Summon a ocean spirit

First tie the seaweed around your wrist then start to go into meditative state feel the waves go back and forward then once you are ready put the hand with the seaweed bracelet on it in the water feel the energy of the ocean fusing with yours put your offering to Poseidon in the water (preferably wine) then chant "gods and goddesses of the 7 seas please send one of your children to me I offer this (name of offering) as a sign of peace please answer my prayer so mote it be" after this is done blow into the conch horn if you want to dispel the enchantment wait for the seaweed bracelet to shrivel up and then burn it
