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.
