To cover or not to cover

So I got a cover to cut down on evaporation but I'm reading that It might not be a good idea.

Well, the cover arrives tomorrow and I'm wondering if I should refuse the shipment.

I'm getting something or the same as the one Smitty has or had. ( I searched the forum)

Any thoughts would be much appreciated!
 
A solid cover will hold in heat and interfere with the gas exchange. If you dont have a heat issue in the summer and you are running a uncovered sump with a skimmer it wont be a problem except for the salt creep you will get on it.
 
Yeah, having glass lids can suffocate the tank and raise the temp of the water, unless you have an open sump/fuge. Especially being in California where it's always warm. Try building a mesh top instead.
