i'm stumped

[reefwars]

a quick easy fix would be to try a different return pump if you have one lying around or could borrow for a day, im having similiar issues and im thinking its my pump.

im getting exactly as scubasteve described as well.

pump has always been quiet and to change the pump means draining the sump partially and a rebuild on my stand.maybe its one of those little mysteries or it could be a full moon.thinking about a double drain but it would still run into the same bulkhead as i have no room in my overflow for another bulkhead and i don't want to drill my tank again
