Hobby Brush Set

The Hobby Brush Set is a pair of aquarium cleaning brushes for removing algae, slime and dirt from filter parts and CO2 equipment. Each brush has a stainless steel stem, so it will not rust, and stiff nylon bristles that shift even stubborn deposits from awkward, hard-to-reach places. One brush is very slim for narrow tubes, the other much wider for larger pipes and fittings, and both have the same long overall length, so you can work deep inside hoses and connectors.

Key features of the Hobby Brush Set

• Stainless steel stems
• Stiff nylon bristles
• Slim and wide brush
• 230 mm total length
• For filter and CO2 parts

Which brush for which job

The slim 3.5 mm brush is the one for narrow parts such as CO2 diffuser stems, bubble counters, check valves and the small tubes of glass inflow and outflow pipes. The 24 mm brush suits wider parts, including filter intake pipes, hose connectors, spray bars and pump housings. Scrub parts in a bucket of old tank water rather than with detergent, which can leave residues that harm fish. For heavy limescale, soak the part in a mild vinegar or citric acid solution first, then brush and rinse thoroughly before refitting. Rinse and dry the brushes after use.

Good to know

Clean filter parts without soap or detergent, and rinse them well before putting them back.
