6. Operating Instructions

Once the filter is properly installed and submerged in water (with the air tube above water), plug in the power cord. The filter will begin circulating and purifying the water.

Adjusting Aeration:

The filter includes an adjustable air valve to control the amount of oxygen bubbles released into the water. This helps increase dissolved oxygen levels.

  • To increase bubbles: Turn the air valve counter-clockwise.
  • To decrease/stop bubbles: Turn the air valve clockwise.
