We've lived in the city all our lives. Even growing up, as I moved around with my parents, we lived in large cities with full city sewer and water, so I never had to help with anything involving a septic tank or overheard my parents talking about how to take care of it.
Flash forward to now and we have the farm, with its small septic tank. Only one shower, one toilet, and no dishwasher, washing machine or disposal. I've of course learned what can't ever be put into a septic tank and, from the above picture, how it all works and is all connected together

My question though is this: What SHOULD we put in there to keep it healthy?
I see all sorts of stuff on the market, name brand things that all say they are the "best product to use". Then I've read online that just plain old yeast is good to flush down the toilets periodically, or a mix of yeast and sugar.
