Radiance is the first algaecide that can give you preventative
control of algae blooms in ponds, lakes and fountains. The active
ingredient in Radiance is a biologically active form of copper
held in a proprietary carrier. Radiance self-disperses from a single
application point and remains suspended in the water column. The
unique properties of this carrier let Radiance maintain effective
concentrations of biologically active copper in suspension throughout
the body of water being treated.
Radiance is the only self-dispersing algaecide on the market that
prevents algae and protects against reinfestation for up to a full
month. Because it requires no special equipment or application practices,
having clean lakes all summer long is quick and easy.
