The JBL ProAqua O2 test set is a means of exactly determining and routinely controlling the oxygen content in fresh water and marine tanks, tap water and ponds within a range of 1 - 10 mg/l (ppm).

• 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
• Includes syringe for simple measurement of the amount of water
