Fountains and other surface aeration units are designed to provide oxygen at the surface and distribute it throughout the water column. They achieve this by moving water at a high rate. These units can virtually eliminate any chance for thermocline formation in bodies of water up to 8 feet deep. There is no break-in procedure required when installing a surface aerator. In addition to providing oxygen, surface aerators can also be aesthetically pleasing. ATAC offers a wide variety of fountain and spray nozzle options to suit your preferences. Lighting options are also available allowing these units to be enjoyed any time of the day.
