"To test the water, you have to put it into test tubes and add drops of test solution into the tube. Then you have to wait sometimes up to 3 minutes to see any results and then compare the tube to the color charts. It is a HASSLE to dip each individual tube and then drop the solution (some of the solution even has TOXIC warnings and the directions tell you to wear protective gloves and goggles...) in them then WAIT.
Also... don't forget that this product is being sold for over $30.
Unless you want to pretend your some sort of mad scientist, then just look for test strips people. Their MUCH MUCH easier, CHEAPER, and just as accurate."
