I forgot to mention mine go horizontal for almost as long as they go vertical. Horizontal is under the main tank, before entering the sump. Also I found with my Stockman, if I had too much air, it would cause burping problems, you really need to get just the correct amount of air, then the entire line should be full of water, and should be silent. This is how the Stockman works. Durso works slightly different, since it requires a restriction in the line.
