Your one stop shop for the best in Holey Rock. 

General Ordering Guidelines

First, multiply the capacity of your aquarium in gallons by 1.5. This number is the number of pounds that is a good place to start. Mix and match quantities below to get the right mix of sizes. Rock Sizes: Small 1-6 lbs. Medium 6-15 lbs. Large 15-30 lbs. If ordering an Upper Crust rock, we highly recommend ordering 20lbs of stacking rock with it for bracing and balancing. Shipping is included in the price of all rocks to the lower 48 United States. We ship to Alaska, Hawaii, and internationally with additional shipping charges being applied after checkout. All orders ship UPS Ground unless otherwise indicated. Contact us for expedited shipping.
