Dennerle Nano Corner FilterPreview

Dennerle Nano Corner Filter

5.0 (3)

The movement of water in an aquarium should be slow but steady. With regard to the filter flow rate, this means that the golden rule is “as much as necessary, but as little as possible.” In aquaria containing plenty of plants and only a small number of shrimps, the plants will produce enough oxygen for the animals in the aquarium. The less plants and the more animals there are in an aquarium, the more additional oxygen should be introduced via movement of the water surface.
