Abstract

A method of treating water includes introducing a chemical dispenser (10) containing a water treatment substance (36, 38) , into a body of water so that the dispenser (10) is located at a first level in the water. Water enters the dispenser through an aperture with the water coming into contact with the water treatment substance, and an active ingredient thus being released into the water. Active ingredient is thereby dispersed into the body of water at the first level . The dispensing of active ingredient into the body of water at the first level is continued for a period of time. Thereafter, the dispenser is allowed to rise to a second higher level in the body of water. For a further period of time, active ingredient is dispensed from the dispenser int the body of water at the second level .
