After helping out a guy on YouTube, having an issue with a scene he created, I decided to play around with this blend file, and log some more hours in the fluid physics sim.
He was having some issues with fluids disappearing from his scene, after leaving a square pipe and hitting aquarium floor that he had set up.

It took me a few tries to finally realize what was happening...
