Improve aeration while increasing aquarium aesthetic appeal! Marina Deluxe Bubble Disk is an economical addition to your aquarium that creates an eye-catching visual display of bubbles that enrich oxygen content for better fish health. Disk-shaped airstone diffuser produces a cylindrical bubble column that rises to the surface to increase surface agitation for greater overall water circulation and aquarium gas exchange. A decorative touch ideal for any aquarium. Airstones, curtains, and diffusers require an air pump and airline tubing for use (sold separately).

Note: The volume and pressure output of your air pump will determine how large an area of the disk will release bubbles.

Directions:

1. Attach airline tubing to Bubble Disk and place in aquarium.
2. Allow Bubble Disk to soak for 15 minutes before turning on air supply.
3. If algae buildup reduces airflow after extended use, remove Bubble Disk from aquarium and clean surface with a stiff brush.
