I currently have a co2 scrubber utilized. But really wanting to do a airline outside. I know I need to go big on this since there's a distance. My problem is drilling a inch hole in the siding. Looking for ideas that might work. I thought a small tube like a 1/4in diameter tube to the out side but on the inside running to a larger tube the that large tube through the ceiling of the basement and then right into the air intake of the skimmer. I might be able to go a little bigger that a 1/4in tube but not much more. Thou g.j has please.
