Ideal for Pools Up to 50 000 Litres
Each Activator D treatment pack is suitable for pools containing up to 50 000 litres of water.
Recommended Dosage
- Normal maintenance: 1 pack per month for 50 000 litres
- Green or neglected pool: Double dose (2 packs) as an initial shock treatment
- Continue with the standard monthly dosage once the water has cleared.
Using Activator D regularly helps restore even heavily neglected pools to clean, sparkling condition.
Effectively Kills Green and Black Algae
Algae is one of the most common problems pool owners face.
Activator D is designed to combat both green algae and stubborn black algae.
Green Algae
Green algae typically clears within a few days after treatment.
Black Algae
Black algae is more persistent and may take several weeks to fully disappear. Brushing the pool walls during treatment helps the product reach the algae roots and speeds up the cleaning process.
Regular use keeps your pool water clear, blue, and algae-free.
Safe and Easy Pool Treatment
Activator D is known for being safe and easy to use compared to many other pool chemicals.
Key safety benefits include:
- Non-toxic
- Non-corrosive
- Chlorine-free
- Gentle on eyes and skin
The product can even be added while people are swimming, making it a convenient option for busy households.
Another advantage is that Activator D does not react negatively with other pool chemicals, meaning it can be used alongside chlorine or HTH treatments without complications.
Helps Control Bacteria in Residential Pools
Activator D also helps control bacteria under normal residential pool conditions.
For home swimming pools, this level of sanitation is typically sufficient when combined with normal chlorine maintenance.
For high-traffic pools or public pools, additional sanitising treatments may still be required to maintain proper hygiene standards.
Used correctly, Activator D helps maintain clean, safe water for family swimming.
Save Money During Winter
Pool maintenance costs often decrease during colder months.
When water temperatures drop below 13°C and the pool is not in use, Activator D dosing can be paused.
During winter you can also reduce chlorine usage, helping save money while your pool is dormant.
Once temperatures rise and swimming season begins again, simply restart your monthly Activator D routine.
Available Pack Sizes
Activator D is available in multiple package sizes to suit different needs.
Options typically include:
- Single pack – ideal for monthly maintenance
- 10-pack – a full year supply for a well-maintained 50 000 litre pool. Theret is no need to add Activator D during the two coldest months of the year.
Buying larger packs can help reduce overall pool maintenance costs and ensures you always have treatment available when needed.
How to Use Activator D (Step-by-Step)
Activator D is designed to be simple and quick to apply.
1. Balance Pool pH
Before treatment, ensure the pool water pH is between 6.8 and 7.2.
2. Backwash the Filter
Backwash your pool filter to remove debris and ensure proper circulation.
3. Add Activator D
With the pump running and the filter set to filter mode, empty both containers of Activator D into the pool weir.
Important: Do not pour directly into the pool.
4. Brush the Pool
Brush the walls and floor thoroughly. This helps dissolve the treatment and allows it to reach algae growth more effectively.
Brushing also prevents undissolved particles from staining pool surfaces.
5. Continue Normal Maintenance
After treatment:
- Backwash the filter weekly
- Keep baskets clean
- Maintain correct alkalinity levels
6. Add Chlorine After 3 Days
Starting three days after treatment, add 1–3 cups of granular chlorine or Africhem weekly per 50 000 litres to provide additional bacterial protection.
Following these steps helps ensure your pool stays clear, healthy, and ready to swim in.
