solar oxygenating pump
A solar oxygenating pump is an air pump, powered by direct sunlight, which adds oxygen to ponds providing a healthier environment for fish. The advantages of such an oxygenator are that the pump has no operating costs, requires no power outlet or wires to operate it, and works hardest when it is needed most – on hot summer days when the sun is beating down and the oxygen content of the water in the pond would otherwise be at its lowest.
The solar pump illustrated here adds oxygen to a pond via two air stones, which are provided. It also comes with a a multi-fixing panel holder, two 6 foot 5 inch (2 meter) air lines, and 16 ftee (5 meters) of cable.
