Key Features & Benefits

• Premium Sintered Carborundum: Manufactured using a high-temperature sintering process, making the stone exceptionally hard, durable, and completely resistant to acid, alkali, and ozone.

• High Dissolved Oxygen: Engineered to produce a high volume of micro-bubbles, boasting a highly efficient gas output of 1.8 Liters per minute.

• Complete Accessory Kit: Includes a clear one-way check valve (to prevent water from siphoning back into your air pump during a power outage), a grey air flow control valve, and a suction cup for secure placement.

• Washable & Reusable: Designed for long-term use. If the pores become clogged with algae or debris over time, it can be easily scrubbed and washed to restore full bubble output.

• Universal Metal Connector: Features a sturdy, built-in metal nozzle that securely fits standard silicone or PVC airline tubing.

Usage & Maintenance Instructions

To get the absolute best performance and finest bubbles from your A20080 Air Stone, please follow these simple steps:

1. Crucial Pre-Soak: Before connecting to your air pump, soak the air stone completely in aquarium water for at least 2 hours. This allows water to displace the air trapped inside the microscopic pores, ensuring an even distribution of fine bubbles across the entire disk.

2. Installation: Connect your airline tubing to the metal connector. For safety, install the included clear check valve inline between the air stone and your air pump to prevent water backflow. Use the grey control valve to adjust the bubble intensity to your liking.

3. Routine Cleaning: After prolonged use, organic buildup or dirt may clog the micro-pores, leading to a reduction in bubbles. Simply remove the air stone, gently scrub the surface with a brush under clean water, and reinstall to restore its original efficiency.
