I can't reply 100 % as I miles away from my system. Yes I think you can do that, but you also want to turn off the alarm for the auto topup as it will go off if not full.

For your Skimmerand return pump. I turn them off at a feed pause and the auto water change allows a feed pause to be initiated when you start the auto water change.

But if you just want them to stop during the water change, then use water change inverted (I think, pay to experiment) and assign your socket to the programmable logic you just created.
Only problem with this is they will start straight away as soon as the water change is complete.
By using the feed pause I find it is a few minutes more until it restarts.

Sorry not super sure on this as I said I am away from my system for a couple of weeks.

Good luck
