## Overview

Sera Filter Wool is a high-capacity mechanical pre-filter made from durable, stable fibers that trap fine and coarse dirt particles without clumping. Designed for easy maintenance, it’s washable and reusable, compatible with all aquarium filter types for both fresh and saltwater tanks. When combined with biological filtration media, it ensures superior water clarity and a healthier aquatic environment.

## Description

Sera filter wool for the mechanical prefiltration consists of stable fibers that retain finer dirt particles for a longer time without sticking or collapsing. sera filter wool can be washed out several times. Suitable for all filters. We recommended sera siporax Professional for the biological filtration. sera siporax Professional is open pored and three dimensional – for lasting pollutant breakdown. sera filter media must be rinsed under warm water before using it for the first time. Tip: When used in combination with sera phosvec･clear and sera pond crystal, sera filter wool makes it easier to remove the bound substances.

Review: Fits all types of filters - Fits every type of filter, as it is loose wool. I used to buy a filter fleece mat, which I had to cut to fit my Seachem Tidal, so I always had a lot left. This wool can be put in easily and rinsed, so it can be used multiple times.
Review: Excellent - So much better than the filter floss I had been using! Will be coming back to this brand.
