## Questions & Answers

**Q: Is this a 100% stainless "stone"?**
A: I've had mine for a while now and can say I've never seen any rust or other material come out of it so I assume it is 100% stainless.The barb and stone exterior are 100% stainless for sure - but unless somebody cuts one open... :)  Anyhow, I've boiled this thing etc - it is really great.  Asside from dropping it or clogging it up with crud somehow, It should last a lifetime.

**Q: Is this stone chemically resistant to strong sulfuric or hydrochloric acid?**
A: Stainless steel is very susceptible to being reduced by strong acids. So I would say using strong acids would not be good for the longevity of the carbonating stone.

**Q: How much air pressure does it take to make bubbles?  Can you make bubbles just blowing with your breath?**
A: About 2PSI, no you cannot blow bubbles with your mouth.

**Q: Will a cheap aquarium pump work with this stone?**
A: Yes, but use an additional filter between the airpump and the stone.  One of the cheap homebrew air filters are just fine.

    Awesome for carbonating water
  

*by S***N on Reviewed in the United States on April 16, 2018*

I use this to carbonate my corny keg of seltzer, and it works amazingly.I connected it to one end of some tubing and put the other end of the tube onto the gas in dip tube in the keg. The stone rests on the bottom.I filled it with water, put it in the kegerator, turned the co2 pressure up to 35 psi (I like fizzy seltzer) and it was fully carbonated in about 3 hours, as opposed to days. Not sure how it would work for beer, but I assume it would work just as good as it did for the seltzer.

    Works just as advertised
  

*by W***N on Reviewed in the United States on January 17, 2016*

I ran a clear plastic tube from the gas inlet pipe inside the top of my 5 gallon cornelius keg to the bottom, and put this stone at the bottom end. I chill the keg down to about 40 deg. F first, then crank up the CO2 pressure to about 30 psi, and although the gas flows very slowly into the keg, it diffuses much more quickly into the liquid than with the old shaking routine. Ready to serve after just a few hours!
