BIOMAGIC Heavy Duty Large Waste Tank Toilet Chemical - 500ml treats the cause of odours and is great for use in chemical toilets as well as having other great uses around your campsite.


BioMagic treats the cause instead of the sympton and works in a far superior way to products that mask or absorb odours. BioMagic provides a practical and economical way of supplying oxygen and nutrients in a hydrated form, which allows the facultative bacteria to quickly become and remain aerobic, effectively eliminating sulfide production and actually preventing odours from being produced. It accelerates the rate of waste breakdown. For neutralising biomass, biomagic acts the same as Mother natures bio-cycle, only hyper-accelerated.

How to use BioMagic for Large Waste Tanks Large holding Tanks: Treat at the rate of 100mls per 100 litres of capacity divided into gradual doses. We recommend you add approx half the required dose for the tank with at least 2-3inches of water in base of tank at set-up. Then add more when the tank reaches half full or 5-6 days. If you only use it sporadically add 50 mls per 2 people per week.In very hot weather Start with half the dose and add 50 ml every 3-4 days when using it.This is due to the fact that the bacteria will use it quicker in the heat.

Porta-Potty or Cassette: Add 30 mls to the flush tank & fill with water. Add 30 mls of Biomagic & at least an inch of water to the base tank . Toilet is now ready to use. If you are not ready to empty it by 3-4 days add another half a dose with a coupe of flushes to keep it active for another few days. Note: Cleaning all old chemical products out is very important. Refer to Changeover procedure.

Greywater Holding Tanks: Empty tank & add 50mls per 100 litres capacity fill with water & soak 4-12 hours. Empty , then add 1 capful down each drain with a cupfull of water. After this add 1 capful each 1-2 days or each day if you are using a shower. It will stop odour, gas & sludge build-up in the tank.

Laundry, Washing Machines: Add 25-30 mls to a wash load with clothes and laundry product (no bleach or disinfectant). It will soften & deodorise the clothes & is beneficial to the machine & drains too.
