Yes on the out flow side. But I would not what to use it. Even restricted it will move to much water and you would be using a lot of electricity and wearing out bearings for no reason. I would say a minimum of 4 200gal tanks with valves, a 2in manifold and 1.5in running to the tanks. A lot of fish stores use that size pump to circulate the water in all there freshwater tanks. So it can be done just depends on how you set all your tanks up with it. Hope this helps????
