Neptune Hydroponics Air Pump

These Neptune Hydroponics air pumps are used to add a constant flow of oxygen into your water tank, keeping the nutrients and fertilizers in constant movement as well as increasing nutrient absorption.

Once temperatures go above 25ºC, the presence of oxygen in water is lowered significantly, which makes it much harder for your plants to successfully feed – they need plenty of oxygen to do so.

Both models are almost identical, although is twice as strong as the other, meaning that it produces twice as much air. It also has two outlets rather than one, allowing you to oxygenate two tanks at once or have them set up at a specific distance, which can increase efficiency in large tanks.

You’ll need a diffusor stone/air stone in order to properly distribute air inside the tank itself, or else the air will simply bubble to the top. Air stones are used to pop the air bubbles and keep the oxygen in the water rather than having it float up to the top as a bubble.
