Sera Gravel Cleaner Nano

Larger amounts of detritus in the aquarium are not only unsightly but can also affect water quality. The coarser the gravel, the more detritus accumulates in the gaps. Food disappears into the substrate before it can be eaten, and animal waste as well as dead plant material can collect and may not reach the filter. With the Gravel Cleaner Nano, small and hard-to-reach areas can be gently cleaned, allowing sufficient beneficial bacteria to remain in and on the substrate. Particularly fine gravel and sand can also be easily loosened and cleaned thanks to the bypass opening. This reliably prevents compaction of the substrate.
