Tropic Marin offers a comprehensive range of sea salt products for different marine aquarium applications, with formulations designed to support water stability, coral health, and reef system performance.
PRO-REEF is formulated with elevated calcium and magnesium levels to support the growth of stony corals and help maintain stable pH conditions. It is particularly suitable for reef aquarium systems.
BIO-ACTIF contains natural biopolymers and probiotic components designed to enhance biological resilience and optimize microbial balance in marine aquariums.
The classic sea salt formulation contains around 70 trace elements found in natural seawater and is produced with pharmaceutical-grade purity. It is designed to provide reliable seawater preparation without unwanted nitrate or phosphate residues.
Tropic Marin sea salts are validated for high solubility and are formulated to achieve a specific gravity closely matching natural seawater after mixing, typically in the range of 1.024–1.026.
Tropic Marin also provides a range of supplements and care products for reef maintenance, coral nutrition, and water quality management.
TRACE-TRACE B is a trace element supplement designed to support coral coloration and overall coral health.
The NP-BACTO series includes products such as Balance and Tricks, which use probiotic-based approaches to help reduce nitrate and phosphate levels and maintain water quality.
The PRO-CORAL line includes specialized reef care products such as BIO-CALCIUM for calcium supplementation, IODINE for iodine replenishment, and ZOOTON/PHYTON for plankton-based coral nutrition.
