any help greatly appreciated!
Level control switch set up in a low level cut off position in the pump chamber of your sump.
If you make sure that there's enough room in your display tank to take the excess should the syphon break and pump stay running until the sump level is low enough to trip the cut off then you're covered. Added bonus of preventing the return pump running dry.
Similarly making sure there's enough room in your sump to take the excess from your display tank should the pump fail and syphon carry on.
You can buy some pretty good level control kits about, get one with 2/3 float switches and you could come up with an integrated ATO and LLCO (level low cut off).
Hope this helps
