Mold in Carboy

[Holmesbrewer]

Yeah, I have looked thru the threads, but didnt find my answer....
I had a nasty looking film with spores on top of my Wee Heavy in the secondary. I assume it back packed on something not cleaned properly.
I racked the beer out from under the film into a new properly sanitized carboy and added one campden.
After a few days, its back. Added another campden.
It's a 5 gallon batch. How do you know when you have killed it? And if you kill it, dont you kill your yeast too? I dont keg, so how do I carbonate if the yeast is dead?

By what process did you "rack the beer out from under the film"?

Sanitized cane, slid thru the film to near the bottom of the carboy, drew out all but the top few inches.
My understanding is the bacteria is thu out the beer, the film is just the indicator.

If you slid the racking cane through the layer of mold, then you pushed some mold down into your beer and sucked it into the other carboy.

Seems likely to me.
