Purple Encrusting Coralline Algae

Purple Encrusting Coralline Algae is a desirable encrusting algae that naturally develops on rock surfaces in established marine aquariums. Known for its deep purple to pink coloration, it creates the classic “mature reef” appearance while helping stabilize surfaces within the aquarium.

This offering provides live coralline-coated rock fragments designed to seed and accelerate coralline growth throughout your tank. Under proper conditions, coralline algae can gradually spread across rockwork, transforming sterile surfaces into a natural reef environment.

Available Sizes

1-2" Encrusting Live Rock

Small piece of rock with visible purple coralline coverage

Ideal for introducing and seeding coralline algae into newer systems

Best for hobbyists looking to begin natural spread over time

3-4" Encrusting Live Rock Colony

Larger rock piece with heavier purple coralline coverage

Provides stronger immediate visual impact and more seeding surface

Ideal for established reef systems wanting a fuller mature-reef look faster

Special Considerations

Coralline algae requires stable calcium, alkalinity, and magnesium levels to grow effectively. Growth is typically slow but steady under proper conditions. This product is intended to seed and introduce coralline into systems where it is not yet established or to accelerate spread in newer aquariums.

🌱 Propagation

Coralline algae spreads naturally through spores and surface growth:

Can spread onto nearby rock, glass, and equipment over time

Scraping or natural grazing can help distribute spores

Growth accelerates in stable, mature reef systems

Livestock Disclaimer
Due to natural variation between specimens and coverage, the item you receive may not appear exactly like the one pictured. Coralline coverage may vary in density and coloration.

Growth and spread depend on water chemistry, lighting, and overall system stability.

This product is intended as a seeding source rather than a fully established coverage.
