Hey guys i just wanted share my 12gallon nano with all of you. Its been up an running for 1 year now in my office out on an oil rig. everything is stock on it. no skimmer no koralia pump. 2 CF lights on a timer. I do 2gallons water change 3times a week on the weeks i'm working. I get ocean water from 200 feet down off a sea water lift strainer valve. We are 8miles off the coast of california. This little tank is doing amazing! sorry for the terrible pix, all i have for a camera out here is my cell phone.
