What water should you use on sea animal stings?

Answer 1

Seawater
Most marine animal venoms, like that of jellyfish or the barbs of poisonous fish, are alkaline in pH, so a mild acid like a vinegar solution has some neutralizing effect. Use copious amounts of it until the wound is clean, then apply an antibiotic ointment and sterile dressing.

Answer 2

clean fresh water should be used strate away to prevent infections
