Subnautica 2 Salt — Where to Find & Farm It
How to find Salt in Subnautica 2: hand-pick it ~232m SE of the lifepod, or farm the white coral domes in the Dead Coral biome — plus uses and Sonic Resonator tips.

What is Salt used for?
Salt (sodium chloride / rock salt) is one of the most-used early resources in Subnautica 2, feeding nine blueprints — from Glass and Power Cells and Power Storage to a whole batch of food and water-purification items. In other words, you can't build the Tadpole or wire up base power without it, so it's worth stockpiling early.
Where to find Salt
① Early spot (hand-pickable)
Location: about 232m southeast of the lifepod at ~40m deep, right by the cave you visit to recover Chap's black box.
How to spot it: the ground is a rusty red with orange-brown algae, and the cave has a tall spire. Salt appears as small, pale-pink crystals on the walls and floor — pick it up by hand.
② Best farm: the Dead Coral biome (bulk)
Location: roughly 500m southeast of the lifepod, past the edge of the lava region.
Route: swim southeast about 350m until the lava biome's edge (the temperature rises), follow the cooler outer water around, and once the orange fog clears, turn east.
It's covered in white coral domes, and every dome has dozens of Salt deposits on its surface — just swim up and grab them. This is the fastest place to farm Salt.
How to harvest it efficiently
Salt can be picked up by hand with no tools at all. If you've built the Sonic Resonator, harvesting a node yields 8 Salt each, which speeds up stockpiling massively.
💡 Build a Scanner Station at your base to instantly track Salt (and any resource) within a 300m radius — it makes finding deposits far quicker.
What Salt is used for
| Category | Items that use Salt |
|---|---|
| Material | Glass (from Salt) |
| Power | Power Cell, Power Storage |
| Food / water | Isotonic Water, Nutrient Block, Halfmoon Jerky, Hoverthorn Souvlaki, Sugar of Saturn, Urchin Pudding |
The Power Cell in particular is central to vehicles and advanced gear, so Salt stays relevant across the whole progression.
A practical routine: on your first few dives, stock a stack of Salt from the early cave so you always have Glass and Power Cell materials on hand, then switch to the Dead Coral domes once base power needs it in bulk. Salt never expires, so over-farming it is rarely wasted — it is one of the few resources worth keeping a permanent locker stash of.
FAQ
Q: Where do I find Salt earliest?
A: A cave ~232m southeast of the lifepod at ~40m deep (near Chap's black box) — pale-pink crystals you pick up by hand.
Q: Where is the most Salt?
A: The Dead Coral biome ~500m southeast, where white coral domes are covered in Salt deposits — the highest density.
Q: Do I need a tool to harvest it?
A: No, hand-pick it. With a Sonic Resonator each node gives 8, which is faster.
Q: What is Salt mainly used for?
A: Glass, Power Cells/Power Storage, and several food and water items — needed for the Tadpole and base power.
Q: How do I find Salt faster?
A: Build a Scanner Station at your base to track Salt within 300m.
