On the slot pipe, make sure that the water creep blockers, which are the sections of airline hose with a zip-tie through them, are rotated such that the airline hose is centered on the bottom edge of the pipe. This only applies to the first batch or so of Rev 2 scrubbers I sent out. I have more recently been using 3" of hose instead of 1". Feel free to cut the old airline hose water blockers off, and install longer sections of hose.
