TM Pro-Reef salt 25KG

Tropic Marin® PRO-REEF sea salt has been designed to meet the special requirements of reef aquariums with optimized concentrations of calcium and magnesium, which promote the growth of corals. The lower buffering and the correct pH value serve to stabilize the natural water values, and particularly, the hardness of carbonates, even with the use of calcium reactors. Natural and stable conditions for delicate marine life are achieved only by accurately balancing all influencing factors. With Tropic Marin® PRO-REEF you can maintain the alkalinity in a 7-8° dKH range.
 
Benefits
• Designed to meet the special requirements of modern reef aquaria with higher calcium requirements.  
• Optimizes calcium- and magnesium concentrations as well as alkalinity and pH.
• Especially suitable by the use of calcium reactors or mineral additives.
• To maintain the alkalinity in a 7-8° dKH range.
• Fast and complete solubility in water.
• Free from nitrates, phosphates and other unwanted chemicals.
• Manufactured from pure, pharmaceutical grade salts.
• Ideal foundation for the care and growth of fish, corals and other aquatic invertebrates in modern reef aquariums.

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® PRO-REEF per litre or approximately ½ cup of Tropic Marin® PRO-REEF per US gallon water. Dissolve almost all of the salt in a clean container already filled with the full volume of RO/DI water at a temperature of 73-77°F / 23-25°C while circulating/stirring the water. Do not concentrate the mixture by adding the full amount of salt to a smaller amount of water. 
Note: Always add the salt to the water, never the water to the salt.  Making a concentrated mixture will cause a calcium carbonate precipitate to form. 
When you have added ALMOST all of the salt and the mixture is fully dissolved and clear, start measuring the specific gravity with a hydrometer or similar instrument. Keep adding small amounts of salt until the specific gravity is the value you desire. The specific gravity of the sea salt solution should range from 1.025 to 1.027 (at 73-77°F / 23-25°C) and the pH-value should be in the range of 8.0 – 8.4. If all parameters are correct, the salt water is ready to use. 
After setting up a new aquarium it takes a few weeks of water being circulated and correct lighting conditions to achieve the biologically stable environment required for the care and breeding of delicate marine organisms. 
A weekly, partial water change, replacing 10 % of the total water volume with Tropic Marin® PRO-REEF, will help to maintain the water quality that your livestock needs for good health.
