Oase Aquarius Fountain Set Classic 750

Oase Aquarius Fountain Set Classic 750

A complete compact fountain-pump set with three interchangeable water patterns

The Aquarius Fountain Set Classic 750 is an entry-level Oase fountain package for small garden ponds, tubs and formal water features. It combines a submerged pump, telescopic riser and three nozzle heads so you can create a water bell, simple fountain or tiered display without assembling the components separately.

The telescopic extension helps bring the nozzle to the correct height above the water surface and the integrated adjustment lets you balance the display after installation. Its 720 l/h maximum flow and 1.1m maximum head make it a small decorative set, not a filter pump or a high fountain for a large exposed pond.

Choosing the right size

Check both the desired spray diameter and the available water depth. The fountain should land back within the pond even in a breeze, and the pump must remain fully submerged. Leave room around the intake so it does not sit directly in silt or draw loose planting media.

Start by deciding what the display or circulation point must achieve. A small bubbling ornament needs much less water than a raised blade, a broad cascade or a tall fountain jet. Measure the vertical difference from the water surface to the highest outlet, then allow for friction. Narrow hose, long runs, sharp elbows, restrictive valves and undersized fittings all reduce the delivered flow.

If the result is critical, use the manufacturer’s performance curve rather than choosing only from the product name. It is usually better to keep the pipe bore generous and control a small amount of surplus flow than to make a marginal pump work at the edge of its capability. Do not use a valve on the inlet side and never allow the pump to run without water.

Installation details that make a real difference

• Level the pump securely so the riser remains vertical.
• Adjust the telescopic section so the nozzle sits just above the surface.
• Keep the spray well inside the pond to limit wind loss and topping-up.
• Clean the nozzle openings and intake when the pattern becomes uneven.

Keep the pump accessible. Even a reliable water-feature pump needs its intake inspected and cleaned, particularly in shallow features where leaves, blanketweed and mineral deposits collect quickly. Isolate the electricity before touching the pump, cable or nozzle assembly, and use an outdoor supply with appropriate RCD protection.

Frequently asked questions

Does maximum flow mean the amount I will receive?

No. It is a laboratory figure at minimal head. The installed flow falls as lift and pipe resistance increase.

Can I reduce the flow?

A valve may be fitted on the outlet where the instructions permit it. Never throttle the inlet. If regular adjustment is important, compare a purpose-designed controllable pump.

Can the pump stay outdoors in winter?

Follow the model instructions and prevent freezing. A pump left in service must remain sufficiently deep and ice-free; a removed pump should be cleaned and stored as the manufacturer directs.
