OASE PondPads 20 l

Strong biological filtration depends on surface area. The OASE PondPads 20 L are high-performance biological filter media designed to support beneficial bacteria in pond filtration systems.

Supplied in a 20‑litre volume, they provide ample space for bacterial colonisation in medium to large pond setups.

What They Do

PondPads create a structured surface where nitrifying bacteria can grow. These bacteria are responsible for converting:

• Ammonia → Nitrite
• Nitrite → Nitrate

By supporting this natural process, PondPads help stabilise water quality and protect fish from harmful waste build‑up.

Why Use PondPads?

• High surface area for biological activity
• Durable, long‑lasting filter media
• Suitable for a wide range of pond filter systems
• Supplied in a convenient 20‑litre volume

They are ideal for upgrading biological capacity or replacing existing media in compatible filter chambers.

Where They Fit

Suitable for use in:

• Flow‑through filters
• Modular filtration systems
• Moving bed or static biological chambers (where specified)

Always ensure correct water flow and aeration for optimal bacterial performance.

Installation & Care

• Rinse lightly with pond water before first use
• Never wash with tap water, as chlorine can kill beneficial bacteria
• Inspect during routine maintenance and replace only if physically degraded

Strong biological filtration is what keeps a koi pond stable long term. PondPads help build that foundation.
