I have like 50 million sq.ft. of the bird netting left over. I could give you some if you want. I'm probably not far from you. I really don't see why you would need to order the clear stuff from BRS, as the black version I have doesn't appear to block any significant amount of light. Here's some pics I just snapped. Probably could see better if it wasn't after "lights out". I used some eggcrate on the rear to avoid having to make an irregular shaped screen top, which I'm fine with, because I have swimming space behind my rocks, so no corals at the rearmost portion of my tank.
