Product Information

Full details

The Oase BioStyle 115 is an ideal filtration solution for aquarium hobbyists seeking a high-performance, space-saving hang-on-back system that keeps internal tank space clear. It delivers multi-stage mechanical and biological filtration, making it perfect for maintaining water quality in small to medium-sized tanks without requiring external cabinet space. While its compact design is excellent for tight areas, users should ensure the tank rim accommodates a hang-on-back style filter to guarantee a secure, level fit.

FAQs

How often should I replace the filter cartridges?

The integrated indicator will signal when the filter efficiency drops. Generally, replace or rinse based on the bio-load of your aquarium.

Can I use my own filter media?

The unit is designed for Oase cartridges to ensure proper flow and fit, though basic mechanical sponge cleaning is encouraged.

Is this filter safe for shrimp?

Yes, but ensure the intake is appropriately covered or protected if you have very small shrimplets.

Does this require a separate pump?

No, the BioStyle 115 includes an integrated, self-contained pump system.

What is the warranty period?

The Oase BioStyle 115 is backed by a 3-year warranty covering manufacturer defects.

Troubleshooting

The filter is making a rattling noise.

Check that the impeller cover is securely in place and that the intake pipe is not obstructed by gravel or debris.

Water flow is significantly reduced.

Verify if the maintenance indicator shows a need for cleaning; check the intake pipe for blockages and ensure the flow control dial is set to your desired level.

Filter is not hanging level on the tank.

Adjust the spacer located on the back of the unit until the filter casing sits parallel to the aquarium glass.

Pros and Cons

Pros

Compact design saves internal aquarium space
Quiet operation suitable for living areas
Clear maintenance alerts prevent water quality decline
Flexible setup with adjustable flow and intake components
Reliable 3-year warranty for long-term peace of mind

Cons

Requires a rimmed or suitable tank edge for mounting
Filter cartridges are proprietary
May be too powerful for very small, low-flow habitats

Setup, Compatibility & Care

Setup is straightforward: attach the telescopic intake, place the filter on the tank rim, and use the adjustable spacer to ensure the unit hangs perfectly vertical. For optimal care, monitor the integrated maintenance indicator regularly. When the indicator signals, simply slide out the cartridge for rinsing or replacement. Avoid using soap or chemical cleaners, as these can disrupt the biological balance of your aquarium; rinse mechanical media in old aquarium water during your routine water change to preserve beneficial bacteria.
