I know this is kinda of a ambiguous question, but i figure i would try anyone.
What is the best DIY CO2 recipe, I want to make it last as long as i can. I plan on using a 2L soda bottle, unless there is something better? I have a nano diffuser coming and this is all for a 10 gallon with a power filter. Ive read so many different recipes, sugar, brown sugar, yeast, baking soda, molasses? I just want one that is easy and works for a good time! Please and thank you!
