Dont worry these thing are only little piece of shit and anyway i discovered a little zone without problems and close to the safe shallows and creepvine forest.
Bioreactor is good too and there are reginald,salt, and tube corals here.
Pratically is a infinite source of filtrered water and cured food.
I can build the water machine too because in the gellysrhoom caves there are some bases with a lot of loot.
So...yeah thats pretty good for a survival gampley!
