Seachem Cupramine 250 ml

Remove all invertebrates before treatment — they are extremely sensitive to copper. Turn off UV/ozone and remove chemical filtration; avoid conditioners or ammonia binders containing reducing agents while treating.

• Dosage: If the bottle has a dropper cap, use 20 drops (1 mL) per 40 L (10.5 US gallons) on the first day, wait 48 hours, then repeat.
• Target Concentration: Final copper concentration should be 0.5 mg/L (0.25 mg/L in freshwater), maintained for 14 days.
