Product Information
Full details
The Oase BioMaster Pre-Filter Tube is an essential component designed for owners of Oase BioMaster 600 and 850 external aquarium filters, including Thermo variants. It serves as a critical bridge in the filtration process, ensuring that debris is captured effectively before it reaches the main biological media, thereby maintaining long-term water clarity. While this part is highly durable, it requires regular inspection to ensure that clogging does not restrict overall water flow through your system.

FAQs
Is this tube compatible with the BioMaster 250 or 350?

Why is my filter making a rattling noise?

Setup, Compatibility & Care
Installation is straightforward: disconnect the power, close the filter valves, and remove the pre-filter module from the top of the BioMaster canister. Remove the old tube and slide the new unit into the designated housing. Ensure that all O-rings remain seated correctly during reassembly to avoid leaks. To care for this part, rinse it under lukewarm water (ideally tank water to preserve beneficial bacteria) every time you perform a filter cleaning. Avoid using detergents or chemical cleaners, as these can leave residues that are harmful to your aquarium inhabitants.
