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: http://www.reefcentral.com/forums/showthread.php?t=2120308
* waterbug WB-200: http://www.reefcentral.com/forums/showthread.php?t=1923119
* two metal strips through a transistor and relay
* water alarm kit - tap relay instead of piezzo: http://www.allelectronics.com/make-a-store/item/MK-108/WATER-ALARM-KIT/1.html
*GRI-2800 (not feeling this sensor compared to the cord)
