Overview
Copper-based medications are one of the most effective tools for treating common parasites in quarantine, but the margin between an effective therapeutic dose and a toxic one is genuinely narrow. Colour-matching test kits just don't have the resolution to dose confidently in that range. The Copper Low Range Checker from Hanna replaces guesswork with a precise digital reading, giving you an accurate ppb-level copper result at the push of a button.
It's built specifically for the low end of the copper scale, which is exactly where careful QT dosing needs to sit.
Key features
- Digital colorimeter — no more squinting at colour charts to estimate a result
- Measures in the low range (0 to 999 ppb), matched to therapeutic copper treatment levels
- Simple one-button operation for fast, repeatable readings
- Uses the bicinchoninate method, an adaptation of the EPA-approved copper testing method
- Compact and portable, easy to keep alongside your quarantine gear
Who it's for
Essential for anyone running copper treatment in a quarantine or hospital tank, where knowing your exact copper level — not just an approximate range — genuinely matters for both treatment efficacy and fish safety.
Setup & tips
- Zero the checker with a blank sample before each test to keep readings accurate
- Test regularly during treatment, since copper levels can drop as it's absorbed by tank surfaces or bound up in the water
- Use fresh reagents and check expiry dates, as degraded reagents will throw off your results
- Keep this as a dedicated QT tool — copper has no place in a display reef tank
