What do you have over your tank and why do you like it?

[mandyplo]

What kind of cover do you have on your tank?

I currently have a DIY Mesh top that was done terribly and needs to be replaced. Whats the best route for me to go, and what will let the most light through?

I have 2 kessil a350W LED lamps hanging 1 ft above my aquarium surface.

What kind of tops do you guys use with your light fixtures that let maximum light through and why do you like them?
