Mesh Lid idea
 

Someone pointed me towards this on RC

Mesh Lids

I did one very similiar. Although i used pvc instead of anything metal.
Works very we'll and haven't had any of my fish jump yet and i have a large amount of wrasse's.
Found the netting at homedepot after searching for something that was small enough but wasn't going to melt under the lights.

Works really we'll:)

Photos?

What type of netting did you use? Agreed, pics would also be nice.

I am at work. But when i get home i will take it off and post some photo's.
I will also have to look at home for the bag that the net came in. I believe it was used to keep birds out of your garden.

Neat idea. I like that better than eggcrate that's for sure!

The netting used in the link is called clear knotted bird netting.

I made a lid out of nylon mesh from Rona. It comes in different sizes, and is quite cheap. I made a frame out of wood and attached the mesh to it. Works great.

doesnt that affect the amount of lighting going to the tank just curious.

I wonder, which method egg crate or mesh has the most effect on the lighting?

Eggcrate easily. Its thicker and it directs the light only downward through the holes.

i was thinking to extend the height of my tank about 4 inches with eggcrate, that would hopefully stop mos fish jumping out, and not block any light?

has anyone tryed that before

You might have more success with the reflective eggcrate, but I'm not sure if it will heat up, or have a reaction to the salt water.
