This test kit has a very clear endpoint, making the test very easy to use. However, because freshwater aquaria have so little calcium (and GH) usually, the accuracy of the test is suspect. The PPS method of growing plants tells us to double the sample size to compensate. However, this fills up the test tube almost all the way. I usually measure the sample with the tube, then pour it into a glass container of some sort. I\'d also recommend you make a second sample without adding any of the #3, to compare the color. This way you can be sure you have reached an endpoint.
