Oxygen equals Life. This is all the more true in a garden pond. A well aerated garden pond will feature less algae, healthier fish and clearer water. Good pond aeration helps filtration processes, improves the water quality, prevents the pond from becoming stagnant and helps fish to breathe, particularly in warmer weather when the dissolved Oxygen in the water is even less. The O2 Plus air pumps from Pond One are specifically designed for outdoor use and are resistant to the perils the UK weather can throw at them. Fitted with 10m cable, installation is made simple in comparison to other models around. O2 Plus 4000 and 8000 air machines are extremely powerful units. With outputs of 35 and 70 liters per minute these are suitable for seriously large ponds or filters to stimulate aerobic activity or simply to add more oxygen to multiple points around the pond. With the design based upon the Aqua One indoor units these units are fantastically quiet during operation. Outlet size is 1/2". Each unit comes with a 4, 8 or 10 gang splitter allowing multiple air stones to be run simultaneously.
