The biocide is designed to reduce fish pathogens in the water and, according to Evonik, can be applied while fish are present, as it breaks down into only water, oxygen, and acetic acid. The company says that it has no-observable effect on salmon and similar fin fish in concentrations below 3.5 mg/L.

“Evonik has been pioneering this new technology in close collaboration with authorities and research facilities. We are very pleased to be able to offer our customers an effective treatment to reduce waterborne fish pathogens that can be used with fish present,” Philip Block, technology director for specialty markets at Evonik Active Oxygens in North America, said in a press release. “Keeping water clean is an important first step in pathogen management — which is a big concern to operators of RAS systems.”

“We work closely with regulators to ensure that our products are effective when used as directed,” said LuAnn Maloney, regulatory manager for Evonik Active Oxygens in North America. “The new EPA registration for Vigorox Trident attests to our commitment to offering our customers effective solutions that help them meet compliance standards.”
