A guide to Good Water Quality management
Blue Unit’s business purpose is to generate and transform enormous amount of important, raw data collection on the fish farm into meaningful and useful information, and to cooperate with farm management in order to improve fish farm performance.
Fish and bacteria produce CO2 into the production water of RAS farms, it is therefore essential that a farm has complete control on the degassing efficiency of their system.
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.
