Herons,cormorants,seagulls and other flying predators will be kept away from your fish with this 1mm thick long lasting and rot proof black netting.
When fitted it is very effective and being black does not look obvious to the eye.
It is knotted netting so therefore strong enough to keep cats etc away from your fish but not strong enough to stop cricket balls !
ALL MY NETTING IS PROFESSIONAL GRADE KNOTTED NET-NOT INFERIOR WOVEN OR EXTRUDED PLASTIC !!!
