Aquarium Air Stone Bubble Diffuser | Fish Tank & Hydroponic Aerator

Upgrade your aquarium, pond, or hydroponic system with this Nano Air Stone Bubble Diffuser. Engineered to produce a uniform mist of ultra-fine nano bubbles, this flat-top aerator disc efficiently boosts dissolved oxygen levels — keeping fish, shrimp, and aquatic plants healthy and thriving. Available in four convenient sizes to suit any setup, from compact shrimp bowls to large planted tanks.

Key Features

• Whisper-Quiet Operation: Designed for bedroom aquariums and quiet office spaces, this aerator disc runs at near-silent levels — ideal for light sleepers and anyone who enjoys a tranquil environment.
• Uniform Nano Bubble Distribution: The flat-top disc design produces an exceptionally even mist of nano bubbles across the entire surface — far more consistent than dome-style alternatives — efficiently raising oxygen levels throughout your tank.
• Four Precise Size Options: Choose from 50 mm (1.97"), 80 mm (3.15"), 100 mm (3.94"), or 130 mm (5.12") diameters. All sizes feature a standard 4 mm (0.16") metal nozzle for a secure connection with standard airline tubing.
• Durable PC & Metal Construction: Built from high-quality polycarbonate (PC) and metal with a high-temperature fired ceramic disc that resists clogging and delivers a clean, steady stream of bubbles with minimal maintenance.
• Low-Pressure Compatible: Operates efficiently even with low-pressure air pumps, making it a reliable choice for delicate shrimp bowls, planted tanks, nursery setups, and hydroponic systems.
• Versatile Use: Compatible with freshwater aquariums, saltwater tanks, garden ponds, hydroponic grow beds, and classroom desktop setups.

Q: How do I clean the air stone disc to prevent clogging?

A: The high-temperature fired ceramic disc is naturally resistant to clogging. For routine maintenance, soak the disc in a diluted white vinegar solution for 30–60 minutes, rinse thoroughly with clean water, and allow it to dry before reinstalling. This helps restore full bubble output and extends the life of your diffuser.
