The Bubble-Gen is a revolutionary way to oxygenate your reservoir tank and circulate your nutrient solution; it removes the need for circulation pumps and air stones.

The Bubble-Gen features a twin jet hydroponic bubble generator with an integral silencer which quietly and efficiently circulates and oxygenates a nutrient tank.

Using atmospheric pressure to pull oxygen-rich air through the input port, it mixes with the nutrients passing through the body of the unit, ejecting an energetic circulating stream of bubbles and nutrients.
