I was able to find instructions on another fish forum. Apparently you have to email API and a couple of folks said they hadn't had success with that and someone within the forum was able to produce instructions.
So I did the tests.
KH = 9
GH = inconclusive. I stopped adding drops at 45 and it still hadn't changed from orange to blue! So I figure either the test is defective b/c it's old, or my water is really hard. The instructions do not include any kind of "scale" so I don't know if 45+ is a possible reading. As I mentioned above, I know we have very hard water here.
So what do you think? To refresh your memory, my pH is 8.2 and I am looking for suitable fish to go with my Red Eye Tetras in my 29 gal. Thank you.
