I'm setting up a new tank and someone locally is selling some TBS rock from a tank that has been running for 3 years. Looking at your site, it seems your big selling point is the variety of life on the rocks and how it helps "jump start" a system. Can anyone comment on the rock itself? If you were to choose between 3 year old TBS and 3 year old Kaelini, what would you chose?
