Artificial Man made rock that mimics and looks even better than some live rock harvested from the ocean . this product is really good looking and have great shapes that are easy to scape with . This product is in our opion the best artificial live rock on the market we have used this personally in our own tanks and customers and never get any complaints. The biggest thing for me is that its not pourus like live rock harvested from the ocean , and besides not having any pests , it does not store phosphates or nitrates .
