algaesaltwater

Calcified encrusting algae that paints live rock, glass, and equipment in shades of pink, purple, and white — the hallmark of a mature, healthy reef. Requires stable calcium (400–450 ppm) and alkalinity (8–9 dKH). Does not need dedicated lighting but benefits from reef-level light. Spreads naturally from live rock and purchased plugs.
