Hey I'm going to have some extra live rock when I'm done stacking my 55. Probably will be about 25-30lb. It's not the best stuff in the world, it will be semi-cured. It used to be some really nice gulf stuff but Premier Pets let it go down the hole. So I picked it up for cheap. Basically I'm going through and pulling the dead clams and oysters etc. The rock is fairly clean algae wise. I'm just putting the word out early for anyone who is interested. The pieces vary in size for 1/2lb to 5. I have one bigger piece that I don't plan on using either.
