am i suppose to fill it up with groton or wat let me know and guide me in the right direction
fill the top one with groton up to the tall drain pipe and the bottom one with phed/nutrient mixed water. put the air stone in the bottom res and the pump in the bottom res and turn it on.. the pump should be connected to the short pipe/drain, it should fill up to a certain point and drain back through the tall pipe/drain.. when the pump turns off it drains back through the pump. it seems like it would be very hard for it to overflow because its so high on the edges.
