Layer aeration is similar structurally to hypolimnetic aeration. However, water is selectively drawn into the aerator from several depths, aerated, blended and returned at an intermediate depth. Hence, returned aerated flow is at an intermediate temperature (between temps of aerator intakes) and is neutrally buoyant. This is useful for creating a distinct aerobic water layer for cold water fish, zooplankton refuge habitat, etc.
Air diffusers inside the aeration tower pump, aerate and blend water from selected depths.
