Ok ya'all. Got a question. I just got a 110 gal tank with an acrylic canopy. It has 4 fans two that pull air in two that push air out. There's only 3 inches of clearance between the top of the canopy and the aquarium itself ( it's an acrylic tank). Any ideas how to mount lights? I can't put any type of screws in this hood. Is the 3" clearance too close?
