What is it best for?
The air disc is an aeration accessory — it adds oxygen and a fine bubble display to any freshwater or planted tank, and supports fish during hot weather or in heavily stocked tanks. It needs a powerful air pump to drive the fine ceramic. Worried about oxygen? Read signs your fish lack oxygen.
How to set it up
Connect standard 4 mm airline from your air pump to the disc and place it on the substrate — its weight holds it down without suction cups. Use a strong air pump, since fine-pore ceramic needs more pressure than a basic air stone. Give it a gentle clean if output drops over time.
