For larger lakes, the most efficient and cost-effective distribution method is to mix the Bio-Zyme bulk powder in a Bio-Generator. A Bio-Generator "brews up" the Bio-Zyme bulk powder, increasing the bacteria millions of times. The "brewed up" bacteria then is distributed directly from the generator into the lake. Also, the bacteria from the generator can be can off-loaded from the generator into any type of sprayer. Shoreline distribution is recommended.
