Hozelock Pond Air Pumps
The oxygen levels in ponds depends on quite a few variables water surface area, number of fish, temperature, water movement to mention a few. So if one or more of these factors alter it can greatly affect the oxygen in your pond. If the oxygen level in pond water drops the fish will not look as alert and be swimming in a very lethargic manor and most of the fish will be seen gulping air from the surface, do not confuse this with the fish just mouthing the water surface this is natural and usually the fish just taking insects off the surface.
As most of us myself included have added that extra fish too many and most ponds are overstocked anyway it is a good idea to add oxygen to the pond via a pond air pump. ValueAquatics can highly recommend the Hozelock Air Pumps rated at 45 Lpm (1820) to the 75 Lpm (1786).
The pumps are weather proof and have been designed to be left outdoors.
These pumps come complete with a 10cm air stone which allows maximum diffusion of the air into the water. The pump comes with a metal manifold with 12 outlets so that extra air stones can be added if necessary.
