I have just set up a Rio 180 and was placing me co2 diffuser. I initially placed it on the right hand pane below the filter inlet, I decided this might reduce carbonated water as it would flow straight in to the filter knocking the carbon out. I then decided to place it under the filter out let as this would push carbonated water around the tank. However to get some good surface movement I have a small air wall in the middle at the back of the tank and the water flows straight into it. I don't really want to move it the other end of the tank as it is more of a desert environment and the filter end is more a jungle environment hiding all the parafinalia. Anyone got a ideas?
