NoFlex Digestive Sewage Treatment — 475g
Maintain a fresh, odour-free marine sanitation system with NoFlex Digestive Sewage Treatment. This 475g formula uses natural digestive bacteria to break down waste in marine holding tanks, reducing odours at the source and keeping your onboard sanitation system operating cleanly and efficiently. Trusted by boaters who demand reliable, environmentally responsible waste management at sea.
Key Benefits
- Biological digestion — active bacterial cultures break down solid waste and organic matter in holding tanks naturally
- Odour elimination — targets the root cause of sewage odours rather than masking them with fragrance
- Safe for marine systems — compatible with standard marine holding tanks, hoses, and MSD (Marine Sanitation Device) components
- Environmentally responsible — biodegradable formula minimises environmental impact during legal overboard discharge
- Easy to use — simply add the recommended dose directly to your holding tank via the toilet
Ideal For
Sailboats, powerboats, and any vessel equipped with a holding tank or marine sanitation device. Particularly valuable for extended passages, liveaboards, and cruisers spending time in no-discharge zones where tank hygiene is critical.
Usage Tips
- Add treatment after each pump-out for best results
- Use regularly throughout the season to maintain active bacterial colonies
- Store in a cool, dry location away from direct sunlight
