You will get all kinds of arguements about lighting blockage etc, but pound for pound, I'll choose eggcrate
It's so easy to work with, no frames needed, can be trimmed as required, cheap to replace, etc etc, ....

+1 for that. But is there really 1/4" egg crate?

this, I agree with, which is why I still use it with my 5g despite the grid shadow. (which you won't see on a tank with T5s)

What you could do is put egg crate on top of your tank as the rigid frame, then place something else on top of the egg crate to stop jumpers in their path. Of course, that's more money in it and will probably block even more light.

1/4" is the common stuff you find @ places such as Rona or Home Depot
It's lighting diffusing material, sold in the ceiling tile area, not near the lights in my local store, but close to the bulk wood stuffs

Go buy a $14 piece Boss and try it out :wink: :mrgreen:

Thanks Greg :D I will look into it.

Ok now its getting intense! :lol:

:lol:

Egg crate never stopped my sharks from getting through :S

The most common is 1/2" not 1/4". I think what makes the egg crate still work at 1/2" is it has some depth to it, so unless a fish is jumping perfectly straight up through a particular square it usually gets hindered enough that it doesn't make it through.

That screen in the pics I posted is almost a year old, and I've never cleaned it. No salt creep here.
If you go egg crate, have someone put it on and off while you stand back and see if you're ok with the amount of light blockage. I don't know if it's because of the height of my fixture, or if it's the LED's, or what, but it's a significant drop in light on my tank.

Ah my head is hurting :sad:
