Easily stackable to create one-of-a-kind aquascapes that feature pillars, shelves, overhangs and caves.

Very light due to its extremely natural porosity with plenty of surface area to grow beneficial nitrifying and denitrifying bacteria to act as biological filter to help maintain pristine water conditions in your aquarium.

Cheaper, better weight/volume ratio and more environmentally friendly than live rock. We recommend 1 to 2 lbs (0,45 to 0,90 kg) of rock per gallon (3,78 liters) of aquarium water. 1 pound (0,45 kg) per gallon (3,78 liters) for a open-water landscape with more space for your fish to swim. 2 pounds (0,90 kg) per gallon (3,78 liters) for a denser landscape so you can create more caves/crevices and more area to place your corals. Please note the pictures displayed on our website are merely representative of the rock you will receive so the actual size, shape and appearance will vary with each order. To seed your aquarium with beneficial bacteria, just place a separate piece of quality live rock in your tank along with The Reef Rock or use a bacterial supplement to kickstart the cycling process. Soon your dry rock will be alive and beautiful!
