I dont have a kegging system yet, so I dont have a c02 tank, but I want to be able to lay down a layer of c02 on my beer after racking it to my secondary. I have access to a paintball canister, but dont know what type of connectors or hoses I would need.

Any help would be appreciated.

Why would you do this? The yeast that is in the beer already will take care of this for you.

Well after racking to the secondary there is none there for a small amount of time. During this time it would be exposed to oxygen. Also I may be getting a 14 gallon conical from a friend, and will still only be doing 5-6 gallon batches, and would want to throw down a layer of C02 at the begining of fermentation.

If you are wanting to do this to prevent oxidization, I wouldn't worry about it. After racking, enough CO2 will come out of suspension to displace the air in the small void in the top of the carboy. In fact, even though fermentation may be complete you may see some bubbling of the airlock after transferring due to the CO2 coming out of suspension. If you absolutely must try please remember that carboys are probably not the best container to hold pressure, so use a very low pressure and allow excess air and co2 a means to escape.

Im not talking about pressuring them at all. CO2 is heavier than air and will just sit on top of the beer.

So I would rack the beer, "pour" a layer of CO2 on top of the beer, then place on the airlock.

It may not be needed as much when I rack to secondary, but If I use the big primary conical I might.

Does anybody know what type of dispenser or valve I would need.

At the beginning of fermentation, you want the O2, so I don't think you want to add CO2 at this point. My understanding is the extra headspace is only an issue during secondary.

Maybe I was just confusing something I read somewhere.
So a five gallon batch in a 14 gal fermentor shouldnt cause problems?

If it were THAT risky we'd be doing it all the time. There is a certain amount of co2 already in solution from fermentation, and that's coming over with your beer, and it's going to kick up on it's own and further protect it.

Your beer is not that "sensitive." It can handle being in secondary, and being racked to secondary. It can handle just about everything we do to it in the normal course of brewing, and even making mistakes.

Although I'm not a big user of secondaries, but folks have been using it for centuries without having to do anything "special" to have the already present co2 protect the beer/wine. And have stuff in secondaries for months if not years. I've have to, and never saw the need to add more co2 to it. And never had any issues.

It really isn't crucial to do this.

I ferment 5.5 gallon batches in a 16 gallon Sanke keg and I don't use a secondary.

Now that I think about it, I saw this on a youtube video, and it was when the guy was transfering to the keg, he "poured" some c02 into the keg before racking the beer in. Somehow I got things confused.
