Product description Nano Bubble Air Diffuser produces ultra-fine micro bubbles that dissolve more oxygen into aquarium water compared to standard air stones. This creates a smooth, even curtain of bubbles that enhances water circulation and helps maintain a healthy environment for fish and shrimp. These diffusers require a stronger air pump than regular air stones. A more powerful pump will generate a full wall of micro bubbles, while a small or weak pump may only produce a few bubbles at the front of the stone. Before use, the diffuser must be soaked completely for at least 1 hour to allow proper air flow through the ceramic pores. Clean the diffuser regularly with a brush to remove debris or algae, as the fine holes can become clogged over time. Each diffuser includes one suction cup to help secure the air pipe and prevent it from floating. Compatible with standard 4/6 mm air tubing (4 mm inner diameter, 6 mm outer diameter). Air pipe and pump are not included. Colour: Black base, white stone. Safe for all aquarium pets and plants. Directions 1. Soak the diffuser completely in clean water for at least 1 hour before first use. 2. Connect to an aquarium air pump using a 4/6 mm air hose (4 mm inner, 6 mm outer diameter). 3. Use a strong air pump for best results. Weaker pumps may produce fewer or uneven bubbles. 4. Place the diffuser at the bottom of the tank and secure the air pipe with the included suction cup. 5. Clean gently with a soft brush every few weeks to remove debris and prevent clogging. Avoid dropping or using sharp tools to prevent ceramic damage.
