Possible infection??

Hi guys,

Hoping someone can tell me that this is ok.

I started fermenting an APA 5 days ago with Wyeast American 2.

Primary fermentation kicked off within 6 hours of pitching and temp was around 18C and has been maintained the whole time. The gravity has been dropping and activity is still very active.

This afternoon I noticed this film of gunk on top in 2 places on top of the krausen. It looks like quite a thick film and I can see it on the side of the carboy hanging down a few cm.

I've seen similar before in previous batches and presume it is break material from the wort, however I haven't seen it formed quite like this before and wondered if I have an infection or mould.

Just so you know, there was a fair amount of break material that went into the fermenter so hopefully it's just that, but wanted to check just in case.
