Water motion in tank.
Steve,
Low RPM motor ... how about one of those BBQ rotsiere motors. Or how about a stepper motor [img]images/smiles/icon_smile.gif[/img]
Another alternative for water circulation is using one of those plastic water sprinklers ... the one that was three heads and they turn round and round. Don't know how well they work...but some reefers are using it.
