Provide your reef aquarium with essential calcium using Sera Marin Component 1 Ca 250ml — a concentrated calcium supplement specially developed to support healthy coral growth, strong skeletal development, and stable marine water chemistry.
Calcium is one of the most important minerals in reef aquariums. Hard corals (SPS and LPS), calcareous algae, clams, and many marine invertebrates continuously consume calcium to build and maintain their skeletons and shells. Regular supplementation helps prevent calcium deficiencies and promotes healthy growth and vibrant reef development.
Sera Marin Component 1 Ca is designed to be used together with Sera Marin Component 2 Ca pH-Buffer, ensuring balanced calcium supplementation while maintaining stable pH and carbonate hardness. It is part of the complete Sera Marin Component 1–7 System, providing essential nutrients for demanding marine aquariums.
