Caribsea Liferock Shapes 20Lb Box

These open, light shapes not only provide lots of cover and 'Play area' for fish, but provide nice nooks and shelf areas for inverts too.

Plus, because Life rock Shapes are so open and 3 dimensional, 20lbs goes a long way.

The beautiful layout you can make leaves lots of open water areas so flow rates are at their best as well.

Each box is different, and every rock is too. Please be aware the pieces in the image are for reference only.

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 colours 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.
