Very effective filter

So I bought the largest of the three filters (2042) and must say that this is very effective.
I run the filter on a breeding tank (Cube35) for shrimps and prawns have therefore made sure i have in the intake manifold just a piece of a filter mat (fine) used appropriately.
Furthermore, I have modified the filter in which I have both sides of the inside equipped with the same filter media.

Assembly from left to right:
Filter Sponge Cartridge blue / cut to size fine white fleece / activated carbon cartridge --- activated carbon cartridge / cut to size fine white fabric / sponge filter cartridge blue

Thus, the filter works very effectively, the fleece or the cartridges are cleaned every 4 weeks under running water, not replaced!

+ Small filter
+ Easy operation
+ Easy to clean
+ Ideal for small (shrimp) basin
+ Very quiet

So far, nothing negative.
