Thanks Tim. I had a feeling that test was junk, so it wouldn't surprise me. The water is very clear. 4-5 tablespoons is probably about right, maybe a little more. I guess when I saw the pH so high and the kH had fallen a little I assumed. Now I wonder if the pH test was even accurate :unsure .
I need to get hold of some better testing equipment like Matt said. In the meantime I'm going to watch everything and figure out a way to get an accurate reading on the Calcium and not dose any kalk until I figure it all out.
Thanks everyone for all your help. Now I'm starting to lean toward that little sailfin just not being healthy for some other reason.
