This Swell Flat Ceramic Air Disc is a large round flat ceramic air stone, suitable for garden ponds.
Used in conjunction with an air pump and 8mm airline, this compact air stone will aid the distribution of oxygen around your garden pond. This is vital in the warmer months, when a raise in temperature can affect the oxygen levels in the water.
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.
