Query: What scent?

Followed directions, smelled nothing, Doubled suggested amounts and still nothing unless you sticking your nose in the exhaust vents of the humidifier, stand up, and smell nothing. ALSO, for first time in 3 years with this humidifier I have what looks like hard water buildup on bottom of the tray, never built up before only now when using the smell sweet junk that doesn't work..... Can't be positive, but I'm blaming it on this stuff.Waste of money, I have one of those automatic air freshener's and just stuck one of them in front of the humidifier, when it goes off the humidifier pushes the scent all around the room, works for me.
