JBL Oxygen Test O

JBL Oxygen Test O₂

• 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.
