Here is what it means:
Real Reef Rock is our standard reef building rock.
Because we don't carry real live rocks
It comes in a variety of sizes from small to show size custom.
Because cement is easy to work with
It is very light, porous and full of holes and crevices.
We added rock salt in the cement mix to form those
It is three dimensional in shape and comes in many natural shades of purple, pink and red.
Because we can get those spay paints for cheap in our local friendly hard ware store
It replicates the look, feel and function of coralline encrusted coral skeleton rock.
From our prospective, they look cool
It’s made from all natural reef eco friendly materials
Portland cement has the similar chemical composition to live rock after it is cured, aka Calcium Carbonate, it has been that way every since it was invented about a hundred years ago
and grown in greenhouses to become a bio-active rock, without the nuisance pests and hitch hikers commonly found on wild rock.
We socked them in saltwater
This rock is great for Marine Reef and Fish only aquariums.
Despite they look quite funny in color
Not suggested for Freshwater, as it holds a high stable pH.
Not really, we just don't want to kill your priced frontosa or discus because it will leach calcium hydroxide for a while
