Water pH affects nutrient availability, photosynthesis, and overall culture health -- all essential factors in algae farming. Algae typically grow best within a pH range suited to their species, with many thriving between 7 and 9. Regular monitoring using pH meters allows farmers to track changes and respond quickly.
Carbon dioxide injection is a common method to lower pH, as CO2 dissolves in water and forms carbonic acid. To raise pH, farmers can add small amounts of alkaline substances like sodium bicarbonate or calcium carbonate. Maintaining stable pH helps prevent stress, promotes efficient nutrient uptake, and reduces the risk of contamination by unwanted organisms that thrive under extreme pH conditions.
