First, beautiful yes.. but full of good and bad critters.. I mean full!
Second, the Walt Smith 2.0 rock is placed in the ocean to cure as well, so TBS is not the only one doing this. I am running the 2.1 rock and absolutely love it. I seeded it from my main tank and now I have clean live rock.
Reef Rock 2.0 & 2.1 are the new rocks by Walt Smith. Most of you know Walt Smith as the major supplier of live rock to the aquarium industry. Reef Rock 2.0 and 2.1 are the update to their previous man made and aqua-cultured rocks. Reef Rock 2.0 is their aqua-cultured version that is placed in the ocean for six months before being sold. Reef Rock 2.1 is the dry version of the same rock.
The rock is available in a variety of different shapes and styles including honeycomb, shelf, and cave rock. The rock is made with porous materials mixed in to make it extra porous and light. Because of the porosity, Reef Rock can be up to 30% lighter than its live rock counter part and make for a great host for beneficial bacteria.
As the acceptable quotas for live rock harvest decline in the upcoming years, Reef Rock has the potential to be an acceptable and sustainable substitute.
