Additional Information

The best base rock you will find for your aquarium. Marco Rock dry base rock is the most porous, lightweight and has the greatest surface area of any rock we have seen.

This rock does not contribute to the destruction of marine habitats. It is a quarried rock, quarried on land from an extinct reef, a reef buried when the Florida land mass was formed so you're guaranteed a 100% pest free, clean start.

A great looking rock that stays put and "stacks" like a dream, making those long frustrating hours of aquascaping, re-aquascaping and chasing avalanches a thing of the past. Ask anyone that has worked with it, there's something unique about the structure and shapes that make each piece want to "interlock".

In an average 50 pound box you will expect to find 3-4 football sized pieces and an assortment of smaller sizes to fill and round out the box for weight. We don't pack rubble rock in these boxes, however we do add 1-2 lbs to make up for rubble that may occur during shipping.
