yeah. BL has some nice snails for grape caulerpa!
incidentally (ahem!)....why are you putting it to waste?
wash the caulerpa well, lightly wash with mild soap, rinse 3x. and then....put some vinegar or apple cider. Then...EAT! hehehehe....seafood salad from your refuge.
no kidding. it is crunchy, non-toxic, full of iodine and non-fattening (the seaweed turns brown as vinegar cooks it). why waste it?
