Cutrine Granular Algaecide - 30 lb. bag

Cutrine Plus Granular Algaecide is fast acting and works great on bottom-growing algae (Chara). Easy-to-use granules (same active ingredient as the liquid version) settle on the algae and immediately begin attacking algae growth. For best results, apply this granular algae treatment early in the morning before heavy mats form, on a sunny, calm day. Contact time should be a minimum of 3 hours. For large treatment areas, treat 30 lb per 1/2 acre. Each bag is vacuumed sealed for shipment.
