Easier to read than others By Mike R. on 8/28/2010

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.
