Amino Solutions ‘Black’ covers both Olfactory (fish’s sense of smell underwater) and Gustatory (fish’s sense of taste) senses within Carp. Amino Acids are the number one Chemo Attraction in Carp and other Cyprinids, so with this in mind, we have carefully formulated this liquid solution to be used as a Hook Bait Soak. It will improve any type of Boilie, Pop Up and Hookbait. Amino Solutions ‘Black’ differs from the clear version as it has added Amines and Ammonium compounds to raise the pH, you’ll notice the strong smell emitted from the bottle when opened, superb when used in conjunction with Fishy type flavors that are high in pH. Being totally water soluble, Amino Solutions can be used all year round. Amino Solutions ‘Black’ pH has been carefully increased to between 8.0 – 8.5pH, hence on the Alkaline side. Supplied in 100ml and 500ml bottles. Feedback we are having on this incredible liquid is nothing short of ‘wow’. Simply pour 5-10ml into a pot of hookbaits, shake well and leave to soak in over 24 – 48 hours, then repeat if necessary. Some crystallisation may occur whilst bottle is stood over a period of time, this is perfectly normal, simply shake well prior to use.
