    I would say slow enough for the detritus to settle, that the critters can "eat" the detritus...

    The "average suggested water flow speed" through one's sump (and this includes the live rock section), is 2 to 3 times your tank's DT water volume.

    ie. If your tank is 300 liters, then ie a 1200 to 1500 liter per hour return pump (to counter for the head loss).... your return pump's size determines your water flow through your sump.
