DOS auto water change programming question

[Woodneers]

I have a DOS set up to change 2 gallons a day during the day when no one is home as it annoys my wife. My issue is I’m using 2 20 gallon brute containers as reservoirs. I’m currently watching them and emptying/refilling them as needed. Is there a way to program the apex to send me an alert as the DOS has depleted the 20 gallon reservoir or even stop the awc until I reset it or something. I’ve also considered a float sensor or optical to **** down the process but programming might be quite easier. Right now the containers are on either side of the tank but I’d like to move them to a more out of site location so extra wires that I can eliminate would be easiest. Let me know what my options are if any! Thanks

Your best option is adding float or optical sensors to the containers. The DOS cannot be programmed to stop based on the volume pumped.
