Hobby Aqualon Filter Wool, 500 g

Hobby Aqualon is a filter wool made of fibres which allows bacteria to easily colonise it as a filter mdeium, and also traps coarse dirt.

Place the desired amount of filter wool in the filter as the last filtering stage. Avoid leaving gaps between the inner wall and the filter. Replace the filter wool when the water flow rate is noticeably reduced. Although the filter wool can be rinsed and reused, replacing it completely is better as new filter wool filters much better.
