Algaecide tablets 2X 300 gram blocks 

Non-foaming solid algicide kills green, mustard algae and black algae growing on the walls of swimming pools.  It is not affected by sunlight and keeps water sparkling clear.

Directions for use:  Initial dose, place one Pool block per 25,000 litres of water in the weir skimmer basket when the pump is running.  If algae persists, a monthly maintenance dosage of one Pool Block per 50,000 litres or half (1/2) per 25,000 litres is recommended.  Adjust pH to 7.2 -7.6.  Use in conjunction with chlorine or other sanitizer.
