Chihiros Sivellin PRO-Brush Hard 15cm

The rigid metal bristles provide stronger mechanical cleaning than the flexible rubber bristles of the standard PRO-Brush. They are intended for durable, textured hardscape where soft brushes cannot remove established algae effectively.

The compact 15 cm format is particularly suitable for close-range cleaning, nano aquariums and removable hardscape elements. For deeper aquariums, the separate 23 cm version offers additional reach.
