It worked great my substrate was clean an if I raised the jets a lil more it would have stopped the sand blowing around but I pitched the idea after a few weeks at night when my fish were sleeping they would get tossed around by the jets so I added more big rocks and that just made more big holes in the sand if I spent the time to redesign the whole thing with taller jets and adjust the flow it'd be better but I was lazy and went back to a spray bar
