UP W-CA-AS Fine (Nano) Air Stone for Soft, Quiet Aeration

This fine nano air stone breaks pump air into very small bubbles, which dissolve oxygen more efficiently and run more quietly than a coarse stone. Connected to an air pump, it lifts dissolved oxygen for healthier fish and works in both freshwater and marine tanks. The small size suits nano tanks, betta jars, breeder boxes and shrimp setups where you want gentle aeration without a churning column of large bubbles.

Oxygen is a genuine concern in Singapore’s warm tanks: at 27-29C water holds less of it, and demand is highest overnight when plants stop producing. A fine air stone running after lights-out is cheap insurance, especially in densely stocked or heavily planted tanks. The smaller pores will eventually clog with biofilm and minerals, so soak or replace the stone periodically to keep the bubble stream fine and the back-pressure off your pump.
