Re: [APD] CO2 not dissolving

["S. Hieber" <shieber at yahoo_com>]

It whould have to be impure with something that doesn't
dissolve readily in water. I wouldn't put my money on it.

It wasn't clear why the gas is in the reactor, accumulation
or not.  CO2 levels will tell a lot. If the CO2 levels are
properly responsive to the injection, then the problem is
more like too much gas -- and perhaps too mcuh CO2 with a
lot being shed quickly, or a air leak in the system.

Novices and experts alike show their skills. Past winners have been
novices and experts, too. You can view all the entrees at The 5th AGA
