Yes. Septic tank bacteria-killers are largely chemicals & cleaners, particularly ones formulated with bleach and/or ammonia. No.2 has neither and is made with alcohol from sugar cane - all natural with no synthetic fragrances at all.

This is based on personal preference, but customers typically dispense between 1-2 pipettes each use. A full pipette is about 10 drops, or when the No.2 Co liquid fills the entire glass stem of the dropper.

They're coming VERY soon. Hold on to your bottles!
