Aquarium pump/physics/water head height
i have a pump (canister filter) that sits under my tank. it is quite happy pulling water down from the tank, through it and back up to the tank.
i am now going to send the water back via a cooler which will add some extra work to the pump so i want to make its job easier.
now the pipes to the pump have to go through a hole in the wall at 2ft high so outlet goes down from 5ft (tank) to 2ft and through the hole - i i mount the pump/chiller at 5ft on the otherside of the wall does this help the flow?
in otherwords the tank/pump/chiller are all level - but the water has to go down then up to them...then back down and up - do these ups and downs cancel each other out or make it worse/better?

They cancel each other out. If there was no pumping going on at all, the water level would be the same at both points.
Long lengths of piping cause exta friction though.
