calcium and light

Coralline algae is classed as a red algae. Red algae is unique because it has adapted to be able to photosynthesise not only in light (producing O2) but also in darkness and at night (producing CO2). This means that coralline algae can still thrive in low light, as long as the water has a high enough oxygen content.
