Energy said:I used fiberglass resin to coat the styrofoam. The stuff in the previous link is for mounting frags. Different stuff altogether. This winter I might try to post construction pictures for everyone. I photo documented the entire construction process to share when I had free time. I might be able to get some photos of the fish room at that time as well.
SWEET!! That would be fantastic if you find the time Energy. By the way I remember reading that you contemplated making your own rock. why did you choose the pvc racks over the diy rock option? I am in the process of making that decision myself and any insights would be great
