SPECIAL S(quid) is a well-known carp attractant that actually has nothing to do with squid. The smell is a bit like butyric acid, but it is made of another acid that has proven its attractiveness for years, is known for catching big fish and is a plus in winter.
If you can get over the smell, it is a must have.
Dosage:
Feed campaigns low dosage 5 - 20 grams/kg,
