Cleaning Brush Set – 3 Piece

This three-piece cleaning brush set covers the full range of aquarium pipework diameters found in modern filtration systems. The small brush handles CO2 diffuser bodies, lily pipe openings, and narrow spray bar holes. The medium brush suits standard filter intake and outlet pipes (12–16mm). The large brush manages filter return pipes and wide canister hoses (20–25mm).

All three brushes share the same flexible wire core construction, allowing them to navigate mild curves in pipe runs without kinking or losing bristle contact with the inner surface. The nylon bristles are firm enough to dislodge established biofilm but safe for the plastic and glass pipes found in most filtration systems.

Keeping the set together and using the right size for each task produces thorough cleaning results in less time than using a single compromised brush across all applications.
