I think you missed his point on finding actual real LR from the ocean selling for $2-$3 a lb here... base rock is what you will have. Have you considered the time it will take to properly cure homemade LR, as well as being able to make enough to keep up with any demand?? How about the liability aspect if for some reason your LR nukes somebody's tank?? Before putting the cart before the horse you should first see if you would even qualify to become a sponsor, and do what you are proposing.
Cheers,
