s3n8 said:I got a $6 aquarium pump, 8ft of tiny hose, and a 5 pack of disposable air stones. I think it cost 10.99 total. I let it run in the kettle (after it cooled) till it nearly foamed over, about 25 minutes, racked to carboy, and hit it with the air again until it filled the headspace (another 15 or 20). Pitched a nice big starter, and stuffed the blowoff tube in. That was an hour ago. Nothing yet, holding breath.
I still think I will look into getting an o2 setup with a SS stone.
Before you do that, you may want to read this first:

Scroll down to topic #3. Food for though. Perhaps the $10 aquarium pump is the way to go.

By oxgenating the wort instead of the yeast starter, it will cause an over production of cells due to the excessive oxygen presence. This then leads to the production of unwanted esters and higher alcohols that will compromise beer flavor.
When oxygenating starters, you cannot use pure O2... the reason is that the uptake occurs too fast and without a dissolved O2 meter ($$$), you cannot tell when to stop. It is virtually impossible to over-aerate using air, so you will avoid oxygen toxicity problems that will occur if trying to do this with pure oxygen.

So just the aquarium pump, standard small aquarium tubing, and the aquarium diffuser? No in-line filter or anything else?

Yes, but...
I have since retired that setup, and would recommend you get a SS stone and regulator from any of the online brew-supply stores. After reading more, and learning of the difficulty in sanitation of the aquarium stones, I decided not to chance it. I boil my SS o2 stone every once in a while, and toss it in the sanitizer while brewing.
I have a quick question about this .5 micron stainless steel diffusion stone.
Is the stainless steel diffusion part supposed to pull off so easily?
I noticed a lot of bubbles coming out around where it slides onto the threaded part.
Should I epoxy it on?
No, it's not supposed to pop off at all! How old is it? can you contact the place you bought it from and exchange it??
It's brand new, I bought it on ebay from nybrewsupply. I've emailed them through ebay and awaiting their response...fingers crossed...

Just got a response from nybrewsupply;
"Hi, The 2 parts are normally glued together by the manufacturer, A small dab of 5 minute epoxy where the fitting meet should glue it back together just fine. Just make sure not to hold the stone with your hands or the oils can clog the pores..."
Oh boy, maybe it's time to look somewhere else for a SS aeration system ...
How's this "5 minute epoxy" gonna hold up in boiling water???
