Filter Socks and Fleece Rolls
Help and advice on shopping for: Filter Socks and Fleece Rolls
What is a filter sock?
This mechanical filter media fits over the drain pipe in your aquarium and traps waste from the water before it reaches the sump. They improve water clarity by removing any uneaten food, debris, and waste, reducing a build up and keeping maintenance simple as they are easy to clean or replace.
What are fleece rolls?
These rolls are disposable mechanical media used in automatic roller filters to remove waste and debris from the aquarium water. The fleece traps any particles, and the roller automatically advances fresh media, for continuous filtration with minimal maintenance. In our range we carry a selection of high quality replacement rolls for many different roller filters.

Frequently Asked Questions
How do I clean a filter sock?
Cleaning these socks is simple. Just remove it from your filter and rinse away any trapped debris in clean water. Allow to dry completely before reusing to maintain effective mechanical filtration. If using a washing machine, make sure never to use any detergents or fabric softeners due to harmful residue.
Can I reuse fleece rolls?
Fleece filter rolls are designed to be disposable and should be replaced once they are clogged with debris. Reusing fleece rolls will significantly reduce performance and allow waste back into the system.
How often should I replace a filter sock or fleece roll?
This depends on your tank size and stocking levels, as every aquarium produces a different amount of debris. Socks are typically only replaced when the material becomes worn or damaged, or won't come clean anymore. Fleece rolls are replaced more frequently, whenever the roll is used up.
What is filter wool?
Filter wool is a fine mechanical filtration media that traps particles of debris, improving water clarity. Wool is commonly used as the final stage of the filtering process before the water is returned to the aquarium.
