Why has a section of Taal Lake gone green?

Some residents in Talisay and Tanauan, Batangas, were left concerned after water from a section of Taal Lake turned green.

According to "Kuya Kim Ano Na?" on "24 Oras," Thursday, the residents, including some fishermen, had qualms about the lake's green water.

Some worried that it may not be safe to venture out into the lake, while others wondered whether the water changing color was connected to the recent activity of Taal Volcano, which emitted volcanic smog and affected Batangas and neighboring provinces.

However, the lake's green water is not a cause for concern.

In the report, the Bureau of Fisheries and Aquatic Resources (BFAR) - CALABARZON cleared that Taal Volcano's recent activity has nothing to do with Taal Lake's water turning green.

The green water, in fact, is caused by algal or algae bloom, also known as "lumot."

"It's a natural process. Pag masyadong mainit ang panahon at sagana sa nutrient 'yung tubig, nagkakaroon talaga ng algal bloom," said Sammy Malvas, regional director of BFAR-CALABARZON.

"Pagkain din ng isda, pero syempre 'yun lang din po ang ating babantayan kasi sa proseso kasi niyan mag-b-bloom tapos mag-d-die off din 'yan."

Malvas added that algae bloom usually only lasts for a couple of days.
