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.
These natural porous calcium carbonate rocks are sliced on two sides to create ledges, platforms, and caves, and are perfect for fragging corals of all sizes. Flatz can also be used to design interesting substructures, rock footers, and sandless substrate beds by tiling in across the tank bottom. Each box contains a variety of sizes from about 2 inches to upwards of 10 inches. LifeRock™ Flatz have coralline algae coloration.
