Whether you’re building a planted tank or setting up your first aquascape, this guide will help demystify filter jargon, installation tips, and maintenance tasks so you can focus on creating your underwater masterpiece.
What Is the Oase Biomaster?
The Oase Biomaster is a line of external canister filters designed for freshwater and planted aquariums. Known for their ease of use, powerful filtration, and innovative features, Oase Biomaster filters are a popular choice among both beginners and seasoned aquascapers. The most popular models include:
- Oase Biomaster 250
- Oase Biomaster 350
- Oase Biomaster 600 (also known as the Thermo variant with integrated heater)
Each model offers different capacities, but all share the core functions that make the Biomaster line stand out—simple maintenance, quiet operation, and reliable biological filtration.
Key Features of the Oase Biomaster
What sets the Oase Biomaster apart from other aquarium filters? Here are a few standout features that make it ideal for aquascaping beginners:
1. EasyClean Pre-filter Module
Unlike traditional canisters, the Biomaster features a removable EasyClean pre-filter. This lets you clean the filter sponge without dismantling the entire canister, reducing downtime and mess—perfect for busy aquascapers.
2. Integrated Heater Option (Thermo Series)
The Thermo models come with a built-in heater, providing stable temperature control while decluttering your tank. This is a great option for aquascapers focused on plant growth or keeping tropical species.
3. Steady, Adjustable Flow Rate
Water flow can be fine-tuned to suit delicate plants, shrimp, or high-energy fish. Balanced flow is critical for aquascaping success, as stagnant water can lead to algae and plant issues.
4. Silent Operation
Thanks to high-quality engineering, Biomaster filters are virtually silent—ideal for living rooms, bedrooms, and quiet office spaces.
5. Sturdy Build and Reliable Performance
With robust construction and German engineering, the Oase Biomaster is built to last, giving beginners peace of mind as they learn the ropes of aquarium care.
Setup: How to Install the Oase Biomaster
Setting up your Oase Biomaster is straightforward, even for those new to aquarium hardware. Follow these basic steps:
- Unpack all filter components, checking for the canister, hoses, intake/outflow pipes, and media.
- Assemble filter media as instructed—most models come pre-loaded with coarse and fine sponges, biological media, and carbon.
- Connect hoses and secure them to the intake and outflow piping.
- Place the canister under your aquarium (below the water level) to ensure efficient siphoning and reduce air in the system.
- Prime the filter using the built-in priming pump to start water flow. Double-check for any leaks.
- Plug in the filter, making sure the flow rate is adjusted for the needs of your aquascape or fish community.

Maintenance: Keeping Your Biomaster Running Smoothly
Once your filter is up and running, regular maintenance ensures its longevity and keeps your aquascaping plants healthy.
Cleaning the Pre-filter
The EasyClean module makes this task a breeze—simply remove, rinse under tank water, and replace. We recommend cleaning the pre-filter every 2-4 weeks depending on tank bioload.
Media Replacement
Sponge and biological media should be rinsed with aquarium water every 1-2 months or as needed. Replace carbon every 4-6 weeks if you’re using it.
Deep Cleaning
Perform a full canister clean every 3-6 months to prevent buildup that can slow flow and reduce filter efficiency. Always avoid using tap water on biological media to preserve beneficial bacteria vital for a balanced aquarium.
Pros and Cons of the Oase Biomaster
| Pros | Cons |
|---|---|
| EasyClean maintenance system | Higher price than some entry-level filters |
| Quieter than most canisters | Larger size requires under-tank space |
| Thermo version saves space in-tank | Some users report minor priming difficulties |

The Oase Biomaster is an excellent choice for:
