PoolFresh Plus should be used in conjunction with the PoolFresh units and added approx once every 8-12 days in summer & once per month in winter.
When added to the water, active oxygen is produced which combines with the trace elements and elevates them into highly effective bactericides and algaecides. When added to the pool water, PoolFresh Plus is completely tastless & odourless. It remains in the water as a long lasting residual whose presence can be confirmed by simply using a normal DPD chlorine test kit.
