I have the API liquid test kits for both GH and KH, but after I tested my water I ended up with more questions than answers. My current GH is 20 degrees/358 ppm and my current KH is 9 degrees/161 ppm. Both of these seem high to me, but I am not 100% sure what these number mean and how they work. Is this within what would be considered an acceptable range? If it is not, then how do I go about changing these values? Thanks!
