i have my filtrations container above the water line, do i need an air tight seal for the pump to be able to keep enough water pumping to the waterfall? all of the water is draining back into the pond, not enough stays in the container for the pump to use. how can i fix this? or do i have to put the filter container below water line t0 work?
