Fast Testing by JOEL GREEN

Comments: Nice test kit. One of the quickest out there to use. Just to comment on the previous rating, the results are to be read between 5 and 30 seconds per the instructions. Always calibrate any test kit with a known sample in solution to confirm it's readings. This even applies to very expensive high end kits. Yes, I would recommend this product to my friends.

Unsatisfactory

Phos test by MARK BELLAMY

Experience Level: Intermediate

Comments: This test is all over the board. If you let the test sit for 5 minutes it will change colors constantly. Even the sample water that comes with it that is supposed to be at 1.0 reads at first 0.1 and changes color from there over a span of 5 minutes. Don't use this test - accurate readings seem to be impossible. I would not recommend this product to my friends.
