I'm running one bottle with 2 cups of sugar and a half teaspoon of yeast rigged up to a T fitting. One house going in a 1.5g the other into a 2.5 g, using an air stone on the end of the hose sitting under/around the filter inlet underwater so it probably isn't putting much viable co2 in the water itself I'm guessing a decent amount is jumping out of the water
