Product information

Description

The sera Calcium-Test (Ca) is a water test reagent for measuring calcium concentration in freshwater and marine aquaria, ponds and other controlled water systems. Supplied in a 0.015 L hanging box and manufactured in Germany, the reagent enables stepwise measurement of calcium in increments of 20 mg/l (ppm). The test kit provides enough reagent to determine approximately 7,500 mg (ppm) of calcium in total and is intended for routine monitoring to help maintain stable water chemistry for aquatic life.

Advantages

The test delivers clear, repeatable results in defined steps of 20 mg/l, allowing users to track changes in calcium concentration over time. Its compact 0.015 L format is convenient for storage and use in both hobby and professional settings. Made in Germany, the reagent follows established production standards for analytical reagents and is compatible with common aquarium maintenance routines.

Suitable for

  • Monitoring calcium levels in marine and reef aquaria
  • Checking calcium concentration in freshwater aquaria and garden ponds
  • Routine water quality control for aquaculture or breeding setups
  • Complementary testing alongside alkalinity and magnesium measurements

Key specifications

  • Measured parameter: Calcium (Ca)
  • Measurement resolution: 20 mg/l (ppm) steps
  • Reagent volume: 0.015 L (15 ml)
  • Origin: Germany
  • Approximate total measurable amount: covers up to 7,500 mg (ppm) of calcium readings

How to use

Collect the required water sample according to standard aquarium testing practice. Add the reagent drops or volume as specified in the included instructions and observe the colour change or end point used for the sera Calcium-Test (Ca). Compare the result to the supplied colour chart or follow the stepwise counting method to determine calcium concentration in 20 mg/l increments. If results are outside target ranges, follow corrective procedures such as adding a calcium supplement or performing partial water changes.

Usage recommendations

Use the test regularly as part of a water quality monitoring routine. For low calcium readings, dose a suitable calcium supplement such as sera marin COMPONENT 1 Ca according to product instructions. For elevated calcium levels, perform partial water changes to reduce concentration gradually. Store the reagent in a cool, dry place away from direct sunlight and follow safety and disposal guidance on the packaging.
