You could use a small ProCon Rotary Vane pump but I wouldn't run it unattended at night. These pumps are extremely durable and easy to use but you can't run them dry. That's why most folks use the little Aquatech's...you can run them dry and it won't hurt them. I know there are many people on this forum that use the Aquatech's and let them run overnight. Maybe someone else will confirm.
