Aqua One Airstone PVC Encased Green 45cm — Compact Weighted Aeration Bar & Oxygen Enricher for Mid-size Aquariums
The Aqua One Airstone PVC Encased Green 45cm (SKU: 10133) provides efficient aeration and oxygen enrichment for compact and medium aquarium setups. Constructed with a protective weighted green PVC body, this 45 cm airstone sits flat along the substrate floor, delivering a wall of micro-bubbles that improves water movement and surface gas exchange.
Sized to fit smaller display tanks or targeted zones in larger aquariums, the 45 cm airstone helps eliminate stagnant water pockets and prevents oxygen drops in warm or heavily populated aquariums. Its tough PVC outer casing protects the internal stone against wear, ensuring reliable performance.
