Dennerle Nano Gravel Cleaner

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. Easy to assemble and clean. If you have many algae or relatively big organic waist. then you need to remember that basket/protector has small grids and can be blocked up. Recommend to buy!

Its perfect for small fish tanks. Also it will pulls out the water very slowly so you have the time to clean everything inside.

Its nice because its small so its perfect for a nano aquarium. You can reach places better and you can take your time because the water will get sucked in really slowly. But on the other hand I think sometimes it would be better to have a stronger flow because it doesnt get all the dirt off the substrate. So it depends on what you want to do with it I guess. I will still use my other cleaner as well.
