Was wondering if anyone with a 29g biocube could help me out here... i know the general rule of thumb is 1-2 lbs of substrate per gallon, but I realize that this is obviously going to be different depending on the shape of the tank, as well as the density of the substrate...
So my question...
So I've spent about 3 hours searching and searching the net for answers to this problem... and found this:

I purchased this for 20 dollars... it's a buffing pad that attaches to your drill, and some of that cerium oxide powder...
