Filter media is the working heart of any aquarium filter – the material that traps waste, removes harmful substances, and helps beneficial bacteria thrive. Oase offers a full range of biological and chemical filter media, as well as replacement cartridges for every filter in the range. Whether you're topping up, replacing, or upgrading, you'll find the right media for your setup here.

Sometimes all you need is the right part. Whether you're adding a heater to your existing setup or replacing a component to keep your filter performing as it should, you'll find the essentials here – designed specifically for Oase aquarium filters.

Our ultracompact, modern surface skimmer ensures clear conditions on the aquarium's surface. It quickly and effectively draws in all flotsam, such as very fine plant detritus, duckweed and, of course, the irritating biofilm that can hinder the gas exchange in aquarium water. The powerful yet quiet motor of the skimmer is infinitely adjustable for flexible control of surface cleaning performance. The integrated basket can be easily removed and provides additional safety for your aquarium inhabitants. The floating ring integrated in the skimmer always stays at the surface. It ensures almost uniform cleaning power despite changing water levels and so can handle longer maintenance intervals.

UVC bulbs naturally lose their effectiveness over time, even when they still appear to be working. Replacing the bulb regularly is one of the simplest ways to keep your water clear and your fish protected.

Good water circulation and oxygen levels are essential for a healthy aquarium. Oase pumps and aerators are compact, quiet, and adjustable – creating the natural water movement and oxygen exchange your fish and plants need, without taking up unnecessary space.

The right lighting brings your aquarium to life – enhancing colors, supporting plant growth, and creating a natural day-to-night rhythm that's good for your fish. Oase LED lighting ranges from clean, true-to-life illumination to smart, app-controlled systems that mimic the full arc of natural sunlight.

Most aquarium fish and plants thrive only within a specific temperature range – and even small fluctuations can cause stress. Oase heaters and thermostats make it easy to maintain the perfect conditions, with reliable, adjustable heating and precise electronic temperature control so you're always in charge of your aquarium's environment.

Regular maintenance is one of the best things you can do for your fish and plants. Oase has everything you need to keep your tank in great shape – from effortless water changes and streak-free glass cleaning to plant care, hose brushes, thermometers, and fish nets. All the little things that make a big difference.

Whether you're away on holiday or simply can't always be home at the right time, the Oase FishGuard automatic feeder keeps your fish fed reliably and on schedule – dispensing exactly the right amount of food every time.

Disconnecting your filter for cleaning shouldn't mean mess or fuss. Oase hose connectors are designed to make removing and reconnecting your equipment quick, clean, and hassle-free – so you spend less time on maintenance and more time enjoying your aquarium

The right substrate does more than look good – it actively supports plant growth, softens water, and creates the natural conditions your plants and fish need to thrive. Oase ScaperLine substrates are made from natural soils, designed specifically for aquascapes and planted aquariums.
