Effective, natural control of toxic Hydrogen Sulfide

PondDtox® contains unique bacteria (Paracoccus pantotrophus), which are highly effective in anaerobic conversion of toxic H2S into non-toxic sulfate in benthic environments. PondDtox® will sink to the pond’s bottom, and readily convert H2S back to sulfate again, while inhibiting the sulfate reducers. This ultimately mitigates the toxic environment ensuring maximum pond productivity.

Hydrogen sulfide (H2S) is a common, but toxic, metabolite formed in aquaculture ponds. Aerobic bacteria colonizing a pond’s sediment layer break down excess feed and accumulated organic waste. This results in anaerobic zones where sulfate-reducing bacteria thrive. This can quickly lead to the build up of toxic levels of H2S in the benthic environment.

In a recent field study, PondDtox® treated ponds yielded 293.9lbs per acre more at harvest compared to untreated ponds — an increase of 56.4%.

Signs of Hydrogen Sulfide Toxicity

By the time farmers notice the tell tale black sludge and ‘rotten egg’ smell of H2S, the impact on productivity will already be occurring.

Continued exposure to H2S in ponds causes reduced productivity in the form of increased mortality, reduced growth, and decreased feed conversion efficiency.
