SUMP Problems

[figdish]

ok, so i got the sump to run smoothly but i think there should be more flow in the sump. the water doesn't have alot of movement other than over the wall into the skimmer area. Should i have pumps running in the sump, water surface just doesn't look right to me almost like there is a film on the surface? just don't want levels to go out of wack as everything pretty good right now? any input greatly appreciated, thanks all
