Would a glass top on a tank cause high nitrates, by not letting gases to exchange? Just wondering.

in a way yes it would not allow for proper gas exchange. but i do not think that in itself would create a nitrate problem.
 
Do you have a sump? If you do I don't think the glass tops have much impact. There would be plenty of gas exchange happening in the overflows and sump.
 
Same goes if you have a skimmer on the tank, no need to worry about gas exchange.
NO3 buildup wouldn't occur from lack of gas exchange AFAIK if there was a problem directly related to keeping a glass top on the tank it would be a lack of O2/overabundance of CO2.
 
In my oppinion the main problem with having a glass top is heat. Having a glass top traps alot of heat in your tank. About 4 degrees in my case, and i only run normal output florucent lights. If you have a sump that wouldnt be as big an issue, but with out a sump i be willing to bet that you will have some heat issues. Also glass filters the light to some extent, and any saltcreep that forms on the glass would block light. I ditched my glass top for eggcrate. I have to top off more, but atleast my tank its running at 85-86 degrees anymore.
