This highly porous rocks aid in biological filtration, water circulation and provide hiding places for fish and invertebrate and are easily stackable to create one-of-a-kind aquascapes that feature pillars, shelves, overhangs and caves.
The nooks and crannies in each rock make it easy to mount your favorite coral frags and is guaranteed not to introduce undesirable hitchhikers, like algae and aiptasia or any unwanted organism.
This rocks are as good as natural LIVE ROCKS and to make it work like LR, we just need to seed it with natural LR.
To seed these rocks with beneficial bacteria and other living creatures, algae, just place a separate piece of quality live rock in your tank along with these or use a bacterial supplement to kick-start the cycling process. Soon your rock will be alive containing coralline and macro algae on the surface if seeded with a few quality Live Rock or Coralline Algae.
