InWater Plastic Frame Diffuser (12"; 300 × 60 × 25mm)
The InWater Micro Bubble Oxygen Diffusers are made from high-quality ceramic designed for high-efficiency diffusion of oxygen into water. A micro-sized bubble pattern means that bubbles are suspended in the water for longer. The coating is resistant to chipping and peeling and has a proven record of long-term durability. The diffusers are available in aluminum for freshwater applications and plastic for saltwater.
