Plumbing

I picked up a used RS-180 today with an Ehiem 1262 pump on it, and it appears that the pump might be bad. I only paid $100 for skimmer and pump so not too upset but hoping it can be fixed. It pumps but not strong enough water will not rise fully up the skimmer body. It only goes to the gate valve adjustment tube. It does not flow out the top of the gate valve with the neck removed and valve opened or closed. Any thoughts?

Picked up a used MP40W last week from another member and then last night got a new EcoSmart MP40 and I have been playing with them ever since. Because I only have 1 EcoSmart pump I can not use any of the EcoSmart programs with both pumps so I have it setup currently in long pulse mode at about 80-85% power and 10sec pulse. I also have it go into night mode at about 10pm when all of my lights turn off. So I was just wondering what program everyone else is using and why?
