Foundation rock is the perfect all-natural choice for the bottom section of an aqua-scape. Place it right against the glass bottom before adding sand for an ultra solid build. Machined from MarcoRocks ReefSaver rock- MR Foundation is the perfect choice for any aqua-scape design. All MR rocks are harvested on land from an extinct reef system buried when the Florida land mass was formed.
MarcoRocks is the choice of many public aquariums, aquaculture facilities and custom tank builders.
