## Long description

sera Sól morska reef salt is a 20 kg bag of marine aquarium salt formulated to prepare synthetic seawater for reef and marine systems. Designed to reproduce the basic salinity and mineral balance required in marine and reef aquaria, this salt mix is suitable for creating water for both reef tanks and fish-only setups. The product supplies the primary dissolved salts and trace elements that establish the standard ionic composition needed before further adjustments for specific reef livestock.
Advantages
The salt mix provides a consistent baseline salinity and mineral content when dissolved according to instructions, enabling stable water chemistry for routine water changes and tank setup. Its bulk 20 kg packaging is suitable for larger aquaria or frequent maintenance schedules, reducing the need for frequent repurchasing. The formulation is intended to be compatible with common reef testing and dosing routines, supporting predictable adjustments for calcium, alkalinity, and magnesium using dedicated supplements.

Packaging: resealable/integrity packaging designed for storage and repeated use
How to use
Dissolve the specified amount of sera Sól morska reef salt in freshwater at the temperature recommended for your aquarium until fully dissolved and clear. Measure salinity or specific gravity with a calibrated refractometer or hydrometer and adjust concentration to the target value for your system. Allow the mixed seawater to equilibrate to the aquarium temperature before adding it to the tank. When using for reef aquaria, test key parameters such as calcium, alkalinity and magnesium and dose additional supplements as required to reach desired levels for corals and invertebrates.
Usage recommendations
Store the product in a cool, dry place and seal the bag after each use to prevent moisture uptake. Prepare water in quantities that will be used within a reasonable time frame and always verify salinity and temperature prior to dosing into the aquarium.
