Long-Term Algae Protection for Winter Pool Care
Lo-Chlor Long-Life Winteriser Algaecide is a specialised maintenance algaecide developed to control algae growth during the colder winter months, when pool use, circulation, and sanitiser demand are typically reduced.
Using Lo-Chlor’s proven organo copper complex, this long-lasting formulation helps maintain clear, stain-free pool water throughout the colder months while reducing the need for frequent chemical dosing and extended filtration.
Features & Benefits
- Winter-specific algae control – developed to manage algae growth during cold conditions.
- Broad-spectrum protection – effective against green, black spot, mustard, and pink algae.
- Long-lasting performance – provides algae prevention for up to 90 days.
- Supports chlorine efficiency – helps maintain effective sanitation with reduced winter dosing.
- Reduced winter maintenance – supports shorter filtration times and lower chemical input.
- Non-staining formulation – safe for use on all common pool finishes when water is balanced.
How It Works
Lo-Chlor Winteriser Algaecide uses a unique organo copper complex that keeps copper fully dissolved and stable in pool water, preventing it from dropping out of solution and causing surface staining when used as directed.
This stabilised copper complex provides consistent, long-term algae prevention during winter, allowing effective control even when chlorination and filtration schedules are reduced. The result is clear, protected pool water throughout the colder months with minimal intervention.
Dosage & Coverage
- Dosage: 500mL treats 60,000 litres of pool water.
How to Use
- Ensure the pool is clean and free from visible algae before application.
- Test and balance pool water prior to dosing.
- Ensure pH is within the recommended balanced range.
- With the pump running, add the calculated dose evenly around the pool, preferably near return inlets.
- Run the filtration system as normal for your winter schedule to circulate the product.
- Maintain sanitiser levels within the recommended range throughout winter.
Important Usage & Compatibility Information
- Compatible with recognised pool sanitisers and common pool additives.
- Not recommended for use with ionisers or Nature2 systems.
- Phosphate levels contribute to algae growth — testing and management is recommended after algae treatment.
- During winter, filtration and chlorination requirements are typically reduced — continue regular water testing and adjust run time/output as needed.
- Maintain pool water balance within Australian Standard ranges for best results.
This product is an algaecide and must be used alongside a registered pool sanitiser. Ensure normal sanitising levels are restored and water is balanced before swimming.

Frequently Asked Questions
Why is phosphate testing recommended when using Winteriser Algaecide?
Yes. Phosphate levels should always be tested after adding a Lo-Chlor algaecide. Phosphates act as a nutrient source for algae, and elevated levels can reduce the effectiveness and longevity of winter algae protection. Where phosphate levels are present, appropriate treatment is recommended to support long-term results.
Does this replace chlorine during winter?
No. Winteriser Algaecide supports algae control when chlorine demand is lower, but it must still be used alongside a registered pool sanitiser. Chlorine levels can typically be maintained at lower levels during winter.
Will this help reduce winter pool maintenance?
Yes. By controlling algae growth over an extended period, Winteriser Algaecide helps reduce brushing, shock treatments, and corrective maintenance during colder months.
Is this product suitable for salt chlorinated pools?
Yes. It is compatible with salt chlorinators and can help improve winter efficiency when chlorinator output is reduced.
Can I use Winteriser Algaecide if my pool already has algae?
Winteriser Algaecide is intended for preventative winter protection. Any existing algae should be fully treated and removed before application.
Will it stain my pool or equipment?
No. When used as directed and with balanced water, the unique organo copper complex remains in solution and is guaranteed non-staining.
Can I swim after adding Winteriser Algaecide?
Swimming is safe once the product has circulated, sanitising levels are restored, and water balance is within recommended ranges.
