My LFS recommended that I get an electric float switch to put in my refugium in order to turn off the pump that will pump water to the refugium if the return gravity-based siphon fails. I've been to a few home depots and they don't carry these switches, and the ones I've seen online (at BRS or Drs Foster-Smith) are running around 0 and appear to require that I rewire the pumps to get them to work. I'm handy, but not sure I'm that handy! Ideally, I'd love to find an electric float switch that works similar to a GFCI plug adapter, where when water reaches a certain level, the circut is tripped and shuts off anything that is plugged into the adapter. Does anyone know if something like this even exists? If not, any suggestions for how I can set up a float switch to shut off pumps that won't require cutting the cords and rewiring my pumps? I am such a novice when it comes to this kind of thing!\n \nThanks!
