The HI-3823 provides users with the most important test parameters for aquaculture applications: alkalinity, carbon dioxide, dissolved oxygen, hardness, pH and salinity.
Each of these parameters plays a critical role in the delicate balance of the aquatic environment: alkalinity acts as a stabiliser for pH; carbon dioxide must be monitored because of its toxic effects on fish (every species can tolerate different levels of CO2); oxygen levels affect fish respiration and incorrect concentrations can slow down their growth rate; hardness is monitored because it diminishes the toxicity level of ammonia; pH also is measured to determine the toxicity level of the water; salinity is important because of its relation to dissolved oxygen.
