Swell 50mm Jap Ball Airstone
A popular, weighted airstone, this Swell 50mm Jap Ball Airstone sits at the bottom of your pond and helps oxygenate your pond water, for the benefit of the oxygen breathing life inside.
Product Information
The Swell 50mm Jap Ball Airstone is a top quality, weighted air stone that produces a fine, even stream of bubbles in your pond.
Attached to airline and an air pump (not included), the resultant bubbles will promote the distribution of oxygen within your pond to boost the water conditions and the health of both fish and plants. This is especially important in the summer months when increasing temperatures can affect the level of oxygen in the water.
- Designed for use with 4mm ID / 6mm OD airline.
- Dimensions: 50mm
