## Summary description

sera Mineral salt (SE-03403) is a 2.5 kg mineral salt for aquarium water treatment. It supplies essential minerals and electrolytes to maintain water chemistry and support fish and invertebrate health. Suitable for freshwater aquaria where mineral supplementation or water remineralization is required after purification or soft water top-ups.

## Long description

sera Mineral salt is a 2.5 kg mineral supplement formulated for freshwater aquaria to restore and maintain balanced water chemistry. It supplies essential minerals and electrolytes that contribute to stable parameters, support physiological functions of fish and invertebrates, and help prevent deficiencies after water changes, purification, or when topping up soft water.
Advantages
This mineral salt provides a controlled blend of minerals and electrolytes tailored for aquarium use, enabling consistent remineralization without altering water clarity. It supports osmoregulation and general health in freshwater species, is easy to dose, and can be used alongside common filtration and conditioning routines. The granular formulation dissolves readily to deliver predictable changes in water hardness and mineral content.
Suitable for
 Freshwater community aquaria requiring mineral supplementation
 Aquariums after reverse osmosis, deionized or distilled water additions
 Soft-water biotopes needing controlled increase of general hardness (GH)
 Routine water changes to replenish essential ions and electrolytes
Key specifications
 Net weight: 2.5 kg
 Formulation: mineral salt blend supplying essential electrolytes and minerals
 Intended use: remineralization and mineral supplementation of freshwater aquarium water
 Solubility: readily water-soluble granular powder
 Compatibility: suitable for use with common aquarium filtration and conditioning products
How to use
Dissolve the required amount of mineral salt in a separate container of aquarium water before adding to the tank to ensure even distribution. Adjust dosing according to the desired change in water hardness and the volume of water treated; small incremental additions with parameter testing are recommended when establishing target GH and mineral levels. Use after large water changes, when topping up with purified or very soft water, or periodically to maintain stable mineral content. Always follow local water parameter testing to confirm dosing effects.
Usage recommendations
Measure aquarium water parameters (GH, KH, pH) before and after dosing. Make gradual adjustments rather than large single additions, particularly in sensitive or mixed-species setups. Store the product in a dry, cool place and keep the container tightly closed to prevent moisture uptake.
