You should be able to use macros, if you use timers the macros can have multiple steps however do not that you need to put the steps in reverse order and click the reverse checkbox in macro, a little quark within reef-pi. Another thing to note if you use sensors to trigger macros you can only have one step in the macro.

I think if you create one macro to turn things off and startup the pump then use two other macros with the sensors to stop the process. Here's a link showing how to use ATO sensor to do a water change.
