Description

Restore Airflow with the Correct Replacement Disc

The Aquascape Pond Aerator Replacement Aeration Disc replaces one diffuser on a compatible small-pond aeration system. Connect it to existing 3/16-inch airline tubing and position it in the pond so the air pump can deliver bubbles that help circulate and oxygenate the water.

Compatibility Note

Aquascape states that this disc can be used with many traditional pond and aquarium aerators. Before pairing it with a different pump, confirm that the system uses compatible 3/16-inch tubing and is intended to operate a diffuser of this type.

Installation and Seasonal Placement

  1. Turn off the aerator. Unplug the air pump before inspecting or servicing the system.
  2. Connect the airline. Attach the existing 3/16-inch aeration tubing to the replacement disc.
  3. Position the disc. For normal warm-season use, place the disc on the pond bottom. In multi-disc systems, space the diffusers apart to improve circulation throughout the pond.
  4. Secure it if needed. Small rocks or gravel can help hold the disc and airline in position while keeping the installation visually discreet.
  5. Restart and check the system. Restore power according to the aerator’s instructions and confirm that air is flowing from the disc.

Winter Placement Tip

When operating the Aquascape aeration kit during winter, position the disc approximately 1 to 1½ feet below the water surface rather than at the deepest point. Aquascape advises this placement to avoid disturbing the warmer lower-water zone where fish overwinter.

Frequently Asked Questions

Is this a complete pond aeration kit?

No. This product is one replacement aeration disc. It does not include an air pump, airline tubing, check valve, or other kit components.

Which Aquascape aerators use this disc?

It is the specified replacement disc for the Aquascape 2-Outlet Pond Aeration Kit, model 75000, and the 4-Outlet Pond Aeration Kit, model 75001.

What size airline tubing does it accept?

The manufacturer specifies 3/16-inch airline tubing.

Can I use it with a different pond or aquarium air pump?

Potentially. Aquascape states that it can be used with many traditional pond and aquarium aerators. Confirm the tubing connection and suitability of the air pump before ordering.

How many discs are included?

One replacement aeration disc is included.

Is the 2,000-gallon rating for this disc?

No. Pond-volume and maximum-depth ratings apply to complete aeration systems, not to this replacement disc by itself.

What should I check if airflow is weak or stops?

Check that the airline is not kinked or restricted and that the check valve points in the direction of airflow. If the problem continues, the air pump’s diaphragm cartridge may also need attention.

Where should the disc be placed during winter?

Aquascape recommends placing the disc about 1 to 1½ feet below the surface during winter rather than at the bottom of the pond. Follow the complete aerator kit instructions for seasonal operation.
