Greetings! Has anyone seen the new "Carbo-Plus" CO2 generator? It makes CO2 by an electrolytic reaction between a carbon brick and water, creating oxygen and hydrogen. The carbon released combines with the free O2 to produce CO2. They say it produces .29 grams of CO2 per hour. Is anyone using this? It's advertised in the early summer Pet Solutions catalog. Just curious. Morgan Gerk Milwaukee, WI
