Do You Really Need OASE Biomaster Review? Pros & Cons
Choosing the right aquarium filter is a crucial step for any aquascaper. The OASE Biomaster is one of the most talked-about canister filters in the hobby. But do you really need it for your aquascape? In this in-depth review, we break down the pros, cons, and core features so you can make an informed decision and achieve pristine water in your planted aquarium.
What Is the OASE Biomaster?
The OASE Biomaster is a line of external canister filters designed for freshwater aquariums. Known for their advanced filtration technology, these filters are especially popular among aquascapers who want crystal-clear water, healthy plants, and thriving fish. With models like the Biomaster 250, 350, 600, and 850, OASE covers everything from nano tanks to large display aquariums.
Key features include the EasyClean prefilter module, integrated heater (on Thermo models), multi-stage filtration, and near-silent operation. But how do these features translate into real-world performance for aquascaping enthusiasts?
OASE Biomaster Pros
1. Superior Filtration
The Biomaster utilizes mechanical, biological, and chemical filtration, ensuring your aquascape stays free from debris and ammonia spikes. This triple-layered approach is ideal for lush planted tanks where water clarity is essential for aesthetic appeal and plant health.
2. Innovative EasyClean Prefilter
The standout feature is the EasyClean prefilter module. It allows you to clean the filter’s first stage without dismantling the entire canister. This saves time and prevents disruption to beneficial bacteria, which is crucial during regular aquarium maintenance.
3. Integrated Heater Option
The Biomaster Thermo models come with an integrated heater. This keeps your aquarium visually tidy, eliminates the need for in-tank heaters (which can spoil aquascape layouts), and ensures even heat distribution—crucial for sensitive plants and fish.
4. Quiet Operation
OASE is known for their silent running motors. The Biomaster operates quietly, making it ideal for living rooms, bedrooms, or office setups where noise could be an issue.
5. Flexible Media Options
The Biomaster comes with high-quality filter media, but it’s also adaptable—letting you customize for specific aquascaping needs, like boosting biological filtration with more bio-media or adding activated carbon after using medication.
OASE Biomaster Cons
1. Premium Price Tag
Compared to entry-level canister filters, the Biomaster is a significant investment. While you do get advanced features and build quality, the price can be a drawback for beginners or those on a tight budget.
2. Larger Footprint
The Biomaster is relatively large, especially compared to hang-on-back filters or smaller canister models. If you’re working with a modest cabinet or have limited space beneath your aquarium, double-check dimensions before purchasing.
3. Slightly Complicated Setup
Although most users find the Biomaster easy to maintain, the initial setup has more steps than basic filters. The extra features, like the prefilter and integrated heater, add complexity—so set aside enough time for installation and follow the manual carefully.
4. Availability of Spare Parts
Some users note that certain replacement parts (like prefilter sponges or O-rings) may not be as readily available as mainstream brands. It’s worth checking local aquarium stores or reputable online shops for OASE-specific supplies.
Is the OASE Biomaster Worth It for Aquascaping?
If you’re serious about high-quality aquascaping—especially planted tank setups like Nature Aquariums, Iwagumi, or Dutch styles—the OASE Biomaster offers features that can elevate your aquarium experience. Its superior water polishing, easy maintenance, and sleek look (especially the Thermo models) are all strong selling points.
However, for smaller tanks under 20 gallons or simple low-tech setups, you might be better off with a smaller filter or even a sponge filter, as covered in our best aquarium filters guide.
OASE Biomaster vs. Other Canister Filters
How does the Biomaster stack up against popular competitors like the Fluval 407, Eheim Classic, or Sunsun HW series?
- Ease of maintenance: The prefilter module sets it apart, making routine cleaning far less invasive.
- Integrated heater: Removes visual clutter, which is great for those who value aquascape aesthetics.
- Noise: Quieter than most in its class, although premium rival filters are close.
- Customization: Comparable to top-tier options, with ample space for tweaking filter media.
- Price: Biomaster tends to be more expensive, but frequent sales and bundles can offset costs.
What Other Aquascapers Say
Enthusiasts on aquarium forums and social media agree that the Biomaster’s prefilter and overall user-friendly design make it a favorite among planted tank hobbyists. Some mention the initial cost, but many feel the premium features and reliability pay off in the long run.
“The EasyClean prefilter is a game changer—makes maintenance so much easier and less stressful for fish & plants. Totally worth it for high-tech tanks.”

Final Verdict: Do You Really Need an OASE Biomaster?
If your goal is a thriving, visually stunning aquascape with minimal filtration hassles, the OASE Biomaster is hard to beat. Its performance, innovative features, and low-noise operation justify the investment for most intermediate and advanced aquascapers.
That said, if your budget is tight or you’re managing a very small tank, consider alternatives that fit your specific needs. Ultimately, the best filter is the one that matches your aquascape’s size, bioload, and your maintenance style.
