Hydor Koralia nano 900 is a new innovative stream and circulation pump for aquariums. The exklusive Hydor design and technology guarantee a continuous and powerful water flow which can be directed freely thanks to the special sphere shaped connection to the exclusive combination suction cup + magnet support.

I use it in my 360l malawi aquarium where the vallisneria started to hinder the circulation in the aquarium.
The Koralia nano 900 is easy to put together and very quiet. For an aquarium that is 130cm wide it provides a gentle flow that the fish like.
