I'm going to build myself a scrubber, but I'm wondering why every feels the need to run water over the algae? Why not simply have your screen in a narrow "wall" of acrylic and have your water be bumped through this containment area, filled to the top of the screen. Water will still be circulated through this system and thus having nutrient exchange. Is a system where the water pours over and runs down the screen/algae better for some reason?
