Super idea, will see if i can find one - My theory is that the algea sticks to the small pores in the paper and closes it. IIRC seaweed/algea has very weak cell membranes since they aren't fighting gravity as much, and therefore "slimes out"
Fed all the goo to my worms, so i'll get the nutrients - eventually
just a thought i had bananas are ment to be full potassium if i feed the worms lots of bananas with other stuff to of course would this transfar into my vermicompost NPK ratio?
