I just bought a ATO top off system. Its basicaly a sensor you put in the sump.

Now I totaly forgot about gravity when buying this.

My reservoir is slightly above my sump, and it started syphoning my reservoir into the sump even after shutoff.

THen I put the half inch tubing in the overflow, and it syphoned my tank into the reservoir.

Any help on how to set this thing up without worrying about syphoning? I dont have any experience with it.

I have read that the tube you use to move the water from the reservoir to the sump can be placed in a piece of PVC that is in the sump. The tube should then be inserted into the top of the tube so that it will allow the water to fall into the sump, but still be above the top of the reservoir. make sense?

Hmmm. Thanks it does make sense.


I will think on that. I happen to have a nice piece of pvc laying around.
