7 gal bow

WoW !!! Whuts the specs on that?? I'd love to set up a killer 7 bow gal...wondering on your filtration?

4gal fuge, 32watt 50/50 and a 13watt 04, 12lbs tonga branch. I run a 404 to pump water into the fuge and another 404 for circulation in the tank. I also run a cheap air driven filter in the fuge with carbon. Two gallon water change every week.
