Andy, that's cause I stoles it from ya!
It's from ORA, as are all the clams, captively raised. It has nice little blue centers in the spots.
Skylsdale,
here ya go, along with a bad pic of the overflow on the 1" bulkhead. It's just small pieces of black acrylic I glued together, then epoxied to the back wall. You can also see two little acro frags base plating at the bottom left of the pic. I haven't cleaned the glass in a couple weeks.
