Sorry I dont have pictures right now.
He donated 50lbs for our school project and they looked great. A club member also bought 50 lbs for her 55 gal tank and she loved them.
I have some samples from the previous MACNA's.
I just purchased some sand from him. Got 120 lbs of pure white sand for $76 shipped and I had it in 2 days.
I should have a few pictures of the rock in a few days. I have a friend on travel in Florida right now and he sent me a text last night standing next to 1200lbs of the rock. He is bring back 400 lbs.
It is very very porous and very very light. They mine the rock from mines, take it and place it in 10 ton bins in the ocean for 2 years. Then they either sell it dry or live.
