Fluid Tick Delay

Fluid Tick Delay is a Minecraft mod that gives you fine-grained control over how quickly fluids flow and spread in your world, on a per-biome basis. This lets you tweak how water and lava behave in different environments. For example, making water flow more sluggish in deserts but lightning-fast in plains. This mod handles only the tick rate (flowing speed) of fluids and does not alter fluid physics or interactions beyond timing. This should also work on modded fluids

All settings are easily configurable through a simple JSON file, allowing both modpack developers and adventurous players to tune fluid behavior for unique gameplay or performance optimization.

Inworld Examples

Fast flowing water in Plains

Fast flowing lava in Forest, slower flowing water

Configuration

Edit the fluidtickdelay_config.json found in your config folder. Each biome entry controls the tick delay for specific fluids in that biome (lower values = faster flow).

Example `fluidtickdelay_config.json`

{
  "minecraft:desert": {
    "minecraft:water": 15,
    "minecraft:lava": 5
  },
  "minecraft:plains": {
    "minecraft:water": 1,
    "minecraft:lava": 10
  }
}

In this sample:

Water flows much slower in deserts (tick delay of 5) versus plains (tick delay of 1).
Lava flows are also distinct between biomes.

Note: If a fluid or biome is missing from the config, its tick delay falls back to Minecraft’s default behavior.
