Product Information

Full details

Designed for pond owners using Oase BioTec 5.1 or 10.1 filtration systems, these replacement filter foams offer an efficient and cost-effective method to maintain pond water clarity. These medium-grade, corrugated foams excel at trapping suspended algae and organic debris to keep your aquatic environment healthy. However, as aftermarket replacements, users should ensure they are properly seated on the existing foam handles during installation to maintain optimal flow rates.

FAQs

Are these foams compatible with the Oase BioTec 10.1?

Yes, these replacement foams are designed to be fully compatible with both the Oase BioTec 5.1 and 10.1 filter systems.

How often should I replace these filters?

Replacement frequency depends on your pond's bioload, but generally, they should be replaced when they no longer return to their original shape or become too clogged to rinse effectively.

Do I need to rinse them before the first use?

It is good practice to give them a quick rinse in a bucket of fresh or pond water to remove any manufacturing dust before placing them into your filter.

Why are the edges of the foam corrugated?

The corrugated design increases the surface area, which helps trap more debris and provides more space for beneficial bacteria to grow.

Is this a two-pack?

Yes, the product is sold as a twin pack containing two foams.

Troubleshooting

Water flow is reduced after installation

Check to ensure the foam is seated correctly on the handle and not pinched against the side of the filter box.

Foam keeps popping off the handle

Ensure the pre-cut slit is fully engaged with the foam handle clip; if the handle is damaged, the clip may need replacement.

Pros and Cons

Pros

  • Significantly more affordable than original manufacturer parts
  • Pre-cut design simplifies the installation process
  • Durable medium-grade material holds up well against pond water conditions
  • Effectively traps common pond pollutants and algae
  • Twin pack provides a complete set for routine maintenance

Cons

  • Not an official Oase branded product
  • Requires manual handling during the replacement process
  • Performance depends on regular cleaning cycles

Setup, Compatibility & Care

To install, simply remove your old, degraded foams from the BioTec handles and discard them. Slide the new Pisces foam onto the handle, ensuring the pre-cut slit aligns correctly with the mounting bracket.

Maintenance Tips:

  1. Inspect filter foams every 2-4 weeks, depending on your pond's organic load.
  2. Gently squeeze the foams to clear trapped debris.
  3. Replace the foams entirely when the material begins to lose its structural integrity or can no longer be cleaned to a functional state. Always replace in pairs to maintain balanced water distribution within the filter chamber.
