This is the sump I use and it works great,

bought it at Lowe's, damaged box so I paid $80.00, and use it to pump from my basement up a flight of stairs, about 40 feet of hose, into the DT. It does not come out forcefully but it's a good steady stream. I just attach it with a rubber band to the to part of the overflow and I stay close, just in case it falls off the tank, and let it fill up. Also as a cut off I use an extension cord and plug it in beside the aquarium so when it's full I just unplug it. Just remember to get the hose out of the tank when you turn it off or it will siphon back to your storage container. Good luck, Oh yea everything is encased in plastic and the impeller in also plastic so it's totally reef safe.
