sera 04002 water testing product

sera Aqua-test box (+ Cu) is a compact chemical test set for aquarium and pond water designed to measure multiple water quality parameters including copper (Cu). The kit enables on-site assessment of copper concentration alongside other common indicators, helping hobbyists and aquarists detect potentially harmful levels and track general water condition for fish and plants.

Advantages

The test set combines copper measurement with other routine water checks in a single portable box, offering clear colorimetric results that are easy to read without specialised equipment. The reagents and test tubes are arranged for straightforward operation and rapid results, allowing frequent checks and early detection of changes in water chemistry. The compact format makes storage and transport practical for use at home or at outdoor ponds.

Suitable for

• Freshwater and outdoor pond hobbyists monitoring copper and general water quality
• Aquarists checking water safety for sensitive fish and invertebrates
• Routine maintenance checks after medication, water changes, or source water testing

Key specifications

• Includes chemical reagents for copper (Cu) measurement and additional routine parameters
• Colorimetric tests providing visual readout via comparison scale
• Compact, portable plastic case with dedicated reagent vials and test tubes
• Designed for multiple test runs; reagent volume supports repeated measurements
• Suitable for freshwater aquaria and garden ponds

How to use

Collect a sample of aquarium or pond water following the instructions supplied in the kit. Add specified drops of reagent to the provided test tube, mix as directed and wait the recommended reaction time. Compare the resulting color against the kit’s color chart to determine the copper concentration and other parameter values. Dispose of used reagents responsibly and rinse test tubes after each use to avoid cross-contamination.

Usage recommendations

Perform tests at consistent times and locations within the aquarium or pond to obtain comparable results. Use the copper measurement when assessing effects of medication, fertilizer treatments or accidental contamination, and repeat tests as needed to monitor trends. Store reagents in a cool, dry place away from direct sunlight and follow safety instructions on the packaging.
