Got a lifereef skimmer. Not sure what size tubing is used on it. But got a distance of 7 ft up the wall the 3.5 feet to the outside wall. What size tubing should I use. Then my second question here. I heard people say wrap carbon in filter floss. Has anyone used a media reactor with carbon and filter floss in a media reactor. Or carbon in the media reactor and still in the airline use filter floss to keep bugs out.
