I am looking into buying a carbonation stone. I see one called "The Stone" advertised at:
formatting link
It says the active area is 2" which is longer than some other ones at
1" however I am not sure about the quality of that 2 inches. For instance, what is the pore size? 0.5 micron, 2 micron? and how effective is this compared to other available stones? Is there a manufacturers web site for this particular model?
Any one have experiences with this one or others? Care to share them? Also, how much CO2 (flow rate) can run through this device. I need one that can handle a gas flow rate of about 0.5 liter of CO2 (STP and 0 Deg C) per minute
Thank you for your assistance.
