How high is the TGP in your water?

Total gas pressure, TGP, is the sum of the partial pressures of all gases dissolved in water plus the water vapor pressure. When water is supersaturated, it may cause gas bubble disease in fish and other aquatic animals. The reasons why water becomes supersaturated are:

  • Heating of water
  • Air leaks or air entrainment on the suction side of pumps
  • Water brought up from deep wells
  • Entrainment of air in water released over dam sluice ways

TGP should be monitored or spot checked with a handheld meter, like InWater Technologies’ new TGP Tracker. For info email info@inwatertech.com.
