The efficiency of the oxygen exchange into the water depends on the bubble size and the duration of the bubbles in the water. Coarse bubble diffusors generally have an oxygen exchange efficiency of 1% per meter due to their low surface area to volume ratio. Fine bubble diffusors generally have an efficiency of 5% per meter. The deeper the diffusors are installed in the water, the more oxygen is exchanged into the water.
