I use a plastic 'Ale Pale' for Primary and secondary. Is this ok. I see alot of folks use a glass carboy for secondary. I do plan on getting a couple soon.
Are they the same size? I am far from an expert, but I think that size would be the biggest question, as secondaries are usually smaller to reduce the amount of oxygen exposure for the beer.
That said, my guess is that your beer will be just fine.
