Couldn't load pickup availability
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. For a 25,000L pool, one puck will go into the skimmer basket, if algae persists then a monthly dose is recommended. Copper Sulphate products should always be accompanied by a sequestrating agent to prevent staining and scaling.

Love this product. Better than putting in liquid. I put one in with the chlorine pucks, and the pool is clear for a month.
