Turn off ATO during water change?

[BTimms]

I’m running a smart dual sensor ATO.

Do you all turn your ato off during a water change to prevent it from turning on?
What do you do with your ATO during water changes?

Thanks!

I just turn off master power to kill the ATO during changes

Yes, turn it off.

Off, my ato runs for 3 hours everyday, topoff is of the whole time.

Here's a tip for those of you who use the Tunze 3155. When doing a water change or when the water level drops during maintenance, etc.. simply use a small rubber band to hold the safety shut float valve in the closed position (up) (as if there's too much water to prevent the unit from turning on). This keeps you from unplugging the unit and restarting it and activating the self priming cycle. When finished with the water change, simply remove the rubber band.
If you have a brightly colored rubber band, then it's a bright reminder to remove it when you're finished.

I probably wouldn't remember, lol.
Apex simply shuts it off and turns it back on for me. 100 gallon system won't miss a beat for that little bit of extra water.

I have water changes programmed in my Apex so I definitely shutdown the ATO along with the heaters, ALK & CA dosing, and Kalk reactor.

110%.
using the sliders on the apex instead of pulling plugs was the main reason i sprung for an apex. 7 years later its been invaluable for that purpose and many others

I just pull the plug for the pump. Not sure how you can do water changes, in a sump, without turning it off.

I have the Duetto ATO on my reef tank. I simply unplug the pump cord but leave the "brain" portion plugged into the wall. That way it can't add freshwater once the water level drops. It starts beeping after a few minutes but after I drain and refill the tank I just hit the button and it goes right back to normal.

With a Sharpie, I wrote ATO on my Water Change hoses. I Just unplug it.
