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?

I personally would not do a planted tank with an overflow and especially an UG filter. The trickle filter will gas out a huge amount of CO2 and the UG will limit root growth, and be a trap for bacteria.

No trickle filter in this set up, the co2 diffuser would be near the return pump anyway. and since the ug filter is in the sump with just moss and maybe water sprite not to worried about roots. I've also heard that that is a myth about ugs and planted aquariums. Also isn't the whole point of a ug to trap bacteria? :) I know ugs get a bad rap but i have never been anything but successful with them.

It says in the very article you posted that you would need 6-12 inches of gravel to create anaerobic conditions, not to mention you don't really need anaerobic bacteria in there because the plants will take care of most of the nitrates anyway. Also anaerobic bacteria isn't really bad it is useful in removing nitrates. Also reverse flow ug's work pretty good and don't clog as easy as the traditional methods. Since the ug would be in the sump I am not going to be disturbing the main tank if I do a gravel cleaning anyway. I know a lot of people are saying not to but I am going to try it anyway. I let you all know how it goes. You never know until you try and this is something I can do with the equipment I already have. Thanks shortsboy that was an epic thread but had a lot of good info.
