I've been having issues with the ATO setup. Originally I had an optical at water level and a float for emergency shut off. this worked for a long time. however when the return pump is shut off this chamber of the sump is then over filled with water.. and per a past conversation this is a big no for the optical sensors. it was fine for several months but finally died, stuck in the "touching water" state. so for a quick emergency setup i took the contact-less sensor i had on the glass of the RODI container and put that on the glass of the sump. this "works" however this chamber gets very dirty at the water line and i think this is causing issues falsely reading. plus id like to have that back on the RODI chamber. SO!.. any suggestions on how i can resolve this and get a stable, reliable ATO system? would 2 floats work? one for "on/off" and the second for the hard cut off?
