Not a genius in fluid dynamics, so bear with me.
Simply: How do I determine equilibrium for my pump and overflow.
Have a 75G reef-ready with overflow. Sump is a 20G tank with a Mag 9.5 (950GPH) pump. Placed a flow valve between pump and return to govern the return.
My guess is that I restrict the flow from pump to tank, so that the overflow is just a bit quicker than the return... then once water drops below the overflow mark, it stops flowing to the tank, then the pump catches up.
Is this right?
Just trying to avoid disaster and divorce papers being filed for ruined floor and carpet...
As usual, thanks for the help.
