The Smart Solar Solar Oxygenator is an ingenious air pump suitable for small to medium ponds. Working via solar power these air pumps oxygenate pond water when oxygen levels are depleted. The 2 stone pump oxygenates when the sun is shining and works on ponds up to 5000 litres.
During hot weather the water temperature rises and its ability to dissolve oxygen reduces. In theory this will be at its worst during the day when the sun is beating down on your pond but there are other mitigating factors.
This Air Pump has been cleverly designed to operate automatically whenever the sun is hitting the solar panel.
