Your septic tank relies on billions of naturally occurring bacteria to break down solids and prevent clogs. Without these bacteria, waste builds up faster, leading to odors, backups, and costly pump-outs. Unfortunately, many household habits—like overusing bleach, antibacterial cleaners, or harsh chemicals—can kill off this essential bacterial population. The good news? You can increase bacteria in your septic tank naturally with a few simple changes, natural treatments, and septic-safe products. This guide covers the best natural ways to boost your septic bacteria and keep your system running smoothly.
