Yes, if you have a tank larger than about 30 gallons, two bottles would be better. Some people use the gallon juice containers with success.
I would recommend that you stick to the quantities, more or less. They optimize the food/yeast ratios fairly well. Too much yeast uses up the sugar more quickly, but produces more CO2 in a shorter time. Too much sugar and not enough yeast will produce only a little CO2, but for a longer time.
You certainly don't want more volume than about 2/3 full for a bottle, or you risk having a problem with getting yeast into the tank. |
