Many people are using Black blasting sand as an inexpensive substrate. Well I purchased too much for the 40g lol I have (1)50lb. bag left that I do not need. To give you a good idea of how much it actually is, I used only one of the three bags in my 40b, and gave a second to my brother. It is the 20/40 grit. and looks great!
I am not looking to make any money off of it, but break even. So 5.00 plus pickup gets the stuff.
Local only, there is no way I would ever suggest shipping this stuff lol
