Aquarium cover?!

Can I put a glass cover over the aquarium? Some opinions say it messes with the light spectrum, some say it doesn't matter... What's the deal?

I mean, it seems like it would be an advantage to have a cover instead of open... No jumpers, less evaporating, keeps dust debris out more... How come there are so many open top aquariums? Is there a benefit for leaving a cover off?

Yes the gas Exchange is the main reason for an open top it effects the PH

Ohhh... That makes sense, now we're getting somewhere! So, surface agitation also helps the gas exchange, no? So if I increase agitation, and put a top on, would they essentially cancel each other out to a normal level of gas exchange?

The tank is 13" deep, and has a center brace across the top in the middle. I was going to have 2 pieces of glass cut because it is technically 2 sections. Was going to leave about 3" open in the back to allow room for filter, skimmer, cords, etc... So all in all about 75% of the top will be covered

That should be a problem then if there's surface agitation but if there is a small fan will solve that problem just blowing into the opening

Ok so you DON'T want evaporative gases re-entering the system? Did I interpret that correctly?

It's more that u want oxygen to get to the surface Then evaporation to escape but takes one for the other I guess lol
