Lo-Chlor Long-Life Bio-Klenz Premium Strength Bio-Film Remover
Lo-Chlor Long-Life Bio-Klenz is an environmentally friendly, premium strength, concentrated liquid formulated to combat bio-film and support consistently clear, high-quality pool water as part of a simple maintenance routine.
Bio-film is the invisible build-up that forms on pool surfaces and inside circulation lines and equipment. Over time, it can increase sanitiser demand and reduce filtration efficiency. Bio-Klenz works alongside your existing pool care program by lifting this build-up from surfaces and dispersing it into the water so it can be filtered out more effectively.
The result is a cleaner pool environment with improved clarity and a more efficient overall chemical program – which can help reduce wasted sanitiser and support more efficient pool operation over time.

Features & Benefits
- Supports cleaner, clearer, healthier-looking water with consistent maintenance
- Helps reduce hidden sanitiser demand associated with bio-film build-up
- Built-in clarifying action supports more effective filtration of released contaminants
- Helps keep filters and plumbing lines cleaner over time, ssupporting more efficient circulation and filtration
- Supports longer service life of salt chlorinator cells by helping keep plates cleaner
- Supports longer service life of heaters, heat pumps, and solar systems by helping reduce overall sanitiser demand over time
- Supports pool surfaces staying cleaner and smoother with reduced build-up
- Helps reduce turbidity by lowering fine particulate load in the water
- Can help minimise common comfort issues associated with higher chemical load, such as red eye
- Suitable for all pool types and finishes
- Compatible with all recognised sanitisers and pool care programs
How It Works
Bio-Klenz targets bio-film at the surfaces and internal circulation system where it establishes itself.
- Lifts and disperses build-up: Loosens and lifts bio-film and attached particulates from pool surfaces and internal lines so they can be suspended in the water.
- Built-in clarifier action: Helps bind released contaminants so the filtration system can capture and remove them more effectively.
- Works with your sanitiser: By reducing the “workload” created by surface build-up, sanitisers can operate more efficiently on the water itself.

How to Use
- Adjust pH to 7.4–7.8 and total alkalinity to 80–120 ppm.
- Superchlorinate/shock the pool using a sanitiser or a non-chlorine shock.
- With the pump running, add the required dose directly to the pool water in front of return inlets for best dispersion.
- Monitor sanitiser levels over the next 48 hours.
Dosage & Coverage
- Quick guide: Add 1L per 60,000 litres every 4 weeks (monthly).
| Pool Volume | Monthly Dosage |
|---|---|
| 30,000 L | 500 mL |
| 50,000 L | 850 mL |
| 60,000 L | 1,000 mL |
| 75,000 L | 1,250 mL |
| 120,000 L | 2,000 mL |
Important Usage & Compatibility Information
- Bio-Klenz is not a sanitiser and does not replace chlorine or other sanitation systems. Adequate sanitiser levels must be maintained at all times.
- For best results, maintain a minimum of 1.5 ppm free available chlorine (FAC) (higher may be appropriate in hot/humid conditions or with high bather loads).
- Sanitiser demand may temporarily increase after treatment due to contaminants being released into the water – monitor levels closely for 48 hours.
- A small amount of foam may appear during dosing. This is normal and temporary.
- Suitable for all pool types and finishes and compatible with recognised sanitisers and pool care programs.
- Do not overdose. Use only as directed.
- Regular water testing is recommended during use.
Additional Tips
- Cartridge filters: Hose cartridges/elements clean before dosing, reinstall, then add Bio-Klenz. The product’s surfactant qualities can help clean cartridges more thoroughly as it circulates.
- Sand or DE filters: Backwash a day or so after starting the program to remove released contaminants captured by the filter.
- You may not see debris coming from return lines – evidence the program is working is typically seen in clearer, better-feeling water.
- Indoor pools may notice improved "pool smell" as overall system cleanliness improves.
- Tile and vinyl liner pools may see gradual improvement to waterline/scum-line appearance with consistent maintenance.
