I don't think so, at least not IMO. The purpose is not to stop and start the flow as it is to reverse the flow direction, or increase the flow dramatically. For the latter, it might work to have a secondary pump that is cycled on and off, but this would not account for the directional reversing.
What about a combination of the waterfall standard slot pipe and a spray bar like acorral uses on his scrubbers, except more randomized hole placement, then one could turn that spray bar pump on and off to break up the growth pattern? I'm thinking of something funny now, our kids have a sprinkler that they play in that has a bunch of rubber hose sections that flail back and forth...like this http://www.sears.com/sports-and-toys..._tnt=39869:4:0
