During the rebranding sera reviews the functionality of products and optimizes product groups where necessary. The gravel cleaners available in the range so far have received a facelift. The Gravel Cleaner Round and Edge are now transparent, and the hose has also been extended to two meters.

At the same time, the Gravel Cleaner Nano is a new, particularly compact cleaner. It can be used to easily clean gravel in small aquariums as well as small areas of large aquariums and hard-to-reach areas. The highlight: the bypass opening can be finely adjusted to regulate the suction power and remove deposits from fine gravel types. Compaction of the substrate can thus be reliably prevented. The Suction Starter has been added to the range as the perfect complement to the gravel cleaners. The hand pump allows for easy siphoning of aquarium water and facilitates regular water changes.
