Ironman verdict
Edible seaweed is a members item. Other players trade it, but an Ironman cannot use the Grand Exchange or trade, so you get your own. We list 9 monsters for it.
The lowest-level monster that drops it is Rock Crab (level 13), at 2/128, about one in 64 kills. The best rate is from Rock lobster (level 127): 10/128, 1–3 at a time. The 9 monsters we list with a combat level range from level 13 to 291.
Among the bosses we cover, Kraken drops it.
No recipe in our data uses it as a material. High Alchemy (55 Magic) turns one into 1 coins. Each cast uses a nature rune, 180 coins from a rune shop, and five fire runes that a fire staff replaces, so an alch loses about 179 coins; only alch it to clear space.
