Product Overview
Cutrine® Ultra Algaecide is a fast-acting, liquid copper-based algaecide formulated for effective algae control in ponds, lakes, reservoirs, and other freshwater systems. Designed for professional aquatic management, Cutrine Ultra targets a broad range of nuisance algae, including planktonic (free-floating), filamentous, and certain benthic species.
The liquid formulation disperses quickly throughout the water column, allowing for uniform coverage and rapid contact with algae. This makes Cutrine Ultra an ideal solution for spot treatments, surface applications, or whole-pond algae treatment where even distribution and quick results are desired.
Cutrine Ultra is commonly used in pond and lake management programs and is most effective when applied early in the growing season or at the first sign of algae growth. When used according to label directions, it helps manage algae populations while supporting balanced aquatic conditions.
