Cover or no cover?

[kenter16]

I am trying to decide if i should leave my glass covers on my tank. They always have evaporation water on them and i think it is effecting my lighting. The only fish i have right now are clowns. I am guessing that i would have to top off my tank more often. Any advice would be very helpful.
Also i am running a 2x96 watt CFL light. My tank demensions are 36x18x24. Is this enought light for a Bubble coral and a Hammer coral?
