Event Horizon, Forgot about this modification for increasing the flow of multiple waterfarms... After adding a GH recirculating kit, you change the controller by adding a 1.25" standing water column in place of the pumping column that comes with the kit.... Then you drop 3 pumping columns into the standing 1.25" column of water... Now it will move three times as much water as a regular GH recirculating kit would move...
