Within an aquarium that is supplied with many plants, unattractive detritus can occur on the substrate or the groundcover plants due to dead plant parts, feces of the animals and other organic residues. In combination with feed residues and other organic waste inside the aquarium, a nutrient surplus and, thus, problems with accompanying fauna or algae are possible. To prevent this effect from happening, a Gravel Cleaner can be a practical tool.

Especially in small aquariums it is hard to reach the detritus in the different places between stones and underneath plants. The NANO Gravel Cleaner by Dennerle provides remedy for this problem. With the practical included pump, the suction is easily started. The slim suction pipe facilitates the removal of the dirt in places that are hard to reach. Even the water change is easier with the included hose holder and flow regulator.


  • Removes the detritus off the substrate
  • Easy to handle due to integrated pump
  • Helps with the water removal by suction
  • Regulation of flow possible
  • Includes a hose holder
  • For aquariums from 10 to 40 L

Must Have

I am using it to clean 45cm tank. Cleaner do its work. Suction tube has relatively wide diameter but hose diameter is small so you have enough time to clear whole aquarium. (read more)
