I melt my cube in a cup of tank water for about 30 min. When ready to stir in the cube I make sure it is melted in the water and add in front of a powerhead.
fishfanatic, I wouldn't start out with more than a half cube. That would have to be cut in half if you use the normal size cubes. I'm using a whole cube in my 120g.
