OK...I was watching some video's on making a Homemade Co2 Generator. They used a 5 Gallon Bucket with a Lid, an Aquarium Fish Pump, Aquarium Heater & of course Hose. Inside the Bucket they mixed Water, Sugar & Yeast to create the Co2. It's interesting for sure....but has anyone here ever made a Co2 Generator & if so... 1) Did it work ? 2) What size did you make ? 3) How Long does it last & how often do you have to add or replace the ingredients ? Very interested in this if it works so any & all info is welcomed.....Thanks !!!
