Cutrine-Plus Liquid Algaecide by APPLIED BIOCHEMISTS — EPA-Approved Copper Formula for Ponds & Lakes

Overview

APPLIED BIOCHEMISTS Cutrine-Plus Liquid Algaecide is a professional-grade copper-based solution designed to address common algae in ponds, lakes, hatcheries, and irrigation systems. It aims to improve water clarity by targeting the main algae groups that thrive in aquatic environments.

Key benefits

• Targets all major algae types: planktonic, filamentous, and chara for comprehensive control.
• Fast-acting results: users may see reductions in algae growth within 1–2 days.
• No restrictions on fishing, swimming, drinking, or irrigation when used as directed; designed to be safe for wildlife and livestock.
• Simple spray application for both large-scale coverage and spot treatments.
• EPA-approved copper-based formula with compliance considerations; note shipping restrictions in certain regions.

Real-life expectations

In ponds and lakes, many users report visible improvements in water clarity within a few days, especially when hotspots are treated. The product’s copper-based chemistry is formulated to work where algae tend to accumulate, contributing to a clearer, more balanced water profile without assuming permanent solutions.

How to apply

Apply directly to targeted areas using a sprayer. For larger water bodies, distribute across zones with higher algae density to maximize contact. Always follow the label directions and avoid using in waterbodies with copper-sensitive fish. The spray-ready format supports both broad applications and precise spot treatments.
