DetailsThis stone has less resistance and therefore has an application where you don't want to use tube clamps to attach it to tubing. You can use this 2 Micron Stone to carbonate beer or to create an oxygen system for your yeast. Either way, this versatile stone will make your life easier.
Note: To prevent the pores from getting clogged, Midwest recommends not handling the porous end directly with your fingers.

4.6 / 5.08 ReviewsPerfect for quick carbonationWe use this stone for carbonating water, and it works wonders 50psi carbonated water within an hour. Works fine with 1/4" ID tubing, just be sure to soak the end in hot water firstApril 26, 2013Better aeration than splashingI got a real big Oxygen tank so rather than splashing the wort I give it a minute of pure Oxygen. This appears to have made a difference because my yeast don't slack off at the end and miss the final gravity by 5-6 points.October 4, 2013Oxygenate your wortIt dissolves very small bubbles of Oxygen into your wort. I use it in my Oxygen system. But it blocks easily so never handle it and soak it in a small cup of PBW right after using.January 13, 2014Love it!I got this stone to help my bugs along in initial fermentation of wine, learned that the pump should be running before, during, and after submersion or your product will permeate the stone and hose (more cleaning and hassle). I also use it to aerate while making colloidal silver.March 24, 2012Get some o2 in the wort to make Yeast Happy!We used to just splash the wort around, but now we use medical grade O2 with this stone to make things get start quickly. Run at a 1.5 or 2 (medical regulator) and this stone should bring 5 gallons to saturation in under 2 minutes. Works very well. _x000D__x000D_We boil between uses to keep it clean and never touch the stone with bare hands (oils can clog it). As stated by another reviewer, start the flow of gas before immersing to keep it from clogging. With care, this will last forever.April 1, 2013Makes it easier for Oxygen to get absorbed by the wortThe tiny bubbles of Oxygen are easier to absorb than big ones. Eventually the stone gets blocked up and needs to be replaced. I soak it in Star San but even so, it eventually blocks up.October 25, 2013Overall Good.Works well, doesn't clog like the 0.5 micron. Boil or soak in star-san to sanitize. I use this with a aquarium air pump, and found the barb fitting to be much larger than the aquarium air tubing. I was able to eventually get it on by sticking the tubing in boiling water and forcing it on. This makes it very inconvenient to remove the air stone to boil, so I've kept it on the tubing and soak the whole thing in star-san. I would recommend using this with a larger diameter tubing if you can.April 1, 2013Great StoneThis stone works very well; I've never had it clog. I always soak in star san as that is easier for me than boiling. I use it to force carb in kegs as I cut off the end of a diptube and attached it to that.April 5, 2013
