Fritz Mardel Coppersafe® is a safe, stable, and non-staining chelated copper concentrate designed to deliver rapid, effective relief from unwelcome external parasites. It is highly effective for treating and controlling freshwater and saltwater Ich, Velvet, flukes, anchor worms, and other external protozoan diseases. Unlike standard free copper treatments that require daily monitoring and redosing, Coppersafe's unique chelated formula remains active and therapeutically stable at 1.5 ppm to 2.0 ppm for up to one full month with just a single dose. It does not discolor your aquarium water or interfere with biological filtration when used as directed, making it the industry-standard choice for quarantine systems and main fish-only displays.
Key benefits
Long-Lasting Formula: A single dose maintains therapeutic copper levels of 1.5–2.0 ppm for up to one month, eliminating the need for daily redosing.
Broad-Spectrum Control: Effectively targets and treats Ich, Velvet, flukes, anchor worms, and other troublesome external parasites.
Non-Staining Concentrate: Specially formulated to stay fully dissolved in the water column without discoloring your water or staining aquarium seals and equipment.
No Filter Disruption: Safe for use without turning off or removing biological filtration media.
Dual System Safe: Formulated to work equally well in both freshwater and saltwater fish-only setups.
Specifications
Net volume: 16 oz (473 ml)
Form: Chelated copper liquid concentrate
Primary purpose: Treatment of Ich, Velvet, flukes, and external parasites
Water type: Freshwater and Saltwater (Fish-only; not reef safe)
Intended users: Aquarium hobbyists, quarantine coordinators, and professional aquarists
Suggested use
Dosage Rate: Use 5 ml (1 teaspoon) per 4 U.S. gallons (15 liters) of water, or 1 cup (8 oz) per 190 U.S. gallons (337.5 liters). This initial dose establishes a therapeutic level of ~2.0 ppm.
Water Changes: When performing water changes during treatment, always add a proportional dose of Coppersafe to the replacement water to keep therapeutic levels steady.
Removal: Because of its high stability, performing partial water changes is the most effective way to remove Coppersafe from your aquarium.
Equipment adjustment: Discontinue use of protein skimmers, UV sterilizers, and heavy-metal-adsorbing filter media (like Cuprisorb) during treatment. Carbon filtration does not need to be removed.
Ingredients Active ingredient: Chelated Copper Sulfate.
Guaranteed Analysis
Active Copper Level: Consistently maintains 1.5 ppm to 2.0 ppm total copper when dosed correctly.
Storage and safety
Store in a cool, dry place away from direct sunlight.
Keep the container tightly sealed when not in use.
Keep out of reach of children and household pets.
Warnings
Not reef-safe: Do not use in systems containing live corals, anemones, snails, shrimp, crabs, or any other invertebrates.
Do not use in aquariums containing scale-less fish unless at a reduced dose or monitored closely.
For aquarium use only. Not for human consumption.
