This may be a dumb question but I am going to ask it anyway. When setting up my ATO, does the reservoir tank need to be at the same level as my sump? For example, the tank where my topoff water comes from is higher than my sump. When the pump shuts off water continues to fill via a siphon effect. Is the only remedy to lower the res so it is at the same level as the sump?

Why not have your ATO drip into your display tank? Or take a piece of PVC taller then your reserve water level and have your ATO drip into it? Just need a break in the tubing above water level to break siphon.

Great idea about the PVC. Thanks.
