Rely on concentrated Halt® 50 Algaecide to kill and prevent all types of algae. A single quart of this super concentrated swimming pool algaecide treats up to 240,000 gallons — a great value! Plus, this non-metallic, low-foaming formula will not stain or discolor hair. Swim immediately after treatment. Great for all pool types. Maintenance dosage: 1-1/3 oz. per 10,000 gallons.
Algae growth is common when your pool has poor circulation and when the disinfectant level, or algaecide content in the water is low or neglected. Proper filtration (we recommend running filter at least 8-10 hours a day) and regular use of Blue Wave® algaecide will keep your pool free of algae.
Halt 50 is available in a 32 oz (quart) size.
