That looked like a dumper right off the bat. This is one of main reasons I ferment in glass carboys... surprises! I like to see fermentation, high krausen, flocculation, etc. It won't stop an infection but at least I'll get the bad news sooner. Since I have at most two beers going at once and normally just one, I check them here and there. There's something to be said for watching the fermentation process and knowing what it looks like. How different yeast strains behave, etc.
Got to have that airlock! A little star san diluted filtered water won't hurt the beer if some would happen to get in. An irish red shouldn't take long to ferment. I would think sitting in the fermentor for a couple of weeks (probably be done fermenting in a week) and then bottle conditioning them for 3-4+ weeks would be just fine.
