I had to install a cover on my tank to keep fish from jumping. I used a glass top for several months, but didn't like the glass because it accumulates condensation and salt spray which blocks light.
This project has been in the works for quite awhile now, but I finally got around to getting it completed with a significant amount of help from beakerbob. Bob came up with the idea to put the mesh material in a standard window screen frame.
I found this clear mesh material after a lot of searching on the net. It ended up costing a small fortune due to the surcharge of ordering such a small quantity and shipping. (If someone is interested in some, I did buy quite a bit extra.) The I used mesh with 1/2-inch openings, but I also bought some mesh with 1/4-inch openings. I think the 1/2-inch is small enough to keep my fish from jumping out.
The other nice thing about this screen is that it doesn't hold heat at all. After the halide was on all day, it was barely warm to the touch right under the bulb. And the best part is, it blocks virtually no light!
