Stechlinsee: Kann Ultraschall Blaualgen im Wasser verschwinden lassen?
In Neuglobsow treffen die Kontrahenten aufeinander: Einer behauptet, mit Ultraschall Blaualgen im Wasser zu beseitigen. Dem anderen fehlen die Beweise. Was hat es gebracht?
Wasserkundler Hartmut Wassmann will die Reichweite seiner Ultraschallsonde im Stechlinsee testen.

Wassmanns Teamkollege Dr. Roman Klemz packt die Geräte in die Boote und bringt die E-Motoren an.
