CaribSea LifeRock Shelf – 21 in

CaribSea LifeRock Large Shelf – Approx. 21 inchesLifeRock begins as a sunlit piece of Pleistocene era seafloor thriving with living creatures. Over the next 100 millennia and the retreat of the ocean this ancient piece of seafloor now well inland has formed a pure aragonite-bearing rock. This clean base rock is 97% calcium carbonate with minor and trace elements such as strontium magnesium and barium. This base has an amazing 50% void space which will provide residence for billions of water-purifying bacteria. LifeRock is infused with bacteria using AragAlive technology which results in a reduction of traditional cycling times. Each piece of LifeRock has multiple engineered aragonite coatings that not only maintain the extensive macro-and micro- porosity but yield the soft muted colors of a living reef. LifeRock is a superior rock of true marine origin without hitchhikers organics or algae. No curing is required. With LifeRock you will get the look of an established reef from Day 1.
