Should what be enough? You want a slower flow through your refugium right? Not sure what you're looking to do. You could always slow down the flow by reducing the flow output from the pump, you just need to make sure that whatever flow you decide on can be handled by your box, but with that head, without any modifications, I would think the box is adequate, but I always add a valve to control the flow of my pump.
