What are some home remedis I can use to treat my septic tank VS using ridX?

When I was a kid my dad used to flush a dead mouse down every time he had the chance. Later I learned this was more of an old wives remedy that wasn't needed. Now a days all that you need to do is have the tank pumped every so many years. I live in a lake community and we must pump every 5 years, so I thinks that a little more often that the norm. If you are having issues with your septic its too late for even Ridx or a dead mouse.
