Hi,
I just started using an Oxynator with one of those red disposible O2 tanks from Lowes. I have been turning on the O2 for 15 seconds, then turning it off and waiting for the foam to settle, then turning it on for another 15 seconds for 10 gallons of wort. Does this sound like an adequate amount of time? I have done this with about 10 batches, and on my most recent batch I noticed significantly less bubbles. Is it possible that I am running out of oxygen in the tank ( i have no idea how long it should last) or is possible that my stone is getting clogged? I usually just soak the stone in sanitizer for about 10 min then store in a plastic bag after each use.
Does anyone know if it is possible to use a refillable oxygen source with the Oxynator? Thanks!

Probably running out of oxygen. Those things don't give ANY warning as far as how heavy they feel, they just run out *poof!* <- like that.

Keep two on hand at all times, when one runs out, you'll have a backup. Just be sure to replace the backup right away

Actually they do. If you have a scale that reads in grams (which you should) You'll need to weigh a full one first, then you can occasionally weigh it again to see how much oxygen you have left.

If you have to stop after 15 seconds due to foam, it's an indication that you're running it WAYYYYY too fast. You should easily be able to run it for 60 seconds with just a small head on top. All those big bubbles on top are full of o2 that is NOT going into the beer.

I will add, if possible to do so, rock or agitate the fermenter after aeration to incorporate some of the O2 that is in head space.

I don't doubt that it registers a difference on a gram scale, I'm just talking about how they feel. I've had a full one in one hand and an empty one in the other and couldn't tell the difference, so when grabbing one out of the closet there's definitely no "red flag" that it's getting near empty.


As far as weighing it, that's far too much trouble for my lazy *ss. At only 8 bucks a pop, I find it far easier to just always have a backup.

I realize that I quoted you, but my post was directed towards the original poster. My point is, there is a very easy way to tell how full the tank is and when it's almost empty. If your to lazy to put the tank on a scale, then that's something you have to deal with yourself.

I echo what Bobby said...if you get too much foam in 15 seconds, you've opened the valve too far.

I barely trickle the O2 into my wort, and just move the SS airstone wand all over the bottom.
I barely see the bubbles breaking on the top...which means most of the O2 is dissolving into solution...the goal of this process.

I trickle in the O2 for about 30 seconds and just barely have foam forming at that point.
I tend to get a little more lag as the yeast consume the O2, then a massive and fast primary/active fermentation (even at 64F with ale yeast) for 2 days and then I'm usually at FG.

I've used the oxynator on MANY batches and have not really noticed a big effect on the final gravity, therefore I've stopped using it because those small tanks were getting expensive and annoying to keep buying.
