Just obtained some nice pieces of Seiryu rock. The one piece I would like to use as a tall structure will not quite stand as its based is not perfectly level. I was wondering if I could fix a piece of rock to it to make its base more stable. Does anybody know if there a 'glue' (or alternative method) that is strong enough to do this and is safe to use within the aquarium?
Thanks,
Ian
