YauBay Mineral Airstone 20x30x4mm – 12 Pack | Aquarium Aeration

The YB Mineral Airstone is a compact, high-density mineral airstone designed to deliver a consistent stream of fine bubbles across freshwater and marine aquariums. Sold in a pack of 12 at 20x30x4mm each, these are a practical choice for aquarists running multiple tanks or needing reliable aeration across larger setups.

Efficient Aeration

Each airstone produces a steady, even flow of fine bubbles that disperses oxygen efficiently through the water column. This supports healthy oxygen levels for fish and aquatic plants alike, reducing surface stagnation and promoting gas exchange.

Mineral Construction

Built from high-density mineral material, these airstones are made to last. The construction resists degradation over time, maintaining consistent bubble output rather than clogging or collapsing quickly as lower-quality foam alternatives can.

Size and Pack Format

• Each airstone measures 20x30x4mm — a compact rectangular format
• Pack contains 12 airstones
• Suitable for use across multiple aquariums or as replacement stock

Having 12 on hand means you can keep spares ready without interruption to your setup — a sensible approach for any fishkeeper running multiple systems or regular maintenance schedules.
