Following in the footsteps of the acclaimed Cukote Self-Polishing Antifouling, Cukote Biocide Plus (adapting newer technology) has a high cuprous oxide content, combined with an organic algaecide - offering unprecedented control over all types of fouling, even in the most severe fouling areas. Cukote Biocide Plus' unique controlled erosion minimizes coating buildup and keeps underwater surfaces smooth and clean.
