Clarkey Posted August 14, 2005 Share Posted August 14, 2005 I've been trying a DIY CO2 generator but have noticed that the production is fairly slow. In googling I found that colder temperatures retard the yeast growth and i found that some yeasts used for brewing have a lower temperature threshold. One article I read said that the yeast mix gave off Sodium. I am wondering if the Sodium could cause problems with the fish?
