Apparently my brain is unable to fathom the sheer volume of rock that is 250 lbs. My tank and sump are now over filled and I need to get rid of some. There is one piece that is probably about 20 lbs by itself that will go and lots of other large pieces. It just came in today, lots of dead critters and stuff so it will need to be cured before you throw it in your display tank but it is some very good looking rock. I'd like to get $3/lb and if you like we can separate it and leave it in my tank to cure before you take it home.
