Fine Nano Hose Products Description Aeration hose's tiny pore size creates extremely small diameter bubbles. The smaller a bubble of air the more efficiently it t ransfer oxygen into water(more surface area). Small bubbles also take take longer to rise once they are introduce into the water.Slowing rising, small-diameter bubbles mean more contact with the water and a much higher rate of oxygen transfer.By creating significantly smaller bubbles, more efficiency,aeration tube are able to deliver high rates of oxygen transfer and energy efficiency.
