The City of Fort Collins Golf Division opened its waters to a trial of beneficial phytoplankton and it worked. Phtyoplankton reduced nutrients to levels that were barely detectable and protect from harmful algae blooms, cyanobacteria and nuiscance algae.
A private pond owner in Albany, Ohio set out to keep her new pond safe from harmful algal blooms without chemicals. Beneficial phytoplankton held her nutrients at zero and built a thriving fishery.
At City Park Golf Course, the City and County of Denver traded copper for a biological approach. In about two weeks, beneficial phytoplankton drove ammonia and phosphate on the effluent-fed irrigation pond to zero.
