Ok, ive been scouring the internet looking for some base rock for the saltwater aquarium that I will be setting up, and i've been coming across many places like marcos rocks and bulk reef supply, but in the end I would still end up paying like 150.00 for 40 pounds. So I start thinking, and I say to myself, why not try a quarry in town? I live in Corpus Christi Texas, so I called a Landscape Supply Company/ Quarry in San Antonio Texas, and asked if they sell Lace Rock. Sure enough they do, not only do they sell Lace Rock, but they also supply Lace Rock as Dry Base Rock to LFS in the whole area who turn around and sell it for 2-3 dollars a pound! But the best part of this whole thing is when i asked the price........ 50 CENTS A POUND! YOU HEARD ME CORRECTLY 50 CENTS A POUND. I will be buying about 60 pounds worth of rock next time I visit home and paying a scant 30 dollars. So if you live near San Antonio, Texas and need Dry Base Rock, make the short drive to Keller Building Materials. They even have a website!
