Power Expander pellets are sinking pellets that allow you to create perfectly soft hook pellets without the need for a pump. The process is extremely simple: pour the desired amount of pellets into an airtight container and cover them completely with water. Then leave them to rest overnight in the refrigerator – the pellets will reach the perfect soft texture! After preparation, you can fully customise your expanders by adding fluo additives or an Amino Booster.
