CaribSea LifeRock Arches Only(4 pk) - 20 lb box
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.

Nice rock Nov 3, 2022
Very colorful and adds a good color to the tank along with the stacking part. I stacked mine without needing anything to hold it in place but it does holes where you can used during stacking.
