Brian, it "looks" like soaker hose but a lot stouter and certanly must have multitudes more holes in it!! Very industrial looking. Peachgrower, I am running 3 diffusers. Pond is only about 12 foot deep but 2 acres. It was cheaper to buy 3 and I needed to run each one 150 ft. I built my own screened covered box for mine to keep it running very cool. It also has the fan on it that came in the kit.
