Stopping the Sump/Refugium from Overflowing

[honey1998p]

Hi all,
Well the overflow is working in the sump/refugium. All the advise said make sure that the sump/refugium doesn't overflow incase of powerfailure. Well guess what? It does overflow. I tested it out cutting the pump on and off and if left unattended it will overflow on to the floor. How can I adjust it to make the flow stop during poweroutages? I'm new to this, and don't want to make a huge mistake or mess

Thanks all in advance,

a little more info on like size of sump /overflow and details on layout and I can probably help you

Reduce the water level in the sump so that when it does begin to drain when the pump is off, the amount of water that drains from the display will not overflow the sump. If however you have baffles that are x" high and the water has to be above these to flow through the sump, your stuck with coming up with some way to reduce the height of these baffles.

I'm having a similar problem with one of the tanks I just finished setting up... But it's the return plumbing that the water is draining back into the sump thru.. (this tank is drilled).... The return hole is at the same height as the overflow holes, but the overflow holes have the cage/overflow to prevent excess water drainage... I was thinking of getting some sort of check valve to put inline from the return pump, is that a feasible solution? Does such a thing exist? If it does, is it called anything special, or just a check-valve? Thanks...

Just a check valve. Put it inline in your return plumbing close to the output of your pump.

Thanks for the info.

Thanks for the info.

You can also just drill a small pilot hole (1/8") in the return assembly in the aquarium. This will break the siphon in a power outage situation, and should give you enough leeway to prevent overflowing your sump.

Check valves will often leak back over time unless you spend a lot of money and then they slow your waterflow.

You need to drill a 1/16 to 1/8 hole in all your pipes that flow into or out of your tanks right at the water line or a tiny bit lower. This will immediatly stop the water from siphoning all over your floor.

just make sue to keep these cleaned, cause if they clog you are screwed again..
