FS: 9"x48" 95% reflective aluminum sheet metal

Just lined the rest of my canopy with this stuff and it made a dramatic difference on the light output into my tank. Have this piece left over. $20. PM me if interested.

What about heat?

What about it? Didn't change the tank temp at all for me. I have leds supplemented with t5s though. T5s have individual reflectors too. There was just so much black in the canopy I figured it can't hurt to put some reflective material around. Really helped with brightness and shadows for me.
