Hanna Instruments Marine pH Handheld Checker HC (Colorimeter)

pH of ocean surface water is normally 7.5.to 8.5 pH.
Over the years however, acidification tendency is to decrease 0.1 to 0.2 pH units/century. Acidification is a consequence of carbon dioxide (CO₂) absorption in seawaters and oceans. Carbon dioxide reacts with seawater to produce carbonic acid (H₂CO₃).
pH modifications affect marine life growth, reproduction, and communication. Hydrogen ions have a tendency to bond with carbonate to form bicarbonate. The greater attraction to carbonate over calcium can adversely affect skeleton building and can limit coral growth.
