MarcoRock Foundation Rock

MarcoRocks Foundation Reef Saver Rock is the perfect base to any desirable aquascape. Each piece of foundation rock is cut flat on one side for stable placement and an architecturally sound aquascape. The natural rock top-side lets you place traditional rocks on top of the foundation pieces without creating excess pressure points or strain on the base of the tank. If you are going to with a bare bottom tank the look the foundation rock gives is awesome and even if you are going to be using a sand bed, placing a few pieces of Foundation Rock approximately 6″ – 8″ apart will allow for proper flow throughout the base of the structure and allow detritus to be swept away.
