Mild Acid
HarvestMaterialOverview
Mild Acid is a crafting material in Subnautica 2, obtained by harvesting from the environment. Required in 4 crafting recipes: Echo Location, Biolab, Processor, and Biolab. Its presence in multiple recipes makes it a recurring material demand throughout the early and mid game. Intermediate materials like Mild Acid create the logistical challenge that defines Subnautica 2's survival crafting. Unlike raw resources found in the world, materials must be intentionally produced, adding a planning layer between exploration and equipment readiness.

How to Obtain
Tips & Strategy
Required for crafting Echo Location, Biolab, Processor — gather extra during exploration to avoid dedicated farming trips later.
Store Mild Acid in a dedicated Wall Locker near your Fabricator — with 4 recipes requiring it, quick access prevents workflow interruption during extended crafting sessions.
Used across multiple crafting stations (Habitat Builder, Modification Station) — distribute your Mild Acid supply between stations or keep it in a central storage area.
Explore different biomes systematically to discover all Mild Acid sources — harvested organic resources often appear near specific flora or fauna, and identifying these associations makes future gathering predictable.
When gathering Mild Acid for Echo Location, also collect Quartz and Atacamite on the same trip — completing all recipe requirements in one expedition saves significant travel time.
