AC3 pro feed function - for water change

[Doo]

I automated my water change using this code and it changes 5 gal/ day and it works great.

What I would like to do now is set it up so it is one of my feed options...
I am having a hard time wrapping my head around it. Any feed back would be appreciated

This is my current program now for the water change...

If Time > 16:10 Then PMP OFF (turns the Pump in the sump off)
If Time > 16:10 Then SKM OFF (Turns the skimmer off)
If Time > 16:30 Then PMP ON (this will turn the pump back on after the water change is done - 20 min duration)
If Time > 16:30 Then SKM ON (this will turn the skimmer back on after the water change is done - 20 min duration)
If Time > 16:21 Then PMS ON (this is a pump in the sump that will send water to the drain for 1 min)
If Time > 16:22 Then PMS OFF (this turns off the pump that drains water)
If Time > 16:24 Then SAL ON (This is the pump in the saltwater drum that pumps water back to the sump)
If Switch1 CLOSED Then SAL OFF (this switch turns the sump in the drum off as well when it hits the proper level in the sump)
If Time > 16:25 Then SAL OFF (This is a safety shutoff for the pump in the saltwater drum)
