Seaweed

Detailed

Typical

Release

18 March 2002 (Update)

Seaweed is a key ingredient in making molten glass, although it must first be cooked into soda ash if the player is not using the Lunar spell Superglass Make. Using seaweed on a range or fire will cook it into the soda ash, giving 1 Cooking experience per seaweed cooked. If a dwarven army axe is either wielded or in the player's inventory, cooking seaweed instead yields 3 experience points each. A pestle and mortar can be used on seaweed to create ground seaweed, which has no use aside from making fish food, and awards the player with 1 Cooking experience.

20 seaweed are a possible prize from Treasure Hunter. When choosing the option to convert this prize to coins, players receive 500 coins during the Double Cash period, implying that normally they would be converted to 250 coins, which is 310 less than selling them on the Grand Exchange.

Cooking seaweed into soda ash yields a profit of −19 coins each.

Obtaining seaweed

For free

Seaweed can be found in several places, along shorelines and sometimes rivers. Some locations are:

Karamja. The western and eastern shores of the central part of the island have seaweed, as does the northern shore of east Karamja (south of Musa Point). North bank of the river that flows through Shilo Village has 3 seaweed.
North eastern Entrana. 15 total: 9 east of the chicken pen, 6 north of the Law Altar. (Weapons and armour cannot be taken to Entrana.)
Northern Fremennik Province, in the Rock Crab area north-west of the entrance to Keldagrim. This area has 9 seaweed spawns and is recommended. With a full inventory of seaweed nets, one can make a rather large profit. The area is accessible by using the cave to go to Keldagrim and using the bank there, or by using Fairy rings allows fairly quick access between this area (coordinate DKS) and the bank at Zanaris. (Players must complete at least part of the quest A Fairy Tale Part II to have full access to the fairy rings.) Players can use the Rellekka lodestone to teleport fairly close.
North-eastern corner in Piscatoris Fishing Colony. There are two nets with seaweed.
Although not technically free, the purchase price in the section below is so low that it might as well be free, considering the Grand Exchange price.
Northern Fremennik Province. Log onto a high volume world and bring 27 seaweed nets to Northern Fremennik Province to the Rock Crab area north-west of the entrance to Keldagrim. In about 15 minutes, you can get 27 full (10) seaweed nets. Potentially dangerous due to level 102 Rock Crabs. Use Fairy Ring DKS or AJR or Lodestone teleport.

As drops

Seaweed is available as a drop from monsters. For example, Rock Crabs drop either seaweed or noted seaweed.

By purchasing

Seaweed can be bought from Arhein in Catherby for 2 coins each. Arhein does not stock the seaweed in his shop; instead, players must choose to talk to Arhein and use the prompt: "Can I buy some seaweed?". Arhein will only sell 80 seaweed per day. He sells the seaweed noted. There is both a range and a bank near Arhein, which is quite convenient for rapidly turning the seaweed into Soda ash.

Additionally, players may be able to purchase seaweed on the Grand Exchange, or by trading with another player.

By fishing

Players may acquire seaweed by catching it in a big net while fishing at a net fishing spot. This will also give 1 experience.

The Superglass Make lunar spell allows players to use either seaweed, OR soda ash to make molten glass. So if the spell is used, there is no need to burn the seaweed into soda ash.

Ten seaweed can be stored in a Seaweed net.

Making Money Using Seaweed

Seaweed is very commonly used for making money. Examples would include:

Buying 80 Seaweed a day at Catherby from Arhein for 2gp each and selling them in the G.E. for a total profit of 2,080. This will usually sell quickly on the Grand Exchange.

Buying Seaweed from the Grand Exchange, cooking it into soda ash and selling it yields a profit of −19 coins each.

Catching Seaweed using a Big fishing net in certain fishing spots around RuneScape that are close to a bank, such as Catherby.
After completing Deadliest Catch, Fisherman Jones will reward you with several deposit chests; one of which is located south of the Karamja lodestone. If walking isn't an issue this chest can be used to collect seaweed for an indefinite period of time.
