Let's clean up the river filled waste with activated bio carbon and leaves of Terminalia CATAPPA.

TERMINALIA CATAPPA TREE
Concern cope with polluted river water plant waste or household waste a lot of patience for the common good. As a cultural tour and we ecowisata conduct testing mitigate negative impacts for water biota or people who use the river. On the island of Java lush body in Latin Ketapang tree Terminalia CATAPPA used to clear fish pond.

                      Ketapang (Terminalia CATAPPA) is mentioned as a prescription asia to address water issues. Most tropical fish that live in rivers and lakes have water, dark brownish-brown leaves Ketapang and Benefits ..
Ketapang (Terminalia CATAPPA) is a large pagoda-like tree, is native from Malaysia and Indonesia. Green leaves and a bright red after aging.

The leaves will turn yellow and fall aging. By the Indonesia plant is used as a cure skin diseases. Ketapang which has the Latin name: Terminalia Catappa, or commonly referred to as tropical walnut, Badamier, Java Walnuts, wild walnut, Walnuts Indians, Myrobalan, Malabar Walnuts, Walnuts Singapore, Huu kwang, Sea Walnuts, Kobateishi. The tree is known to produce a toxin in the leaves to defend themselves against insect parasites. Dry leaves fell into the river will cause strong brown color. The solution is full of organic acids like humic and tannins.
Dried Ketapang plus bio carbon  can release organic acids like humic and tannins, which can lower the water's pH, and absorb harmful chemicals and provide a comfortable water conditions for the fish.
Humic acid, is a complex mixture of partial decomposition of organic materials. Humic acid from fresh water comes from several sources, most come from the land of the results of decomposition of plants. This substance is washed into rivers and lakes and changed along the way to the sea. Humic acids containing sulfur, phosphorus and nitrogen as well as an assortment of other substances such as Ca, Mg, Cu, Zn and others. Humic acids can be broken down into two groups based on the size and polarity of each component. Smaller fraction more polar called fulvic acid and a larger non-polar usually called humic acid. Humic acid is the end result decaying carcasses of animals and plants that are important in soil fertility.

Acid tannins, lignins and fulvic is a sub-class of humic acid. They all color the water to turn yellow. Humic acid and tannin may be very useful for many people because it can inhibit many kinds of bacteria that endanger the health of pet fish. Humic acids and tannins also can absorb and neutralize toxins from chemicals heavy metals such as zinc, aluminum and copper.
Chemical constituents of Terminalia catappa leaves can reduce the burden on the economy to create green communities.
Since the head of UNEP which now comes from germany hopefully Terminalia catappa leaves can be re-examined and made tablet for easy application.
  Too many gifts ketapang dried leaves into the water can make the lower pH. Then adjust the dry use ketapang to provide optimal effect to the fish.

In English, this plant is known by the names of Bengal almond, Indian almond, Malabar almond, Singapore almond, Tropical almond, Sea almond, Beach Almond, Talisay tree, Umbrella tree, and others.
From various sources.
Hopefully useful for us all.
