don't judge the rock "formation", that's basically where all the rocks ended up after i took it all out to catch the melanurus wrasse, and then put all the rocks back in so they don't dry out.
BYOB (bring your own bucket) - all mine have been re-purposed by the woman for gardening.
free sand and rocks if you take it ALL, a little money or couple frags if you just want the rocks.
garden variety aragonite sugar sand, it'll blow around until poop weighs it down. easily enough to cover 2-3" of a standard 120g.
about 90~100lbs of liverock. maybe 40 bucks or a few frags of zoas? just want to get rid of it so i can break down the tank.
rocks have got to go before i can dig out the sand if you just want the sand.
