it looks like it may have trouble bringing the water up to the filter because of the distance
sometimes it helps to a) make sure that there is no air leak where the intake tube connects with the piece that extends down, and b) to prime the filter by making sure the filter chambers are completely full, so that water gets pumped out from the start
if for some reason there is no movement, but the motor is clearly on, you may need to clean the impeller
it's still quite a distance though
you might be better off with a submersible filter
