So many carpet surfing stories .... we need a thread on "covering your tank"

[gregzz4]

Why aren't more of us covering our tanks properly when we know full well that our critters are going to attempt to go for the moon sometime ?

I currently have eggcrate over my DT, but am going to build a mesh cover of some kind before I introduce my first fishies.
Besides the fact that it blocks light, I have seen some evidence ( thanks Kenny ) of corals becoming 'sun-tanned' with eggcrate
Why aren't more of us using something to properly protect our charges ?

So;

What are you using to cover your tank ?

What would you rather use to cover your tank ?
