pH in Aquaculture, Agriculture, & Hydroponics
In order to ensure the health of aquaculture and agriculture environments, pH measurement needs to be accurate and concise. The quality of the biological environment is dependent upon optimal pH levels. Even the smallest of deviations can cause stress and illness.
In fish farming facilities, open sea fish farms and even aquariums, pH changes may be the first indication of nitrogen cycle (ammonia) problems and are easy to monitor on a continuous basis. Low-levels of pH can lead to the accumulation of toxic ammonia, where as high levels can cause breakdown of fish gills leading to respiratory failure. Even the smallest of contaminants in commercial and residential aquariums can be deadly to expensive fish and plants.
