I'm setting up my 1st reef tank (54g hexagon with a sump below) water is draining into my sump from my return flow tube before I even get my water level up to the teeth through which water drains down to the sump. Is there a one-way vaulve I can attach on the end of the return tube that will prevent water from going backwards? Am I missing an attachment? I would hate to have a fish get sucked down into my pump! Not to mention a flood during a power outage. Any help would be appreciated. Thanks.
