Coralline Algae

Coralline Algae can take anywhere from a week to a year to start growing in a new saltwater aquarium. Coralline Algae can grow in colors ranging from shades of light pink to dark purple and will cover any hard surface in your aquarium over time. The Coralline is a great defense against nuisance algae and other unwanted growth on your rock and once coralline can start growing, that is a great sign that you can also sustain coral in your saltwater aquarium as well.
