Are 'cyanobacteria,' 'blue-green algae,' and 'harmful algal blooms' the same thing? Mostly — but the distinctions matter for treatment decisions, regulatory compliance, and public communication. Understanding the vocabulary is step one. Taking biological action is step two — order Hydralife's live phytoplankton at hydralife.org.

Not all algae are equal — and confusing beneficial phytoplankton with toxic cyanobacteria leads to costly, counterproductive management decisions. Understanding the difference is step one in effective HAB management. Hydralife's live phytoplankton is the biological solution — $20/gallon, ships overnight. Order at hydralife.org.

Unlike most algae, toxic cyanobacteria can fix nitrogen directly from the atmosphere — meaning they can bloom even after phosphate is reduced. This is precisely why phytoplankton-based competitive exclusion, which targets light and all available nutrients simultaneously, is the most effective biological HAB defense available.
