Caribsea LifeRock shelf rock is engineered from ancient Pleistocene seafloor, composed of 97% pure aragonite calcium carbonate with beneficial trace minerals including strontium and magnesium. Its distinctive 50% void space creates an ideal habitat for billions of beneficial bacteria essential for water purification. Pre-colonized with AragAlive™ bacteria technology, this rock dramatically reduces traditional cycling times and eliminates the need for curing. Multiple aragonite coatings preserve macro and micro-porosity while delivering the authentic aesthetic of an established reef system from day one. Sourced without hitchhikers, organics, or unwanted algae, LifeRock delivers immediate biological and visual results. Sold per kilogram.
