Tops for use with Coralife Aqualight 96W or CSL PC+Moonlight?

[lunchingfriar]

I'm thinking about setting up a 10-gallon nano-reef with either the 20" 96W Coralife or the 20" 2X40W CSF w/Moonlight. The tank will be the standard 20" long 10-gallon size. My question is, what kind of aquarium tops, if any, would work well with either of these lights? Or do people even bother to use tops with them?

 

Thanks!
