Shopping for a controller, leaning towards the Apex or Apex Lite. I want to be able to at a minimum monitor PH and salinity, and shut off the top off if either goes out of spec. Temp and other stuff would be nice. I'd love to be able to set it up to email me if something goes wrong as well. Thought I'd see if anyone had one or part of a setup collecting dust before I shop for new, as I didn't expect to spend money right now.
