Porphyridium cruentum Phytoplankton Culture

Product Overview

Porphyridium cruentum is a striking red microalgae prized in reef aquaculture for its exceptional nutritional and bioactive profile. Rich in phycoerythrin, omega-3 fatty acids, and sulfated polysaccharides, it delivers benefits that go far beyond basic nutrition — actively supporting coral pigmentation, immune function, and overall reef health.
Unlike green and golden phytos, Porphyridium’s unique red pigmentation makes it a highly visible, palatable feed that corals, feather dusters, clams, and other filter feeders readily consume. Its sulfated polysaccharides have been shown to support mucus production and stress resilience in coral tissue, making it a valuable addition to any reef feeding regimen.
