Maintane 2-Pack 12 Month Supply Natural Septic Treatment

Septic care, redefined.

Maintane is a natural septic tank treatment built around one design priority: zero compromise on what goes into your home, your soil, or your system.

Two ingredients. Six bacterial strains. Twelve billion live cultures per dose. Made in the USA at a biosafety-certified lab, supporting American jobs.

What makes Maintane different:

• For Responsible Septic Owners — Maintane helps support the hidden system your home depends on with a simple monthly routine.
• Two ingredients only — Live bacteria and mineral salt. No fillers, no surfactants, no synthetic binders, no preservatives, no fragrances.
• 12 billion live bacterial cultures per dose — Six named strains targeting proteins, fats, carbs, cellulose, and organic waste. Most competitors don't disclose their CFU count or strain names.
• Biosafety Level 1 classification — The same regulatory safety tier as yogurt cultures and probiotic supplements. Verified non-pathogenic.
• Kid & pet safe — Designed for households with children and pets in mind from day one. No warning labels about contact, no respiratory cautions.
• Made in the USA — Formulated and packaged in a U.S. biosafety-certified lab. Every jar is filled, labeled, and shipped in America. 

The six bacterial strains in every dose

• Bacillus subtilis — Proteins
• Bacillus licheniformis — Fats and oils
• Bacillus amyloliquefaciens — Carbohydrates
• Bacillus megaterium — Cellulose
• Bacillus pumilus — Organic matter
• Pseudomonas putida — Complex compounds

Together, these strains restore the bacterial ecosystem your tank needs to break down waste continuously — every hour, every day.

How to use Maintane

1. Scoop — One level scoop using the included pre-measured spoon. No guessing, no overdosing.
2. Flush — Drop it in any toilet and flush. The powder dissolves instantly, and the live cultures travel through your pipes into your tank.
3. Set a reminder — Set a calendar reminder for 30 days from now. When it goes off, repeat. That's the entire routine.

What you can expect

• Day 1: 12 billion live cultures reach your tank within hours of the first flush.
• Week 1: Bacteria colonize the tank walls. Breakdown of grease, paper, and waste accelerates.
• Month 1: Odors fade. Drains flow cleaner. Your system runs quieter.
• Month 3: Full bacterial ecosystem balance. Sludge builds at a fraction of the untreated rate, extending time between pump-outs.
