The "Trickle tickle"?

How long did it take for YOU to get the "Trickle Tickle"?

For those that don't know it. The tickle is like the spidey sense of the reefing world. Its an inane ability to hear trickling water that is out of place in your environment and typically means something is clogged broke or leaking. It can pull you out a dead sleep from two floors away... You just feel it...

for me, it was in my youth in creating a coil filter from an old boat coolant barrel. The plumbing was set up with no breather, which meant that the barrel which sat about 3 foot taller than the sump tank would have a siphon lock the moment it was full and 30 gallons of water would then siphon out of the barrel and into the sump and then onto the floor.... My dear mother did NOT kill me... Though she would have been better off had she...
