and other household products, will determine how well your natural bacteria will thrive or die.

What should and should not go into your septic tank
Besides toilet paper (that's a no-brainer). A good rule of thumb to go by is (If it doesn't go through you first, it shouldn't go into your septic tank).
Raw food (Garbage disposal), wipes of any kind (baby-wipes - disinfecting wipes - etc), condoms, feminine applicators, hand grenades, boa constrictors, unicorns. This list goes on forever. I recommend just using the "Rule of Thumb" It's a lot easier.
