I made a diy canopy with a 96 watt power compact 50/50 lighting system. After plugging it in and running it for about an hour or so i noticed the top of the canopy wood was hot. It is nessesary to install a fan, i have a piece of arcrylic in between the water and the lighting system and im hoping that the water is not being heated up too much. is it nessesary for me to install a fan? here are some pics.
ps: the black and red thing on the left is just a lid for my filter
