Description
ACTIVATOR D — MONTHLY POOL TREATMENT
Activator D is a chlorine-free monthly pool treatment that kills green and black
algae and maintains water clarity. The product comes as a two-part system — a
powder and a liquid (850g total) — that you pour into the weir with the pump
running. One treatment covers pools up to 50,000 litres for a full month.
HOW TO USE
Test and adjust your pool’s pH (6.8–7.2) and alkalinity (80–120 ppm). Backwash
the filter. With the pump running on filter, pour both bottles of Activator D
into the weir — do not pour directly into the pool. Brush the pool well after
adding. Backwash weekly and keep baskets clear for best results. For severely
green pools, use a double dose as an initial shock treatment.
KEY BENEFITS
Chlorine-free and non-toxic — safe for skin and eyes. Does not damage swimwear.
Environmentally friendly — pool runoff won’t harm plants (provided no other
chemicals are used). Can be added while people are swimming. Does not react with
other pool chemicals. Effective against both green and black algae.
SPECIFICATIONS
Treatment size: 850g (1 powder + 1 liquid). Coverage: up to 50,000 litres for
one month. For pools around 25,000 litres, use half of each bottle per month.
