Largest algae bloom ever seen in China turns beaches green

Published: July 5, 2013 at 2:32 PM
QINGDAO, China, July 5 (UPI) -- Beaches on the Yellow Sea have turned green in the largest algae bloom ever seen in China, possibly from pollution from agriculture or industry, experts said.

Authorities in the city of Qingdao used bulldozers to remove 7,335 tons of algae from beaches, China's state-run Xinhua news agency reported Friday.

The summer algae bloom has become an annual occurrence beginning 6 years ago, with this year's outbreak covering 11,158 square miles.

While not toxic to humans or animals, the algae blocks sunlight from entering the ocean and can reduce oxygen in the water, suffocating marine life.

An abundance of nutrients in the water can trigger such blooms, and the Chinese outbreak may be the result of industrial pollution, a British expert said.

"Algal blooms often follow a massive discharge of phosphates or nitrates into the water," University of Cambridge researcher Brenda Parker told the British newspaper The Guardian.

"Whether it's farming, untreated sewage or some kind of industrial plant that is discharging waste into the water," she said, such a dramatic change in the ecosystem was probably not natural

"That would probably be an indicator that something is a little bit unbalanced."

No it was that green last year

But then an odd thing happened...  It cleared itself and set up an eco system (I'll detail that later was rather amazing)

But this year I stopped it in time with a gallon of hydrochloric acid. Seems the pool guy is only coming once every two weeks now instead of once a week. When he tested it was down to zero chlorine.

Luckily I caught it in time because in 117F heat in full sun you cab get an algae bloom in a few hours and would have to drain the pool   and that is 48,000 gallons
