# Is Roebic K-37, K-57 & Bacterial Septic Tank Treatments Safe for Septic Tanks?

Roebic K-37 (Septic Tank Treatment) and K-57 (Emergency Treatment) contain specialized aerobic and anaerobic spore-forming bacteria designed to digest sludge, starch, proteins, and cellulose. While a properly functioning septic tank generates its own bacteria from human waste, Roebic treatments are completely safe and helpful after accidental chemical shocks or prolonged home vacancy.

## Official Wastewater Verdict on Roebic K-37, K-57 & Bacterial Septic Tank Treatments

Certified Non-Pathogenic Bacterial Cultures — Useful After Chemical Shock

- Status: SAFE
- Microbial Rule: Pour directly into the toilet bowl and flush twice before bedtime to allow cultures to populate the tank overnight.
- Primary Risk: Additives cannot replace periodic mechanical pumping; physical inorganic grit and non-digestible sludge must still be pumped every 3 to 5 years.
- Safe Alternative: Bio-Clean Septic Bacteria, Green Gobbler Septic Pods, or routine mechanical pumping.

## Biological & Chemical Impact on Septic Bacteria

Fortifies bacterial populations with specialized spore-forming Bacillus strains without producing dangerous chemical byproducts.

Additives cannot replace periodic mechanical pumping; physical inorganic grit and non-digestible sludge must still be pumped every 3 to 5 years.

Pour directly into the toilet bowl and flush twice before bedtime to allow cultures to populate the tank overnight.

## Frequently Asked Questions About Roebic K-37, K-57 & Bacterial Septic Tank Treatments

### Do I really need to use Roebic K-37 every year?

A healthy septic tank digests waste naturally without monthly additives. However, Roebic is safe and beneficial if your tank suffered chemical shock from bleach or antibiotic use.

### Can Roebic K-57 unclog a failed septic drain field?

Roebic K-57 can break down organic matter in a sluggish tank, but if a drain field has failed due to soil compaction, tree roots, or deep biomat sealing, professional mechanical repair is required.
