Often manufacturers of marine aquarium supplements make things simple by premixing the various Calcium, Carbonate and Magnesium solutions with certain trace elements. From our experience it is better to have full control over these essential additional elements. Our Coral Essentials Method provides your marine aquarium corals the minerals and vitamin supplements they require for healthy growth, vivid colouration and vitality. Our product additives cover all aspects of marine aquarium supplementation and management. From trace elements, to feeding, and our exciting new range of Black Label products.
