Hello from NW Iowa!

Hello all! Saltwater newbie here in NW Iowa! I have been keeping discus and angels in my 150 gallon freshwater tanks for about 4 years now so thought I’d give salt a try! I have a 75gallon full of diatom at the moment. I have stocked it with:
5 Royal gramma
2 clown
A yellow watchman goby
A diamond goby
Som snails and hermit crabs
Sand sifting star

I read somewhere not to have glass covers, can anyone tell me why?

The exchange of gasses happens @ the water surface. Covering the aquarium inhibits that exchange. Not that it can't be done but it is frowned upon in the saltwater community.

Welcome to Reef Central.

Enjoy!

Welcome! As @Vinny Kreyling and @Uncle99 pointed out for gas exchange and a mesh top (or egg crate (a little less clean of a look and not practical for rimless tanks, I use egg crate) solve the issue. You’ll still have greater evaporation, but yea, that’s what an auto top off is for
