ATO by Neptune DOS .??

Is it possible to set up an auto water top off with The Neptune dos?

I have a friend that just figured out how much water evaporates and set his dos to compensate. He makes a couple adjustments a year when humidity changes for the seasons. It actually keeps up very well.

That’s awesome. That’s what I’m trying to accomplish. Do you know how he figured out how much his tank evaporates?
and how he set it up through the Apex?

My ATO DOS schedule attempts to top off 1 gallon every hour. I have two optical sensors in my sump return chamber set at exactly the same height. Added code to the DOS to turn off when both sensors are closed (IF L_ATO CLOSED Then OFF, IF R_ATO CLOSED Then OFF). So both sensors would have to fail at the same time to ever have an issue. The DOS schedule tries to turn on the ATO every 10 minutes to delivery approximately 600ml to the return chamber. Most the time it never turns on due to the code mentioned above. This accommodates for all varying evaporation rates, such as seasonal changes in temperature, daily changes due to lights being on, etc. The RODI comes from my 65g storage tank, so I don't need to worry about refilling a reservoir. The above has worked like a charm for me since I setup my RSR 750 a year ago.
