Sera Nano Gravel Cleaner

- Thoroughly and reliably removes sludge deposits from gravel. - Ideal for cleaning small aquariums and hard-to-reach areas. - Suitable for all types of gravel. - Can also be used in sand due to the adjustable bypass. - Includes a 2m long transparent hose for immediate use. Large amounts of sludge are not only unsightly in an aquarium, but they can also affect water quality. Excess food sinks to the bottom, along with animal waste and decaying plant matter, which may not reach the filter. The coarser the gravel, the more sludge accumulates in the gaps. With the Sera Gravel Cleaner Nano, small and challenging areas can be cleaned gently, allowing sufficient beneficial bacteria to remain on the substrate and base. Even particularly fine gravel and sand are easily disconnected and cleaned thanks to the bypass. This effectively prevents substrate clogging.
