Reef-pin ATO 2 sensor full level and a fill level sensor

[Wolfw28]

I have a Red Sea Nano witch has a built in about 1L ATO sum-and I have a Pump that pump 200l p/h. picture trying to control the level of water in a one liter bottle with the top cut off with one sensor and a pump the flows 200Lph. My thought was to mount a low level sensor at the bottom of the 1L container and a full sensor to turn pump off that way the pump cycles on for 1-3 seconds instead of for cycling on for millisecond. If I had a dosing pump 1 sensor would be fine. I’m new to Reefpi and robot tank not sure how to setup a macro all my a temp s have failed. Any help would be be greatly April appreciatEd. It such a simple concept

Did the ATO come with the tank or did you add it separately?
