Algae Control Without Chemicals - How it Works

The Quattro-DB, is a state of the art device for algae and biofilm control. The Quattro (4 Directional) – DB (Dual Bandwidth) offers features not found before in these types of devices.  A radial sound output is achieved with two piezo sound emitters that can operate in two different bandwidths for better control of green algae and diatoms in the lower bandwidth and blue-green algae in the higher bandwidth, all accomplished with one device.
