1. Dennerle Nano corner filter
The Nano Corner Filter is powerful with a pump performance of 150 l/h. The pump operates so smoothly and quietly that it is practically inaudible. The energy consumption is also impressive: only 2 watts – which helps conserve natural resources.
The water flow can be adjusted continuously, and the water stream can be directed in any desired direction thanks to the filter outlet that can be rotated 90 degrees. The filter features a nozzle pipe with an integrated cleaning slider as well as a mini brush for easy cleaning of the nozzle openings. Due to its narrow intake openings and a very fine-pored pre-filter sponge, the Nano Corner Filter is also safe for young shrimp.
Cleaning the filter element is very easy: simply grasp the filter at the outlet pipe and pull it forward, then remove the filter element. It is best to wash the filter element in a clean bucket with aquarium water to avoid harming the important filter bacteria.
Pro
- Works quietly
- Works reliably
- Low power consumption

3. Dennerle Osmosis Professional 190
The white hose delivers soft, high-purity reverse osmosis water. The hardened, contaminated residual water from the blue hose is directed into the drain. The simple production of high-purity, very soft water is the ideal basis for establishing species-specific water values for freshwater and saltwater aquariums. It features a modern polyamide/polysulfone membrane. An activated carbon filter protects against chlorine, while a fine filter protects against suspended particles. The increased lifespan of the membrane and the high flow rate are due to a flush valve that removes performance-reducing deposits from the membrane. This system removes hardness, salts, pollutants, bacteria, and viruses.

- Easy to connect
- Easy to operate
Contra
- Lots of residual water (1:4)
- No indication of important osmosis water additives
