help selecting water sensors


New member
I would like to put a couple water sensors around my sump and displays to provide notification if a tank starts leaking. I'm using a ReefKeeper and would be looking to provide input to the controller via s switch port.

any thoughts on what is a good fit for this?

Looking around:
* I like this: waterbug WB-200 with Honeywell RWD80/T extension cable:
* waterbug WB-200:
* two metal strips through a transistor and relay
* water alarm kit - tap relay instead of piezzo:
*GRI-2800 (not feeling this sensor compared to the cord)
