The pictures show the variations of the water conditions based on many factors since it is an open system, not a closed one like an aquarium or pond.

This river fluctuates between sandy and muddy substrates based on the seasons and downpour rates.

I have fished for tarpon and the likes at this river mouth too, so seeing the fish there is nothing much.

EM proponents are claiming its the success of something that may work in closed systems, for the common cycles of an open river system.

More benefit would have been done picking up the plastic bags instead of just taking pics.
