Cornerstone Reef Rock is the new standard of premium live rock alternatives. Build the seasoned look of a reef instantly with a rock that is not only friendly to the environment, but has the looks to match. Each piece of rock hosts an intricate web of micro pores that provide unparalleled micro-porosity enabling maximum colonization of nitrifying bacteria, enhancing system stability. This is done by blending inert materials into the rock in such a way that creates a product that is strong, yet light.
Cornerstone Reef Rock has approximately twice the volume-to-weight ratio of comparable live rock alternatives. This allows aquarists to not only achieve the exact look they desire in their tanks, but also gives them far more bang for their buck.
Branching and premium are the two styles of rock we currently carry. Cornerstone Branch Rock has the natural look of mature Tonga live rock. Cornerstone Premium Rock comes in a variety of shapes and styles and is more reminiscent of standard live rock, with both rounded and shelving pieces.
With a rigorous leaching regimen, and with added spored bacteria, Cornerstone Reef Rock not only does not leach nutrients into your system, it helps to jump start a new tank and add stability.
With many unique shapes and counting, Cornerstone Reef Rock provides all of the variety to create nuanced reefs, from stacking, arching, open concept and more.
Please Note: Because of the fragile nature of this rock, it is possible for the rock to break during transport. We do our best to package the rock sufficiently to minimize damages. Rock is not insurable and we are unable to replace or refund damaged pieces. If desired, multiple pieces of rock can be reattached using aquarium glue or epoxy.
