What values do I want here so my auto top off will shut off if my pH rises too much? I use kalkwasser and I just want to be sure if it gets stuck on it'll shutoff when my pH spikes above a certain point.

You don't want to use that wizard for your ATO. Use the Advanced mode and enter your ATO code by hand. It should look something like this:

Set OFF
If Switch1 CLOSED Then ON
If pH > 8.3 Then OFF
Defer 2:00 Then ON

Switch1 is your ATO float. Rename as necessary.
pH limit can be changed.
The Defer is just to keep the ATO from cycling ON/OFF if the float bounces due to water movement.

I just have my jbj ATO plugged into my apex power bar, so I don't have individual float control.

OK. The wizard still won't work for you though - it's for a CO2 unit - it turns the outlet ON at the high pH and turns the outlet OFF at the low pH.

Using 'advanced' mode, just add this to the end of your ATO outlet program:

If pH > 8.30 Then OFF

change the pH value to whatever you want.
