Description
Pool Blocks are copper sulphate based algaecide pucks that are non-foaming, and kill green, mustard and black algae that grows on the walls and on the floor of swimming pools. Initially, add 1 Pool Block puck per 25,000 L of pool water in the skimmer basket. A monthly dosage of 1 puck per 50,000 L is recommended for persistent algae growth. Adjust pool water pH and maintain between 7.2 – 7.6 during treatment. Brush walls weekly when treating black spot algae.
Pool Blocks are not a sanitizer and must be used in conjunction with a sanitizer. Copper Sulphate products should always be accompanied by a sequestrating agent to prevent staining and scaling.
