Usage & Maintenance Instructions

To achieve the best possible performance and the finest bubbles from your new cylinder air stone, please follow these simple steps:

Crucial Pre-Soak: Before connecting the air stone to your air pump, completely submerge the stone in a container of aquarium water for at least 15 to 30 minutes. This allows water to displace the air trapped inside the microscopic pores, ensuring an even distribution of fine bubbles right from the start.

Installation Safety: Always remember to install a check valve inline between your air stone and your air pump. This prevents water from siphoning back into your electrical equipment during a power outage.

Routine Cleaning: Over time, natural organic buildup, algae, or mineral deposits may clog the pores, reducing the bubble output. Simply remove the air stone, gently scrub the surface with an old toothbrush under clean running water, and reinstall to restore maximum airflow.
