Query: Worth Buying

This test kit was recommended to me by a few different people on various fish blogs and I must say that it has helped greatly. I am starting a new tank and am new to this but this test kit has made it so much easier to know what my test results mean and what I can do to fix any problems that arise. I highly recommend this over test strips since you get a much more accurate reading. It is easy to use and the color card makes it easy to interpret your results. I love how the booklet walks you through the process of each test, it tells you why the test is important, what your results mean and what you can do it your results come out negatively. I recommend this product to anyone who is seriously interested in the health of their fish tank.
