Seaweed detail.png

Seaweed is an item dropped by creatures near water like Rock Crabs. It can be used with a fishbowl that is full of water so that you can catch a fish in the Catherby aquarium. Seaweed can be used for normal compost.

Seaweed can be cooked on a range or fire to create soda ash, an ingredient for molten glass, but this awards no xp. Seaweed may also be used in place of soda ash in the super glass make lunar spell, skipping the need to to convert it to soda ash.

Collecting 5 seaweed from anywhere on Karamja is an easy task of the Karamja Diary.
