Hozelock 4500 Pond Air Pump
Launched in 2012 from Hozelock and instantly a bestseller, this air pump is perfect for most garden ponds.
Adding oxygen into a fishpond is very important for fish health, particularly in densely stocked ponds and in the summer months when oxygen levels decline.
Air pumps can also be used to circulate water and help prevent the pond from freezing in winter.
