Swell 50mm Japanese Ball Airstone

The Swell 50mm Japanese 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.
