OASE

Why OASE

OASE sits at the premium end of pond and aquarium equipment, and the range stocked here reflects that: sealed canister filters with priming pumps, energy-managed pond pumps, and complete aquarium sets rather than budget components.

Filtration built for planted tanks

The BioMaster canister filters use a removable pre-filter module that can be cleaned without opening the main canister, so the biological media is left undisturbed. They come in 250, 350, 600 and 850 sizes, each also available as a Thermo version with the heater built into the canister — which keeps a heater out of view in an aquascape.

Pond pumps rated for continuous duty

AquaMax Eco Classic pumps run from 2500 to 17500 and are built for filter and watercourse duty rather than intermittent fountain use. The Aquarius Universal Premium and Premium ECO range covers fountain and feature work from 3000 to 12000.

Complete aquarium sets

ScaperLine 60, 90 and 100 and StyleLine 125 and 175 are sold as sets in black, grey or white, which removes the guesswork of matching a cabinet, hood and lighting to a tank.

How to choose an OASE filter

1. Match the filter to tank or pond volume, then size up. A BioMaster 350 on a 250L tank gives you headroom as the stocking level grows; running a filter at its stated maximum leaves nothing in reserve.
2. Decide whether you want the heater inside the filter. The BioMaster Thermo models put the heating element in the canister, which frees up tank space and keeps hardware out of an aquascape.
3. For ponds, separate the jobs. BioSmart and Biopress handle biological filtration; AquaSkim pulls surface debris before it sinks; PondoVac lifts what has already settled.
4. Check the pump duty. AquaMax Eco Classic is built for continuous filter and watercourse running. Aquarius is aimed at fountains and features.
5. Add UV only if you have green water. The Filtral UVC units combine pump, filter and UV in one housing for smaller ponds; larger ponds are better served by a separate filter and clarifier.
