JBL Oxygen Test O₂
Oxygen test

  • Recommended oxygen content: 8 mg/at 25° C.
  • Test providing accurate readings of oxygen levels from 1-10 mg/l in freshwater and marine tanks as well as garden ponds.
  • Important when algae-removal preparations are used, as large amounts of oxygen are used when algae are eliminated.
  • Recommended for use at night in densely planted aquariums, when large amounts of O₂ are absorbed.
