so i am wanting to build a sump for my aquarium. I am wondering though if there is a way to equalize the output flow with the flow going into the sump o matter what setting i have the pump at if u get me? As in as water is pushed into the tank by the pump an equal amount falls down into the sump, no matter what the flow rate of the pump is set at? If this makes sense any help or advise would be appreciated.
