Hydrogen Sulfide – The silent killer
Elevated levels of hydrogen sulfide (H2S) have lethal effects on fish. The presence of oxygen will work against the production of H2S, but it is a very slow process that cannot protect the fish in situations with sudden spikes of H2S. These anaerobic environments with H2S can form anywhere on a fish farm, particularly in biofilters and stagnant piping systems. Read more
