I went to Mobile Alabsma today, bout an hour from my house to a LFS, all I bought was a Ca Profi Test kit Calcium from Salifert. I got home and was going to use the kit tonight before I did my 15g water change tommrow and the kit is missing one important piece, the little measuring spoon for the Ca-1. If anyone else uses this kind of a test kit, is it possible for you to give me some idea on how much of this powder I need to use? I have one of those tea spoon measures my wife uses in the kitchen, well, not really, I use them, the wife don't cook, I do all the cooking. It has diff. sizes from 1/4 tsp up to 1tsp.
