There is no claim being made that this is more efficient, the only reason why its long is because the reactor is being ran horizontal instead of vertical. Plus i had to buy the 4" pvc at a minimal length, so i cut one foot off it and built it to fit behind the stand. We enjoy the equipment aspect of the hobby just as much as the stuff inside the tank
