Air Flow Controller — Perfect Air Flow, Every Time
Air pumps often push out more air than a tank needs, creating strong bubbles that can stress small fish, fry or long-finned fish. An air flow controller lets you turn the flow up or down until it is just right.
It fits on standard airline tubing between your air pump and air stone or sponge filter. Simply turn the control to adjust the flow — gentle for betta and fry tanks, stronger for well-stocked or warm tanks that need more oxygen.
It is also useful when you run several tanks or air stones from one pump, as you can fine-tune the air going to each line. Breeders and fish rooms often use many of them for this reason.
Easy to install and very affordable, it is a small part that helps you create a calmer, healthier tank.
