wtf is that thing at the very bottom of the photo?
looks like a tan/orange monster sized spider leg(s)??
btw first photo on first page: awesome-ness, just about every true hobbyist feeling coming home with a new tank and a new project in mind ^^
I was going to de-rim my 20long but i had a nightmare the night i bought it about it collapsing and the glass getting permanently wedged together (at an unusable angle) as a de-rimmed tank.. soo just gutted the silicone and redid it (was globed in their real cheap like, now loks clean and minimal atleast).
