Awesome... Thanks.... John can you confirm that... It was a crab that was making the clicking .... snapping sound. I know that I have at least one crab left in there (Ihave bannished about 12 of them to the sump) that I can not get at. I will try to indentify it. I never really considered that it could be a crab.

Doug where the sound is coming from is the center to top area of my left tower... so no glass.
