So, basically there are mixed feelings about the Glass tops? I don't have any fish that jump, but I'd still like to cut down on water evaporation. I was dumping 1/3 gallon of fresh RO water everyday without the top, and have noticed that this evaporation has been cut down drastically with the glass top on. Does egg crate help with evaporation?

I'm not worried about gas exchange because I have a HOB filter and a skimmer.

Also, the light fixture I use comes with a thin plastic cover that slides out to protect the bulbs from water splash. Do you think that plastic also impedes the light as well.

PS. I'll get some pics soon.
