Fluval U2 Underwater Filter Foam Pad

This genuine Fluval Bio-Foam pad captures large particles and debris for effective mechanical filtration in its matching Fluval U filter.

Fluval U2 Underwater Filter Foam Pad

Specifically designed for the Fluval U2 filter, the U2 Bio-Foam Pad captures large particles and debris for effective mechanical filtration.

The Fluval U2 Underwater Filter Foam Pad handles mechanical filtration, trapping debris before it reaches the biological stage — see our guide to choosing filter media for how the three media types work together.

Specifications

Item: A486

Type: Bio-Foam mechanical filter pad

Fits: Fluval U2 Underwater Filter — cut to the chamber so debris cannot pass round it

Supplied: 2-pack

Use in: freshwater, saltwater or reptile setups

Setup & Use

Slide the pad into the U2's filter chamber. It is the mechanical stage — it catches the large particles and debris before they reach anything else.

Rinse it in old tank water when the flow drops, not under the tap, and replace it when it no longer springs back. A foam that has gone hard has stopped filtering and started restricting.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months' remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.

Filter media and substrates carry no manufacturing or expiry date — their working life begins on first contact with water, not on the shelf.

Returns & Replacement

Returns are accepted within 7 days of delivery, provided the item is unused and in its original packaging. Manufacturer-sealed items cannot be returned once the seal is broken, and sale-priced items are not refundable.
