I have to move some aquarium stuff out of storage, including some big tanks and a couple of trash cans of XXL Tonga Premium branch rock. Real rock, not synthetic. What is the current price of this stuff? Last I saw it was like $12-15/lb. As far as I know this quality of Tonga Branch hasn't been imported in almost 10 years. What's the best way to sell something like this? Take photos and price each piece individually? Sell as a lot?
