Shoot! I tried a calcium test before and I swear it was a joke. You do little drops, add some powder or something and then look for a difference in color. Always looks clear. I mean, you can't with the naked eye tell a difference with any accuracy between clear and the 20 different shades of blue which will determine your level. I forget what brand name tester it was.
I forgot where I read that the lime has something "undesirable" in it, but I wouldn't hesitate to use it if I knew what I was doing.
So, I should measure my "Alk
and my calcium"? Any suggestions as to what a good/reliable kit? I am still interested.
Thanks for your replies.
