The product comes in two bottles – a powder and a liquid – totalling 850 grams. This is enough for a 50,000-litre pool for one month. It is safe, environmentally friendly, economical and very effective.A neglected pool will need a double-dose to start off, but this will effectively kill the algae and clear the water in a few days. Black algae will disappear over a few weeks and should be brushed off the walls.
