Evaporation is your friend, because it allows your tank to cool cheaply. Topping off with fresh water is simple, and if you need help you can set up an auto-top off system to keep up with that.
If you are worried about jumpers, put eggcrate (lighting diffusers) on top of the tank. The grid will help keep the livestock in the tank but avoid blocking the light nor trapping heat.

I'm setting up my first nano-reef. I'm reading some debates on lighting, especially whether or not to use a glass hood. A common concern I've heard is that glass will limit the transmittance of certain wavelengths of light to the detriment of coral growth.
I scuba dive, and I've regularly seen photosynthetic corals in 70 feet of water. mind you, the water is very very clear in these dive sites, but does 1/4" of glass really change the light spectrum more than 70 feet of water?
I mean this as a serious query, because I honestly don't know. I lean towards a glass hood to limit evaporation (although if temperature reg. is a problem, off it goes) but I'd like to hear why a glass hood is bad.
