Tropic Marin SYN-BIOTIC Meersalz/Sea Salt - 25 kg Eimer/bucket

SYN-BIOTIC Sea Salt - Pharmaceutically pure sea salt with probiotic bacteria and prebiotic bacteria food

Product description

The new Tropic Marin® Syn-Biotic Sea Salt contains probiotic bacteria for fish and shrimp and special prebiotic bacteria food to promote probiotic bacterial growth and to create low-nutrient conditions in the aquarium for LPS and SPS corals. The term synbiotic refers to supplements which combine probiotics and prebiotics in a form of synergism.  

Tropic Marin® Syn-Biotic Sea Salt is ideal when you are setting up a new tank and every time you expand the tank’s stock. It has been proven that probiotic bacteria help to overcome stress and disease while enhancing the health and well-being of fish and crustaceans. For the best results, the aquarium should have a water change with Syn-Biotic Sea Salt prior to any new stock being introduced.  

The contained prebiotic additives promote the integration of nitrates and phosphates in bacterial mass for low-nutrient conditions and the vivid colours of LPS and SPS corals. For a sustained acclimatization of animals to the aquarium conditions and to stabilize the microbiology of the tank system we recommend using Syn-Biotic Sea Salt permanently. Each water change with Syn-Biotic Sea Salt automatically adds the probiotic bacteria necessary to maintain healthy biological processes.


  • It has been proven that probiotic bacteria improve the health and well-being of fish and crustaceans and assist them in overcoming stressful situations and illness
  • Prebiotic additives promote the integration of nitrates and phosphates in bacterial mass for low-nutrient conditions and the vivid colours of LPS and SPS corals
  • Contains additional nitrifying and de-nitrifying bacteria to support the nitrogen cycle
  • Ideal for a new tank installation, a new stocking process and for every livestock increase
  • Suitable for permanent use - for a stable microbiology within the aquarium
  • Dissolves in water quickly and completely
  • Produced with pharmaceutically pure salts, without any nitrate or phosphate additives or other unnatural enrichments
  • Universally applicable - suitable for keeping and breeding fish, corals and other invertebrates, as well as seaweed

Application and dosage

To achieve a salinity level of 32 - 35 ‰ (psu), dissolve 35 ml (approx. 37-40 g/1.3-1.4 oz.) of Tropic Marin® Syn-Biotic for every litre or one half cup for every US-gallon of water in a container, stirring continuously. The specific gravity of the sea salt solution should be 1.025 to 1.027 at a temperature of 25 °C/77 °F. The prepared saltwater can be used as soon as the salt is fully dissolved.  

Note: Always add the sea salt to the water - not the other way round. When checking the conductivity of freshly prepared Syn-Biotic saltwater the conductometer will show ca. 10 % low results, because the contained organic substances affect the measurement. We recommend measuring the specific gravity with the Tropic Marin® Hydrometer.  

It is normal for the salt water to turn slightly cloudy and this indicates that the synbiotic additives are taking effect. After setting up a new aquarium it takes a few weeks of circulating and lighting to establish stable biological conditions for the care of delicate marine organisms. Changing up to 10 % of the water every week using Tropic Marin® Syn-Biotic helps to keep the water quality within the parameters most important to the delicate marine life in your aquarium.
