Black Out 1.5L

Black Out 1.5L is a highly concentrated algaecide for treatment against stubborn algae. "Blackspot" algae appear when a pool has been neglected i.e. inefficient filtration and circulation, pH testing and/or chlorine levels have not been maintained regularly.

Dosage and Directions for use:
Use 250ml per 10 000L of pool water.
Pour the contents of this bottle into the pool at the inlet where the water jets into the pool.
Do not allow swimming for 30 minutes after addition.
Backwashing is necessary to avoid a build-up of dead algae in the filter sand. Brush after treating to remove dead algae from pool walls and floors.
