Ok, my algae issues are not so bad after all...

"But Wang Liqing, a marine biology professor at Shanghai Ocean University, said in a phone interview that the bloom could be caused by pollution, which deposits excessive nutrients in the water and causes algae to grow at abnormal rates. China's east coast is highly industrial."

Someone asked me about this in person and I said the same thing.
Some environmental protection and consideration is needed in huge massive way.
