In 1997, a case study for using PAK™27 was performed at the Bill Evers Reservoir in Bradenton, Florida. Bill Evers Reservoir, which is fed by the Braden River, has a surface area of 330 acres and a capacity of 1.5 billion gallons of water. The results of this study revealed that as little as 6.5 pounds per acre-foot is effective as an algaestat for cyanobacteria species like Anabaena and Planktothrix (Oscillatoria).

The City of Bradenton has been successfully controlling cyanobacterial blooms with PAK™27 since 1998. In Bradenton, the “bloom” season can start as early as February and continue until late fall. PAK™27 is the ideal, environmentally sound, cost effective cyanobacteria algaecide. It is:

1. Selective for cyanobacteria at recommended application rates
2. Nontoxic to the ecosystem
3. Not bio-accumulative
