Lights say covered tank only

[gla3dr]

Hey,

I just bought some lights for my reef tank (the kind with legs that rest on the edge of the tank) and they say to use them only on a covered tank. However, I do not want to cover the tank because that hinders gas exchange at the surface and I've read that having a cover is a huge pain. I do have a sump though, so would the gas exchange down there be enough if the tank is covered?

Thanks for any help.

you would still have a problem with proper light penetration and overheating tank. Either way, they usually put those warnings on there due to splashing from water, but its not a real concern.

Alright, no cover it is then. Thanks for the quick response.
