ok so now I am an expert and too much oxygen is bad for your wort, doh!

Just make sure you get the right cylinder. Aerating your beer with acetylene could make for some explosive off flavours.

Pure oxygen isnt exactly flame friendly either

Dr.Jacoby sent me some info from the"yeast" book.  You need a flow meter with your o2 to measure your addition. If I remember correctly I think 60 seconds at a flow rate of 1 litre per minute gives 9 ppm in 5 gallons & 120 seconds at a flow rate of 1 litre per minute gives 14 ppm. Im open to correction though as I dont own the book.

Via St.Fursey -> You could always skip aeration altogether & just add a pin head drop of olive oil to your yeast starter!

General consensus for an hour on the net seems to be 60 seconds or 90 for a high gravity using a 2 micron stone and at a rate where the oxygen is going into the wort rather than bubbling out or making excess foam.
I have to find myself an oxygenating wand rather than stone and tube this side of the pond, anyone seen one?
I think those big tanks are overkill and one of the disposable 02 tanks with a small reg will go 12+ doses.
Damn I wish I had it for the RIS barrel!

I bought a ss .5 micron stone & tube from homebrewstuff on ebay.  Stuck the tube inside a dip tube I had from my keggle conversion. Bingo! 

I just mailed SciChem (from dr.jacobys thread on aeration/o2) about prices on the 110 litre tanks & regulators. I asked for a price on a few different quantities incase there is interest for a group buy. Once they get back to me il post the price list.

Apologies for hijacking your thread Rossa. Maybe we should merge the aeration posts with Dr.Jacobys original thread?
