hey evryone i am in a pickle and need help..........
the problem is that my main tank is in the dinning room witch is open to the living room (in a apartment), and i veiw movies and such were it need to be as dark as posible in the evening's around 8:00 !
i dont mind the light coming from the tank that much, it is the light comming out of the back of the canopy and reflecting on the white walls and celing that is to bright...............so i want to build another canopy with holes for ventalation but not allow light to penatrate......
any ideas or solutions welcome

any other sugestions for concieration......?
putting a blow hole with fan on the top but covering it with a peice of wood slightly larger than the whole and mounted on little legs so that the fan can still get air through the four sides an option ?

The area in the stand off must equal or exceed the area of the fan opening and all will be well ;)
So if the space between the fan and the light block is 1" and the fan is a 4" biquet. the fan = 16 sq" the area around would need to equal that. so 1" would work 1" x 4"+4"+4"+4" =16"

What about the plastic vents they put in the sides of houses? They are slotted and would block out alot of the light ya can get them in 2 or 4 inch I think at Lowes. Simply drill the correct hole and slide the vents in?
