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

Manual- vs automated data collection

On many fish farms, several water quality parameters (including toxic free CO2) are only measured manually at fixed times or in selected tanks. The water quality is fluctuating daily and are often following rhythmic patterns. With this method, you will often miss the peaks and therefore create a misleading result of a satisfying, stable CO2-level. This white paper compares and analyzes two identical data sets presented in two different ways. Read more
