Floating Fountains are well suited to ponds and lakes, particularly in areas where the water depth is too great to install a standard submersible pump, or where the pond floor is heavily silted or clay lined. A floating fountain or lake aerator will automatically compensate for changes in water levels. The OASE Pond Jet ECO Floating Fountain provides a 3 metre high, 3 metre diameter, single tier, 12 jet fountain display, with very energy efficient motor operation. The Pro-Jet Floating Fountains are capable of substantial ornamental display heights of up to 16.5 metres. The OASE Air Flo LM is designed to aerate large ponds or lakes, in addition to providing a voluminous, decorative water display.
