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.
