Ok strolling around the the GARF website. I saw they offer a product called Aragocrete which is basically concrete with a base of aragonite sand. Im wondering how long it would take for this 'Rock' to become live? As it is very unsightly at first.

Also apparently it is lighter than say Fiji or Tonga rock could this lead to stability issues with flow?

Has anyone purchased or made their own Aragocrete? If so what was the outcome in your tank how long until it was seeded with the coralline? How do your fish and corals react?
