Sustain Winter Shield

Algae knows no season.  They can develop during the winter months and early spring only to be discovered when you remove the pool cover. Protect against algae by applying Sustain Winter Shield at the end of the swimming season as part of your shutdown procedure.

During shutdown, Winter Shield absorbs excess chlorine from the shocking routine and holds it in suspension as a back-up reserve guard against algae development.
