- Rapid sinking granules for targeted delivery to bottom-growing algae
- Visible reduction of algae growth 1-2 days
- Chelating agents prevent the precipitation of copper with carbonates and bicarbonates in the water for longer activity
- Stays active in the water longer than copper sulfate
- Ideal for algae in deeper waters or bottom growing algae – use Cutrine® Plus Algaecide (liquid) for algae on the surface or in the water column

How to Apply
A. Large area treatment, over 5,000 sq ft
- Identify the target growth: Chara, Nitella, bottom filamentous algae, or Hydrilla.
- Estimate plant height in feet, from bottom to top.
- Calculate the surface area of the treatment zone in acres.
- Use the table to find pounds of product per surface acre based on target and plant height.
- Distribute evenly over the water surface directly above the vegetation. A dry fertilizer spreader helps ensure even coverage.
Surface area formula
Surface acres = Length (ft) × Width (ft) ÷ 43,560
| Bottom filamentous | 1 ft height: 20 lb · 2 ft height: 40 lb · 3 ft height: 60 lb |
|---|---|
| Chara / Nitella | 1 ft height: 30 lb · 2 ft height: 60 lb · 3 ft height: 90 lb |
| Hydrilla | 1 ft height: 70 lb · 2 ft height: 140 lb · 3 ft height: 210 lb |
Rates are per surface acre based on plant height.
B. Spot treatment | under 5,000 sq ft
Apply 1.5 lb per 1,000 sq ft. If water is less than 1 ft deep, reduce by 2 oz per inch of water per 1,000 sq ft to avoid exceeding 1.0 ppm copper.

FAQs
Cutrine Plus Granular Algaecide FAQs
Answers to common questions about the Cutrine Plus Granular Algaecide.
What types of algae does Cutrine Plus Granular target?
It effectively controls bottom-growing benthic algae (e.g., Chara, Nitella, filamentous species) and even invasive Hydrilla—making it ideal for both sludge and rooted algae removal
How quickly will I see results?
Users typically observe visible reduction of algae within 24–48 hours, with full control achieved in about 7–10 days.
What makes the Cutrine Plus granular form different from the liquid form for bottom algae?
The granules sink rapidly, delivering copper directly to the algae, and chelating agents prevent it from binding with water hardness, ensuring prolonged efficacy.
Is Cutrine Plus Granular safe for my pond equipment and wildlife?
Yes—it’s less corrosive than copper sulfate and safe for fish and wildlife when used as directed. Avoid overapplication and treat in sections to prevent oxygen loss.
How often should I reapply during the season?
For continued control, a second treatment can be done after 14 days if necessary. In many cases, two to three applications per season suffice
What PPE is required when handling this product?
As will all algaecides, full protective gear is required to ensure the safety of the applicator—coveralls, gloves, eyewear, apron, and footwear—to avoid corrosive contact, especially during mixing.
