The glass was spotless but I didn't have any masking tape, I'm gonna resilicone it and mask it off because I'm really not happy with the silicone job. It doesnt leak tho. I'm still debating wether or not to drill it on the back or bottom. If I bottom drill it for 3x 3/4" bulkheads I'll lose 2 inches of depth for an overflow but it will look real clean from the outside or I can drill the back, not loose any depth but I'll have hoses sticking out the back unless I build the stand to cover the back.
Here's my old refugium, its drilled through th back same dimensions just shorter
