FAQs

Is the Oase BioStyle 75 safe for shrimp tanks?

Yes, but ensure the intake is protected with a pre-filter sponge to prevent smaller shrimp from being pulled into the suction pipe.

How often should I change the filter media?

The maintenance indicator provides the best guidance; typically, fleece and carbon cartridges are replaced every 4 to 8 weeks depending on tank bioload.

Can I use this in a saltwater tank?

Yes, the BioStyle 75 is compatible with both freshwater and marine environments.

Does the filter need to be primed?

It is recommended to fill the filter reservoir with water before turning on the power to ensure the pump starts smoothly.

What is the maximum aquarium size for this filter?

This model is specifically designed for aquariums up to 70 litres.

Troubleshooting

The filter is making a rattling or loud noise.

Check the impeller chamber for trapped debris or loose housing parts; ensure the telescopic pipe is fully seated.

Flow rate has significantly decreased.

The filter cartridge is likely clogged. Remove and rinse the foam or replace the filter media as indicated by the maintenance gauge.

The unit is leaking water over the back.

Check the intake pipe and filter housing for blockages that may be causing water to bypass the media basket.

Pros and Cons

Pros

  • Extremely compact and space-efficient for small setups
  • Easy to install on the back of most aquarium rims
  • Maintenance indicator removes the guesswork from cleaning
  • Quiet motor operation is ideal for quiet environments
  • Versatile for both freshwater and marine aquarium setups

Cons

  • Requires ongoing purchase of replacement cartridges
  • Limited capacity for custom filter media compared to canister filters
  • Not suitable for tanks larger than 70 litres

Setup, Compatibility & Care

Installation is straightforward: attach the unit to the aquarium glass using the adjustable clamp, extend the suction pipe to the desired depth, and ensure the filter is primed with water before switching on the power. For ongoing care, monitor the maintenance indicator; when the fleece becomes discolored or the flow rate visibly drops, it is time to rinse the foam or replace the carbon cartridge. Ensure the impeller area is kept free of debris by rinsing the impeller housing during monthly water changes to prevent motor strain.
