I got free Calcium and Alkalinity tests from Habib @ Salifert at MACNA and have been afraid to use them since the first time I tried

It wasn't that bad! lol
My Calcium tested right at 420 and my alkalinity at 8 dkh.

Are these pretty good results? I think I may need to get my dkh up a bit...

Also, I am interested in getting new test kits for everything and Im curious as to what other people are using, especially Mg and K+
