Hydroflux Reservoirs Mod expands fluid and item storage by adding multi-tiered tanks and vaults that morph into any shape you build. The mod works with liquids and items from popular tech mods like Create and Mekanism, giving you complete freedom to store resources in tight spaces. You can build custom storage shapes to power machines, fit engines inside moving contraptions, and keep your factory organized without wasting room.
