If you've hit the mid-game wall in Subnautica 2 and your crafting progress has stalled, there's a good chance Strong Acid is the bottleneck. This material sits at the center of several advanced electronics recipes, and players who don't know where to look can spend a lot of time swimming in circles.

What Strong Acid actually is
The in-game description puts it plainly: Strong Acid is a concentrated acid used as a metal cleaner and catalyst for fabricating advanced electronics. That description sells it short. In practice, it unlocks some of the most important power and crafting items in the game, including the Power Cell and Advanced Battery that you'll need to keep your equipment running.
You can't find Strong Acid sitting in the world waiting to be picked up. It has to be crafted.
How to craft it at the Processor
The recipe is straightforward: 2 Necrolei Cysts processed at the Processor yields 1 Strong Acid. The Processor is the key station here, so make sure you have access to one before you start farming cysts.
The harder part is tracking down the Necrolei Cysts themselves. These grow from round, green plants that look like they're floating on their root systems. You'll find them clustered around green and purple anemones scattered across the ocean floor. For players still in the early game, the most reliable starting point is near the Old Habitat, which sits roughly 350 meters north of the Lifepod.
The anemone patches near the Old Habitat respawn over time, making them a solid early farming route if you need to stock up on Necrolei Cysts before pushing further into the map.
For a full breakdown of where to locate Necrolei Cysts efficiently and exactly how the crafting process works, the Subnautica 2 guide on finding Necrolei Cysts and crafting Strong Acid covers the route in detail.
Every recipe that requires Strong Acid
Here's the thing: once you start progressing, Strong Acid shows up in more recipes than most players expect. Stocking up early pays off.
The Power Cell is probably the most immediate priority for most players since it powers the Tadpole submersible. If you're also working on the battery crafting chain, the guide to crafting a Basic Battery is worth checking alongside this one, since you'll need batteries before you can build the Power Cell anyway.

Why this material matters for progression
Strong Acid sits at a specific chokepoint in Subnautica 2's progression. Players who skip farming it early tend to hit a hard stop when they need the Power Cell or Dedicated Core. The Entangled Power Cell in particular is a late-game requirement that demands a solid supply of Strong Acid on hand.
The survival games genre has always rewarded players who resource-plan ahead, and Subnautica 2 is no different. Knowing that Strong Acid feeds into five separate crafting trees means treating Necrolei Cyst farming as a recurring task, not a one-time errand.
For players looking to stay ahead of the resource curve, the full Subnautica 2 guides collection covers everything from salt farming to base building, so you're not caught short on materials when the deeper biomes open up.
