The Hanna Instruments Copper High Range Reagent provides 25 individual tests for use with the HI702 Copper High Range Checker HC. These replacement reagents are essential for accurately measuring therapeutic copper levels in saltwater aquariums, a critical step when treating fish for common parasites like marine Ich (Cryptocaryon irritans) and Velvet (Amyloodinium ocellatum). By providing precise digital readouts, these reagents help aquarists maintain effective copper concentrations for treatment.

This reagent set is manufactured with high-purity chemicals and comes in pre-measured packets, ensuring ease of use and consistent, lab-quality results every time. The colorimetric method employed by the Hanna Checker system eliminates the subjectivity and guesswork associated with traditional color-matching test kits. Each packet is clearly marked with an expiration date and lot number for traceability, guaranteeing the reliability and accuracy that Hanna Instruments is known for in the aquarium hobby.

This product is indispensable for saltwater aquarists who are running a quarantine system or treating a hospital tank with copper-based medications. Maintaining a stable therapeutic copper level is vital, as levels that are too low will be ineffective, while levels that are too high can be toxic to fish. These reagents provide the peace of mind that comes from knowing the exact copper concentration, allowing for precise dosing and ensuring the health and safety of your marine livestock during treatment.
