BioMagic for Septic Systems

BioMagic in Your Home: Uses in Your Septic System and Beyond

Most people know BioMagic as a caravan or portable toilet solution—but what many don’t realise is that the same natural, oxygen-rich technology makes BioMagic incredibly effective for septic systems, grey water, drains, and entire household biological waste systems.

If your home relies on a septic tank or a whole-of-house waste treatment system, BioMagic can dramatically improve performance, eliminate odours, reduce blockages, and restore the natural biology your system depends on.

Let’s explore exactly how to use BioMagic in your septic tank—and how it can benefit almost every part of your home’s waste network.

 

How BioMagic Works in Your Septic System

BioMagic uses the same simple, powerful principle:
It supplies naturally occurring bacteria with oxygen and nutrients so it can break down waste faster, cleaner and without producing odours or gases.

When your septic tank has enough oxygen and healthy bacteria:

  • Waste breaks down faster
     
  • Odours disappear naturally
     
  • Sludge is reduced
     
  • Drains flow better
     
  • Pipes and lines to and from the tank stay cleaner
     
  • The system handles peak use more easily
     

Instead of harsh chemicals that kill bacteria, BioMagic works with nature, restoring the biological balance your septic tank needs to operate at its best.

 

How to Use BioMagic or Bio-SeptiClean in Septic Tanks

Dosage varies by household size because more people equals more waste in the system.

For 1–2 People

  • Add 100 ml into the toilet and flush
     
  • Repeat every two days during the first week
     
  • After the first week:
     
    • Add 25 ml per adult, per week
       

For 3–6 People

  • Add 200 ml into the toilet and flush
     
  • Repeat every second day during the first week
     
  • After the first week:
     
    • Add 25 ml per adult, per week
       

Children

  • Add one 25 ml dose for every three children under 12, once per week
     
  • Older children count as adults in dosing
     

This process boosts biological activity and cleans the system from the inside out. It also assists in keeping all piping clean and coats the piping to reduce blockages into the septic system. 

 

Why Chemical-Free Matters in Septic Systems

Your septic tank relies entirely on bacteria. Anything that kills or smothers bacteria slows down waste breakdown and creates:

  • Odours
     
  • Sludge
     
  • Blockages
     
  • Poor drainage
     
  • System overload
     

Avoid using:

  • Bleach
     
  • Toilet “blue Loo” products that turn the water blue
     
  • Chemical bowl hangers
     
  • Disinfectants
     
  • Harsh toilet cleaners
     

Instead, look for products labelled “Septic Safe.”
You don’t need special tools or additives—BioMagic simply replaces the biology that chemicals destroy to accelerate the natural process of waste breakdown. It breaks everything into water, liquid compost and carbon dioxide, making it a septic system's best friend.

 

Other Home Uses: BioMagic for Grey Water Systems

Grey water systems benefit greatly from BioMagic because it neutralises detergents and stabilises the water.

Use at approximately 25 ml per 100 litres of grey water.

A great way to dose the system is:

  • Add BioMagic to your laundry wash
     
  • Clothes come out softer and fresher
     
  • The grey water becomes odour-free and suitable for irrigation
     

Just remember: the products you use in your laundry and sink affect the biology of your grey water. The fewer harsh chemicals you use, the better your system will perform.

 

Whole-of-House Biological Waste Systems

If your home uses a full biological waste treatment system (taking all household drains—laundry, bathroom, kitchen, toilet, shower, etc.), BioMagic is your system’s best friend.

Manufacturers of these systems warn against:

  • Heavy chemical use
     
  • Biocidal cleaning products
     
  • Disinfectants
     
  • Excessive bleaches
     

BioMagic helps undo the damage from these products and keeps the system running optimally.

Best Practices for Whole-of-House Systems

  • Use only the minimum amount of cleaning product needed
     
  • Avoid pouring bleach or disinfectants directly down drains
     
  • If bleaching, do it in a bucket and dispose away from drains
     
  • Spray shower cleaners on and wipe off before rinsing to limit drain exposure
     

Adding BioMagic regularly:

  • Increases overall performance
     
  • Removes odours
     
  • Maintains screens & filters
     
  • Helps the system cope with guests or increased usage
     
  • Stabilises the biological “ecosystem” inside the waste system
     

 

Smelly or Slow Drains? BioMagic Fixes That Too

BioMagic isn’t just for toilets—it works wonders on problem drains.

For smelly or slow drains:

  • Add 25 ml BioMagic + 500 ml water down the drain
     
  • Apply once a day for 2–5 days, ideally at night
     
  • Once clear, add a weekly maintenance dose to stop the problem returning
     

BioMagic digests the organic waste and biofilm buildup responsible for most household drain issues—without damaging pipes or septic systems.
