Looking for input on Apex advanced code for Klir modifications. Here's the thread: https://www.reef2reef.com/threads/k...ons-to-coralvue-and-faulty-controller.553225/ My post #33 hints at what could be done. Thinking about removing float switch from filter's controller and connecting to BoB. Then bypassing filter controller and having Apex switch roller motor on/off. @ElectricMusic uses OSC command instead of float switch.
