(CLICK on the link below the picture for more product details and shopping options)
An air pump used in conjunction with an air stone is an excellent way to add oxygen to the nutrient solution in your hydroponic growing system. This will result in a healthy root system and increased growth rates. The Air Curtain is extremely permeable, producing a full curtain of bubbles without strong air resistance. There is no harmful back-bressure created to damage pump diaphragms. A 35'' Air Curtain works well for a 35 gallon reservoir.
