This dome air stone measures at 10" in diameter, and 7cm in height, and is to be used with 8mm airline (not supplied).
This air stone is suitable for garden ponds and, when used in conjunction with an air pump, will supply air throughout your pond, increasing the oxygen in there and ensuring a good, healthy environment for the inhabitants, especially during warmer months.
Oxygen is of course a vital element for living things including your pond fish and plants. It is also essential to boost the general health and clarity of your pond. The stream of fine bubbles from this flat air stone will carry the oxygen up and around the pond, boosting natural processes and improving the condition of your pond.
