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?
