i got bought this cheapo $10 calcium test kit and got home n tried it out and it just seems like such a pain 7 drops of bottle 1, 3 drops of bottle 2, and 1 drop at a time of bottle 3 shaking the vile each time till it turns purple (20 times ) so i guess it looks like its on to the next lfs but does anyone know of any better test for calcium??? what type of test does everyone else use for calcium??
