I am about ready for fish (finally). First I need a canopy for my 75g. It had to do several things in this order.
1) keep my wife's cat from drowning himself (MOST IMPORTANT!)
2) look nice - be something more than a 2x4 box framed with plywood
3) be functional - keep fish in, well ventilated, hold my lights
Here's what I came up with. Sorry the pics are grainy, I used my phone camera.
First, I made a rectangle minus 1 side with 1x4 that measure the exact measurements of the top of my tank.
Then I cut 1x6 to go around the 1x4 and used 1x2 to make the back cross brace. The cross brace in the back leaves enough of a gap for all my hoses and cords to run out the back. The 1x6 is resting on the ground, the 1x4 is half an inch fromt he floor, the result is a 1/2 inch lip that goes around the top of the tank. The lip will prevent it sliding off when the cat jumps on top. I painted it black to match my stand and furniture.
I used half inch lip because that made the gap at the top exactly the height of a 1x2 which yielded the final product. I made two slotted platforms out of 1x2. Both sections just lift in and out. You can't really see the lip well in any of the shots.
I used an AH supply 2x55w kit, you can see how it fits in here. I put the ballast in the back. I designed the hood like an arbor of sort so it would ventilate well. In this pic you can see how the two platforms lift in and out. They aren't held in place by hinges or anything (KISS).
Here is the finished setup on top of the tank.
Lemme know if anything is unclear. I'm still undecided on if I want to use glass over everything, just the back, or not at all. I'm leaning more towards not at all or just the back. Any thoughts?
