M6 Oxygen Tank

[mbaker33]

Hey all,

I've been looking into oxygen tanks and found a few M6 tanks on eBay for $30 or less including shipping. I'm just curious, does anyone know how long an M6 tank will last? It's the smallest tank they sell from what I can tell. I've obviously never used oxygen in my beer before, so I'm not sure how much is used in each ferment.

Thanks in advance!

The $9 red ones from Home Depot last about 8-9 uses for me. I oxygenate at a rolling bubble point for about 90 seconds per batch. In comparing to one time when I was out, fermentation definitely started quicker with oxygen than without.

That's a medical grade tank. I don't think you will be able to get it filled without a prescription. I have an oxygen tank for welding which I can exchange readily at a welding shop.
