth. The checker also allows me to use the GFO to max capacity and I am sure will save me money over the long run.

I purchased this tester to test the phosphates. I was using a Salifert kit, but like most test kits, there is a lot of judgment and room for error when reading.
The Hanna kit is easy to use. It is is simple as filling a tube, inserting it to calibrate, taking the tube out, put the powder in, then insert again. 3 minutes later it gives results. It has its own timer so counts down the 3 minutes for you.
An additional comment is it comes with a handful of powder to test, so if you want to test daily for more than a week, you may want to get extra powder.
