i get $10 ones from a local hardware store. they aren't refillable but they last for awhile and are cheap. you're going to spend the same amount, might as well get straight 02.
Why not reliable? That doesn't sound good!
i said refillable :fro:
Why not refillable? That doesn't sound good! How much are the ones from most HBS's?
i get mine from lowe's, they are $10. the hook up with aeration stone was like $50 from the LHBS but as we all know, their stuff is usually over priced. i am lazy so i paid it, it came with a medical grade filter so meh. i'm sure a smarter man than me could just buy a stone, a filter, the hook up and some tubing for half the cost.
I wonder if the filter, tubing, and stone that I use with my aquarium pump would work with it? I might have to look into this tomorrow..
my stone is 0.5 microns, if that's any help. you've got to wear gloves to handle it (or just make sure not to touch it) because the oil in your hands will clog it. the filter i think is more of a pain in the ass than it's worth, if you get the filter wet it clogs the whole operation and i really doubt that canned 02 is bad for your wort.
edit - yeah you just need 60-90 seconds to hit 10ppm and that's going to be good for anything you're doing. if you're doing a crazy barleywine or something you should hit it again after 12 hours but this is the only way to get to 10ppm that isn't breaking your back dumping from bucket to bucket for 10min.
I'll have to find out how many microns mine is rated at.. I have no idea.
I have aquarium air pumps laying around and have thought of using them before. How do you test oxygen absorption from using an O2 tank or other method?
I saw 8-10ppm mentioned. What is a standard target for O2 levels prior to fermentation?

I just found an O2 meter for $800.00, so I don't think I'll be testing my wort for saturation levels any time soon!

That's very helpful. Thanks. I like the sanitized bucket idea, any extra measure is worth it. I was also going to use a couple of grain bags folded over many times over the inlet of the pump. I figure that will take care of any dust and other larger things.
Will do. Just soak in my sanitizer and use wet?
