Liquid Tank

Liquid Tank is a large-capacity fluid storage block that holds and redistributes liquids in multiple directions. It functions similarly to the Liquid Router in output behavior — it can push fluid out toward all adjacent tiles rather than forcing a single-direction flow — while providing a substantial buffer for mid- to late-game fluid logistics. Liquid Tank appears among the game's storage blocks and is used to accumulate production from pumps or to stage fluids for processing and forwarding through your network.

Liquid Tank stores a large amount of liquid: 2700 units. Use it to decouple production from consumption (for example, to keep boilers or refineries fed during peak demand) or to create a reservoir that supplies multiple consumers simultaneously. Because it distributes fluid outward like a router, a single tank can feed several machines or lines without additional routing logic, reducing the need for many small tanks or complex duct layouts.

Placement and environmental interactions are important for reliable operation. Liquid Tank can be placed entirely in Deep Water provided it still has adjacency to land; it must be adjacent to at least one land tile to function when submerged. When placed in certain hazardous or special liquid floor tiles — specifically Slag, Tar (on floor), Arkycite, or Cryofluid (on floor) — the tank requires either an internal tile of shallow water or a non-empty non-liquid tile inside its area, or at least one non-corner adjacent shallow water or non-liquid tile around it. These placement conditions prevent tanks from being placed completely surrounded by those fluid terrains.

Two Liquid Tanks placed next to each other can act as a long bridge for fluids, allowing a continuous connection across gaps: two adjacent tanks can span up to six tiles in length. This is particularly useful on maps where the Phase Conduit is not available or when you need to carry large volumes across water or impassable terrain without building expensive conduit bridges.

Practical usage notes:

• Place Liquid Tanks near pumps to smooth out intermittent extraction or to store surplus from oil/slag/cryofluid sources. Tanks absorb production spikes and prevent pump stalling when consumers temporarily exceed supply.
• Use a tank as a distribution hub: because it outputs in all directions like a Liquid Router, a single tank can supply several machines around it without extra routing blocks.
• Combine tanks in series or parallel to increase total capacity or to bridge longer gaps; two adjacent tanks can be used to span long distances when paired with pumps or transport ducts.
• Respect placement rules on maps with Deep Water or special fluid floor tiles; ensure a legal adjacency or internal tile condition before construction to avoid invalid placement.
• For high-temperature or reactive fluids (lava, tar, etc.), place tanks at safe distances from vulnerable structures and consider the fluid properties (viscosity, heat capacity, flammability) when designing processing chains, since different fluids affect pumping behavior and machine performance.
