Aqua Medic Reef Salt is a blend of natural essential trace elements, Strontium and Iodine. This is vital for a healthy reef aquarium. Corals and other life forms take these elements from the water to build healthy formations and thrive.
It doesn't contain any phosphates or nitrites, so it won't contribute towards any algae growth. It also dissolves easily - leaving no residue.
Simply follow the instructions for correct use.
