For use exclusively with naco Corner Filter.
This additional protection for baby shrimp and fisg fry can easily be clipped onto the nano corner filter.
This prevents the youngsters from being sucked through the filter.
Pore size approx. 0.5 mm
This fits perfectly over the Nano-filter and is not flimsy or cheaply made. Looks better than just the "do it yourself" foam filter wrap you can make and place around your filter!
