Features

Tiered Tank System

7 tiers of tanks with increasing capacity:

Tier	Capacity Multiplier	Notes
Base	1x
Stone	2x
Copper	4x
Iron	8x
Gold	16x
Diamond	32x
Netherite	64x	Fireproof

Base capacity is 32 buckets by default (configurable). Each tank's capacity = base × multiplier.

Connected Storage

• Place tanks adjacent to each other to form a connected group
• Connected tanks combine their capacity into a single fluid pool
• Visual connection indicators show linked sides
• Internal borders between connected tanks become invisible

Fluid Interaction

• Use buckets or bottles directly on tanks to fill/drain
• Supports any fluid type (water, lava, etc.)
• Breaking a tank drops it with its proportional share of stored fluid
• Upgrading a tank tier via crafting preserves the fluid contents

Visual

• Transparent block with real-time fluid level rendering
• Light passes through tanks
• Tier-specific frame and side textures

Requirements

• Minecraft 1.21.8 / 1.21.11
• Fabric Loader >= 0.17.2
• Fabric API
• Fabric Language Kotlin

Optional Dependencies

• Jade - Fluid info tooltip on tanks
• ModMenu + YACL - In-game configuration screen
