Diy sumps.

I think i figured out a way to build a sump wanted to know if this is right? Take a hose and siphon water from the top of the tank to the sump
then have a pump pumping water to the tank from the sump?

Don't forget the overflow box!!! This is how you will get the water out of the tank without draining the tank,and flooding the room.
