LifeRock™ 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.
Please Note: Because of the fragile nature of this rock, it is possible for the rock to break during shipment. We do our best to package the rock sufficiently to minimize damages. As FedEx does not consider this item insurable, we are unable to replace or refund damaged pieces. It is possible to attach multiple pieces together using aquarium epoxy in order to make large shelves or repair damaged rock.
