Hello,

I have a red sea reefer and the overflow box has a silent descent tube + the "emergency box" would it be possible to have two level sensor in this overflow box to regulate the pump speed and adjust the rate ( within specific boundaries) to keep the overflow box level within the silent range.

As the regulated descent speed is not always constant. Could still need a flow sensor.

Let me know what you think of the idea ( or how it could be implemented )
