ISTA FILTER WOOL

Description

Filter Wool (or Filter Floss) is great for removing fine particles from aquarium or pond water, helping to make it crystal clear. It catches the finest of particles that pass through the standard foam and other types of filter media.

Perfect for adding to a filter to remove suspended dirt particles and algae.

Filter wool is totally aquatic safe, and is not treated with any chemicals, so it will not harm your fish. This filter wool works on the principle of electrostatic attraction. This is where the waste particles from your aquarium or pond water will stick to the filter wool like a magnet.
