I have some that i am selling. when i set my tank up about a year ago i had extra. Bought tank used and didnt use all the rock. I put it in a rubbermaid container,big one like you go camping with and set it outside behind my shed. I would say its dead-live rock. Deff dry!!! Going through a whole winter outside i am sure killed anything that might have have been living on or in it. And it got very little light,whatever uv's that passed through the container. I have just under 40lbs. Just weighed it. 1 ten pound piece,3-8lb pieces and then a few pound peices. No special shapes or nothing. Did a little looking around and it looks like $1.50 a pound is round about the going rate. So $55 for it if you want it. Let me know if thats too much, Im going to start a forum to sell this if you dont want it. Figuired id give you first dibs.
