How To Use the Pump Take the pump and container, add the Pellets any type of pellet will do, but Expander pellet will make the best hook bait. ..... You Next Add water so it covers the bait, you can add flavours if you wish, i find by using a oil based flavour and leaving the pellet in a plastic bag over night makes the pellet rubbery and a perfect hook bait, you will see the pellets start to foam this is caused by the air being drawn out of the pellets and replaced by the liquid.                       .........................                     ..... Leave the pellets in the container for a few minutes, remove them and you have perfect sinking pellets, if you have used an oil based flavour and wish them to be used as hook baits i put them into a plastic bag and allow to soak overnight. please note i use the Expander type pellet for hook baits.
