Product Information

Full details

The Oase BioSmart Replacement Foams are designed for pond owners using the BioSmart 5000, 7000, 8000, 14000, or 16000 filter systems who want to maintain efficient mechanical filtration. These coarse-grade blue sponges excel at trapping larger debris to keep pond water clear and healthy; however, they must be periodically replaced to prevent clogs and ensure consistent water flow throughout the filtration cycle.

FAQs

Can I use these foams in other filter brands?

No, these are specifically engineered for the dimensions and flow characteristics of the Oase BioSmart series.

How often should I replace these foams?

Replace them when they no longer retain their structure or fail to filter efficiently even after a thorough rinse in pond water.

Are these the same as the red or green foams?

No. Blue foams are coarse for large debris, whereas other colors typically feature finer pores for secondary mechanical or biological filtration.

Can I clean these in the washing machine?

Absolutely not. Chemical residues from detergents will be toxic to your fish and will destroy the biological balance.

Do these blue foams host beneficial bacteria?

While they are primarily for mechanical filtration, they will host some beneficial bacteria. This is why you must use pond water instead of tap water when cleaning them.

Troubleshooting

Filter output is lower than normal

The blue foams are likely saturated with debris. Remove and rinse them in a bucket of pond water.

Water appears cloudy despite new foams

Ensure the foams are seated correctly in the frame. If water bypasses the foam, debris will return to the pond.

Foams are crumbling during cleaning

This is a sign of material fatigue. Replace the foams to restore mechanical filtration efficiency.

Pros and Cons

Pros

  • Perfect fit for Oase BioSmart systems
  • Effective mechanical filtration of large debris
  • Easy to install and replace
  • Maintains optimal filter flow rates

Cons

  • Requires periodic replacement to maintain performance
  • Coarse foam does not remove fine particulate matter alone
  • Must be matched with biological media for complete filtration

Setup, Compatibility & Care

To install, power off your pond pump, open the BioSmart filter lid, and remove the old foams by lifting them from the internal brackets. Slide the new foams into the corresponding slots, ensuring they are seated snugly against the plastic frame to prevent water bypass.

Compatibility Checklist:

  • BioSmart 5000
  • BioSmart 7000
  • BioSmart 8000
  • BioSmart 14000
  • BioSmart 16000

Care Instructions: Periodically rinse the foams in a bucket of pond water during routine filter maintenance. Never wash these foams in tap water, as the chlorine will kill the beneficial bacteria living in the foam and disrupt your pond's ecosystem. Only replace the foams when the material begins to break down, crumble, or no longer recovers its shape after cleaning.
