Description
The finer the bubbles, the larger their contact area with the water. This nano diffuser replaces the classic air stone with a 6 cm disc that produces a dense cloud of micro-bubbles, more discreet to look at and quieter than big bubbling.
The clear PC body sticks to the glass with two suction cups and connects to standard air-pump tubing (pump not included: our mini USB pump suits a small tank). About 7 cm tall, 100 g. Rinse the disc in clean water when the bubbles get bigger.
Good to know: a fine diffuser needs a little more pressure than a coarse stone; with a very weak pump, bubble output will be reduced. It does not filter the water, it only improves oxygenation and surface movement. Avoid placing it right under floating plants or in a betta tank, as bettas prefer calm water.

Frequently asked questions
Do I need an air pump?
Yes, the diffuser only spreads the air a pump sends. It fits standard 4 mm aquarium air tubing.
How do I clean it?
When bubbles get bigger the disc is clogging: rinse it in clean water and brush gently, no soap.
