Description
Nano = small but fine!
For an even higher filter performance, it can be used instead of the filter element with 3-fold fleece. Especially recommended for fish.
In the corner filter XL, the exchange with only one filter element results in multi-stage filtration.
Simply fill, rinse (because of possible abrasion caused by transport) and use instead of the filter element.
For filling with nano filter media (Bio-Filter Granules/Algae Stop/Active Carbon).
