For some time now, i have been interested in trying Zeovit, but the task seemed to costly and tedious to me. Then I heard of the Vodka system and did a little research. It is similiar to the Zeovit system in the way it acts by using bacteria. So i figured lets give it a shot. Yesterday my tank had it's first shot of Sky(it was on hand). I am going to chronicle all this at http://applesreef.blogspot.com/ if you want to follow. I will use this thread to post when I update the blog.
