Note: To prevent the pores from getting clogged, Midwest recommends not handling the porous end directly with your fingers.

It 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.
The 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.
I 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.
We 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 first
This 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.
