Seeing as I only paid 15 bucks for the sheet, pretty sure its the cheap stuff. Another hardware store had it double the price, so betting they had the more expensive stuff. The strip along the front of the tank stops right where the light bank begins, it's only about 5-6 inches wide, so it's not blocking any light. Just keeping fish in and look a heck of a lot better than a strip of bridal veil netting that I used to use. The lid sits on the edges of the EC to keep it in place. Once cooler weather hits, I can go back to closing the lid. The display refugium just has colts and xenia and some macros. The lighting is adjustable so I suspect that tank is okay although when I plumb the two tanks together, I'll probably do the combo of netting and EC. The hex will only have fish so don't need lighting there. Very handy stuff! Lots of pcs left to make frag racks!
