I added a plant led over the second chamber in my 12g biocube today, and moved innsome chato. When the display lights turned off I noticed a lot of light leaking/spilling into the supposed to be dark display. I turned it off for tonight, but I'm considering options to solve this. A light shield I can put unto the led and stop reflection into tge display would be perfect. I was thinking acrylic.....but where do you buy sheets of non transparent acrylic?
