I used to use those dual pumps made for fish tanks to run secondary air lines around the perimeter of my buckets, but IMO you'd be better off going with a more heavy duty hydroponics designed pump vs. one made for a fish tank. As the guy at my hydro store said when we were discussing air pumps, "In DWC, you're better off getting an air pump that would blow fish out of the water if you ran it in a fish tank." :jointsmile:
What he said. and if your really worried about it get 2 dual air pumps and one line from each pump. Never seen 2 pumps go at the same time.
