Filter Floss Pad (white) for Sera Fil 250 / Fil 250 + UV / Fil 400 + UV – 2 pcs

These white filter floss pads are made for use with Sera Fil 250, Fil 250 + UV and Fil 400 + UV aquarium filters. Supplied as a pack of two, the non-woven pads trap fine particulate debris and suspended solids before they reach biological or chemical filter media. Installing fresh floss pads during routine maintenance helps preserve water clarity and reduces mechanical load on downstream media, supporting steadier filtration performance.

Advantages

The pads are constructed from dense, non-woven synthetic fibres that capture small particles while allowing adequate water flow. Their white colour makes it easy to see accumulated dirt and determine when replacement is needed. Sold as a pair, the pads provide immediate spare capacity for regular maintenance intervals and are compatible with the specified sera filter models.

Suitable for

• Mechanical filtration in freshwater aquariums using Sera Fil 250, Fil 250 + UV or Fil 400 + UV
• Routine maintenance and replacement of worn or clogged mechanical filter media
• Pre-filtration ahead of biological or chemical media to extend media life
• Removing suspended solids after water changes or during periods of increased debris

When it may not be suitable

These floss pads are designed specifically for mechanical filtration and will not provide biological or chemical filtration on their own. They are sized for the specified Sera filter models and may not fit other brands or filter types. If your goal is to control dissolved substances (e.g., tannins, medications) you will need appropriate chemical media in addition to these pads.

Key specifications

• Material: non-woven synthetic filter floss
• Colour: white
• Pack quantity: 2 pads per pack
• Function: mechanical particle capture / pre-filtration

How to use

Open the pack and insert a floss pad into the mechanical filtration compartment of the compatible Sera filter according to the filter manufacturer’s instructions. Position the pad so water flows through the pad before reaching biological or chemical media. Inspect the pad regularly; replace it when it shows significant discoloration or when water flow is noticeably reduced. Dispose of used pads and install a fresh pad during routine filter maintenance to maintain optimal filtration performance.

What to consider before purchase

• Compatibility with Sera Fil 250, Fil 250 + UV and Fil 400 + UV models
• These pads perform mechanical filtration only and do not replace biological or chemical media
• Frequency of replacement depends on stocking levels, feeding, and debris load

Usage recommendations

For stable aquarium water quality, pair these pads with appropriately maintained biological media and replace mechanical pads as part of a regular maintenance schedule. Consider checking the pad after water changes or heavy feeding to ensure it is not clogged, and keep spare packs on hand to avoid lapses in mechanical filtration.
