Aerating stones
« on: February 02, 2010, 08:25:12 AM »
Hi

I am awaiting the arrival of an aeration system using Oxygen.  I now recall having read somewhere that people had trouble keeping the 5 micron stone submerged.

Is this true, or did I just make this up?  If I did not, any good solutions?

Thanks

I have a friend who uses a fishing weight (Non Lead type).

I've not had that problem.  The tubing from the Hepa filter is fairly stiff and stays down fine.  I saw one person who had wrapped some copper wire around a flimsier tubing and that was cool, because it was very straight and he could move it around the wort if he wanted.

You could us a dip tube from a corny keg. Connect the stone to the tube and the hose to the other end. I did that and it stays down. I sometime whisk it around while feeding oxygen.

I aerated with a fish tank pump, with filter and diffusion stone. Didn't seem to make a bit of difference than when I didnt. I chill with a counterflow , with valves full open, and splash down through a funnel and filter, then a little sloshing when I add the yeast.  I believe I have a decent amount of oxygen, as I get some very active fermentations, blowing out the top of my carboys regularly.

Have any of you used a dissolved oxygen meter with a tank pump?  I'd like to buy one, but they are pricey.

I just give the yeast wort in the fermenting bucket about 1 minute of oxygen. I also use yeast nutrients to make sure the "yeasties" are happy. I can't say that my fermentions are any more vigorous than before. I just always get more consistent fermentions. (No stuck or long waits). A meter to check oxygen levels would be overkill. Shaking a carboy sitting on a tennis ball works great for some people! Not for me.
