only on initialization...after it stays.

its C++, so all those functions you see that start with ReefAngel are part of that class. loop() is where you would call your own functions from. take a look at my ino(thread in my signature) for how i do just that. think loop() like main()

I have the rf expansion which is short for radio frequency. It can control vortech pumps. You can modify it pretty easily to control wp40s.
