Find a productProduct description
This cylindrical air stone is intended for large aquarium and pond setups, from 750 to 5000 litres, where a single pump has to supply oxygen across a substantial water volume. It is built to connect to the standard 4/6 mm airline that the supplier includes with each compatible air pump, so it can be fitted without adapters.
Why it matters
- Dimensions of 20x151 mm give a long diffusing surface, which the supplier attributes to good gas dispersion in water.
- Compatible with any air pump rated from 5 to 150 l/min, covering a wide range of pump sizes.
- According to the supplier, it is chemically neutral, does not alter the gas composition, and does not change water pH.
- The supplier states that the product is original, has been tested repeatedly, and holds safety certificates.
