⚗️ Dosage & Treatment Instructions

Preparation:

• Use only in a quarantine or hospital tank. Copper is toxic to invertebrates, corals, and plants.

• Remove invertebrates and sensitive animals from the treatment tank.

• Turn off or remove chemical filtration (activated carbon, Purigen, etc.) and any UV or ozone devices.

• Maintain proper aeration and monitor water quality closely.

Dosage:

• Marine Tanks: 1 mL per 40 L (10.5 US gallons) for the first dose. Wait 48 hours, then repeat to maintain 0.5 mg/L copper throughout the 14-day treatment period.

• Freshwater Tanks: Use half the marine dose per 40 L (0.25 mg/L) for the 14-day period. Repeat dose at 48 hours if required.

Monitoring:

• Use a reliable copper test kit, such as the Salifert Copper Test Kit, to ensure therapeutic copper levels remain stable.

• Maintain consistent copper levels for the full 14-day treatment cycle to ensure parasites are completely eliminated.

After Treatment:

• Remove Cupramine using activated carbon or CupriSorb™.

• Perform partial water changes to ensure residual copper is removed before returning fish to the main display tank.

⚠️ Important Warnings

• Display Tank Use: Copper must never be used in a display tank containing corals, invertebrates, or live plants.

• Toxicity: Copper is lethal to shrimp, snails, corals, and many beneficial invertebrates.

• Contamination Risk: Porous decor, rocks, and substrate may retain copper residues — always treat in a separate hospital tank.

• Monitoring is Critical: Accurate measurement with a copper test kit is essential to avoid overdosing or ineffective treatment.

🌿 Aquarist Insight

Copper is one of the most effective treatments for external parasites, but precision is key. Underdosing may allow parasites to survive, while overdosing can seriously harm or kill fish. Cupramine provides stability and predictability, allowing hobbyists to safely administer copper with confidence.

Paired with a Salifert Copper Test Kit, aquarists can track copper levels accurately, ensuring the treatment is both effective and safe. By carefully monitoring and maintaining therapeutic copper levels, fish recover faster and with less stress.
