ActivatorD is a South African-made monthly pool treatment designed to kill green and black algae while reducing reliance on traditional chlorine-heavy maintenance routines. Two bottles (powder and liquid) treat up to 50,000 litres for one month.

How do I calculate my pool volume?

Multiply length × breadth × 1.5, then multiply by 1,000 to get litres. A 50,000-litre pool needs one full treatment monthly; a 25,000-litre pool needs half a bottle of each component.

South Africa's Pool Treatment That Actually Kills Algae

Q: How do I use ActivatorD?

Ensure pH is 6.8–7.2 and alkalinity is 80–120ppm. Backwash the pool. With the motor running and the valve in filter position, empty both bottles into the weir — do not pour directly into the pool. From Day 3, add one cup of chlorine weekly.

Q: Does ActivatorD kill bacteria?

Yes, to a certain extent under normal conditions. However, it does not kill E.coli, so weekly chlorine supplementation is recommended for high-traffic pools. ActivatorD is an algae control treatment, not a standalone sanitiser.

Q: Can ActivatorD be used with other pool chemicals?

Yes. ActivatorD will not react with other chemicals already in your pool, so you can use it immediately without waiting for other chemicals to clear.

Q: Does ActivatorD contain copper?

Yes. ActivatorD contains copper sulphate pentahydrate and zinc sulphate — the active ingredients that target algae and bacteria. The formula is safe for swimmers when used as directed.

Q: Can ActivatorD be used as a shock treatment?

Yes, but do not exceed the dosage of one set of bottles per 50,000 litres per month.

Q: Does ActivatorD work in a jacuzzi or spa bath?

Yes. Add just a tablespoon from each bottle and the water in your jacuzzi or spa bath will turn clear. Scale the dose proportionally to your jacuzzi's volume.

Once a month. Copper + zinc algae control. No chlorine in the treatment itself. While load shedding turns every other pool green, yours stays blue.

Why Your Pool Keeps Going Green

Other chemicals bleach algae.
ActivatorD kills it.

There's a reason your pool turns green every month even with chlorine in it. The algae was never actually killed.

❌ Chlorine & Traditional Chemicals

Hides the problem. Doesn't fix it.

Chlorine bleaches algae so it looks clear, but the algae is still alive in your water and on your pool surfaces. Give it a warm day, a power cut, or a missed treatment and it's back.

❌ Bleaches algae, doesn't destroy it
❌ Weekly dosing required
❌ Red eyes, skin irritation
❌ R300–R600/month in chemicals
❌ Green pool returns after load shedding
❌ Degrades quickly in SA heat

✓ ActivatorD Formula

Actually kills algae. Once a month.

The powder and liquid combined contain copper sulphate pentahydrate and zinc sulphate, which target the algae itself, not just its colour. Your pool surface stays clean. And when the power goes out, there's nothing left to bloom.

✅ Kills algae cells permanently
✅ Once-monthly treatment
✅ Copper + zinc algae-control formula
✅ From R235 per treatment (50,000L)
✅ Load shedding resilient
✅ SA-made and 15 years proven

Simple as 1-2-3

Five Minutes, Once a Month

No complicated schedules. No weekly chemicals. Just three steps between you and a blue pool.

🧪

Balance Your pH

Ensure pH is between 6.8–7.2 and chlorine is at 0ppm before applying. A quick 5-minute test is all it takes. ActivatorD works with your existing water chemistry.

💧

Pour & Activate

Dissolve the powder, then add the liquid through the weir/skimmer. Run your pool pump for 6 hours. The copper and zinc sulphate formula gets straight to work on the algae.

✨

Watch Your Pool Go Blue

From Day 3, add one cup of chlorine weekly for sanitation. That's it. Your pool stays clear for a full month, through load shedding, heat waves, and rain.

Why ActivatorD

Built for South African Pools

15 years of refinement for our climate, our load shedding, our water. Not imported from somewhere with different problems.

👨‍👩‍👧‍👦

Gentler Monthly Routine

Used as directed, ActivatorD helps you move away from repeated chlorine-heavy shocks and panic dosing. That means less chemical smell and less irritation for many families.

🗓️

Once a Month. Not Every Week.

One treatment per month is all it takes. Stop the weekly chemical juggle and the constant trips to the pool shop. Five minutes, once a month.

🚫

No Chlorine in the Treatment

No chlorine in the treatment itself. From Day 3, one cup a week is all you add. Most conventional pools need far more than that.

🦠

Kills Algae. Doesn't Just Hide It.

ActivatorD kills the algae. Chlorine bleaches it so you can't see it. That's why green pools keep coming back with chlorine, and why ActivatorD pools usually don't.

SA-Made & 15-Year Track Record

Developed by Dudley — a pool professional — alongside two chemical engineers, specifically for South African conditions. Used in schools, hotels, and resorts.

⚡

Load Shedding Resilient

When Eskom cuts the power and the pump stops, conventional chemicals degrade fast and algae blooms overnight. ActivatorD keeps working. No green pool waiting for you when the lights come back on.

Frequently Asked Questions

Everything you need to know about ActivatorD and how to get the best results from your pool.

What is ActivatorD?

ActivatorD is a South African-made pool treatment that kills algae rather than just bleaching it. Two bottles (a powder and a liquid) cover a 50,000-litre pool for one full month. No chlorine in the treatment itself, non-toxic, non-corrosive, and environmentally friendly. Most pools clear up within a few days of the first treatment.

How do I use ActivatorD?

Before applying, ensure your pH is between 6.8–7.2 and alkalinity is 80–120ppm. Backwash the pool. With the motor running and the valve in filter position, empty both bottles of ActivatorD into the weir (don't pour directly into the pool). Resume normal pump cycles and watch the water clear. From Day 3, add one cup of chlorine weekly for sanitation.

How do I calculate the volume of my pool?

Multiply your pool's length × breadth × 1.5 to get the volume in cubic metres, then multiply by 1,000 to convert to litres. For example, a 10m × 5m pool = 10 × 5 × 1.5 × 1,000 = 75,000L. A 50,000-litre pool needs one full treatment per month. A 25,000-litre pool needs half a bottle of each component per month.

Does ActivatorD kill bacteria?

Yes, to a certain extent under normal conditions. That said, ActivatorD doesn't kill E.coli, so weekly chlorine is still recommended, especially for busy pools with lots of bathers. Think of ActivatorD as your algae treatment and chlorine as your hygiene top-up.

Can ActivatorD be used with other pool chemicals?

Yes. ActivatorD won't react with other chemicals already in your pool, so you can use it straight away. The usual safety rules still apply: never mix pool chemicals together outside the water, and keep all pool products out of reach of children and animals.

Does ActivatorD contain copper?

Yes. The active ingredients are copper sulphate pentahydrate and zinc sulphate, which target a wide range of algae and bacteria in your pool water. Safe for swimmers when used as directed, and the copper levels stay well within what's acceptable for regular pool use.

Can ActivatorD be used as a shock treatment?

Yes, ActivatorD works well for clearing a badly green pool. Just don't exceed one full set of bottles per 50,000 litres per month. For very large or heavily affected pools, give us a call and we'll help you work out the right amount.

Does ActivatorD work in a jacuzzi or spa bath?

Yes. Add a tablespoon from each bottle and the water in your jacuzzi or spa bath will clear up quickly. Use the same proportional dosing as for pools, scaled down to your jacuzzi's actual volume.
