I don't agree, all this blow off tube crap drives me nuts ! You only need a blow off tube cos you put too much in the carboy !
Now you have done it I would take a gallon off into another vessel to ferment out, then experiment with it, add something, hops? Extract ?
Anything, just to get a cleaner environment. Why have all that sticky mess around the place. I reckon that most of the infected brew pictures we see start out just like yours, it ain't right, and it ain't necessary.
