Overflow in planted tank

Hello I am new to the site but not to keeping planted aquariums. I recently moved and this gave me motivation to set up a new tank. All my old tanks have used canister filters but I am thinking of using a overflow that will run into a fw refugium that will include a reverse flow ug filter. I really like this idea as to hide the co2 system, heaters, and filters, put am a little concerned about its application in a planted tank. Will all this circulation and generating the co2 in the refugium effect the co2 levels in the main tank. Also I would like to do a moss wall but am a little worried about the moss getting sucked into the overflow and clogging it. Any thoughts?

Really the UG is more you don't need it and becomes just another maintenance item. overflows and sumps in planted tanks seem to be getting more popular, I love mine. to cut down on CO2 loss eliminate as much surface agitation as possible and cover the Sump. if you can make a full siphon setup for the overflow this will help immensely with CO2 loss.

a full siphon setup and covered sump makes more sense to me (having a sump) in a planted tank situation... wouldn't this be counterproductive? i thought the whole point of having an overflow sump was to oxygenate the water?
