which air stones suited for co2

[misopeenut]

i just made one of those DIY yeast co2 and im using a wooden chop stick as the air stone.
i've tried using the air stone that i used for aeration but the bubbles are too big.
whoever that has CO2, could you tell me which stone or what you use for co2
thanks

You need a micro bubbler or a wood one, here:

AP Rena Ceramic (the one I use, but I haven't tried the wood ones yet)
http://www.bigalsonline.com/catalog/product.xml?product_id=19795;category_id=1627;pcid1=1623;pcid2=

On sale at Drs. Foster and Smith
http://www.drsfostersmith.com/Product/Prod_Display.cfm?pcatid=3722&N=2004+113405

They come in 2", 4" and 6"

Buy at least two of them as you will need to clean it periodically by soaking in hydrogen peroxide for 24 hours.

Wood ones (Big Als, I think, has wood ones too):
Lee's

Coralife Limewood

I've read limewood is best and trying those is next on my list

PS
Make sure you put a wash bottle between the reactor and the diffuser or you could get the yeast solution in your tank. You don't want that.
