Secondary fermentation

So I am brewing a ale. Once I transphered to secondary fermentation the heater I was using stopped working so the tempiture fell below 65. It has bein sitting at that temp now for about two weeks and I've noticed a thin almost white film over top of the brew. Could this just be protines coagulating because of the cold temp. Or could the batch be spoiled

Infections kind of look like dusty bubbles. Hop oils also can leave a film on the top of your beer.

That looks like the start of a pellicule to me, so it is probably infected. How does it taste/smell?

That's definitely infected and probably not because your heater failed. You should toss the airlock and bung in the garbage to be safe and give that carboy the cleaniest clean you've ever cleaned. Hot oxyclean or PBW with a good brushing for sure.

So assuming the infection was caused by the carboy then that should take care of it, but you might want to replace any siphons and tubing as well.

Also, you may want to replace your racking hose and give your racking cane or auto-siphon an extreme clean as well.

What's your cleaning/sanitation process?

That definitely looks like a Brettanomyces pelicle. I've cleaned some of my glassware with a 24 hour soak in warm noble grape pink cleaner followed by a good soak in star-san and the Brett still survived. PBW might work against it. Definitely replace any plastic that came in contact with it.

I hear 10:1 bleach might work as well
