Planet Zoo 2 How to Change Water Temperature
Water temperature in Planet Zoo 2 is controlled separately from the heaters you use around an animal habitat, which is why placing heaters directly beside or inside a body of water may leave its temperature unchanged. The correct control also depends on whether you are managing normal habitat water or an aquarium habitat.

How to Change Water Temperature in Planet Zoo 2
For water inside a standard animal habitat, select the water pump servicing that body of water and adjust its temperature setting. For aquarium habitats, select the aquarium's staff gate and open its water settings, where the temperature can be adjusted individually for that habitat.
After changing the setting, make sure the game is unpaused and allow simulation time to advance. The water may not immediately jump to the selected temperature the instant you move the slider.
Normal Habitat Water: Adjust the connected water pump.
Aquarium Habitat: Select the staff gate and change the water temperature there.
If Nothing Happens: Unpause the game and let simulation time advance.
How to Change Habitat Water Temperature
If an animal such as an otter is showing that its water is too hot or too cold, look at the utility equipment servicing the body of water rather than placing more heaters around the habitat.
Select the water pump connected to the habitat's water system and look for its adjustable temperature control. Move the setting toward the temperature required by the animals using the water, then let the simulation continue so the new value can take effect.
If the water is not properly connected to the required utility equipment, deal with that first. Our Planet Zoo 2 How to Connect Water Filter guide covers the water utility setup separately.
How to Change Aquarium Water Temperature
Aquarium habitats handle temperature differently. Instead of relying on the general habitat pump control, select the aquarium habitat itself through its staff gate.
Open the habitat's management tabs and find the water temperature slider. This lets you set the temperature specifically for that aquarium rather than changing every body of water connected to the surrounding utility network.
This distinction matters when you have several aquatic habitats with different species requirements. Treat temperature as an individual aquarium setting rather than trying to compensate with environmental heaters.
Water chemistry is another separate setting. If the issue is the animal's salinity requirement rather than temperature, our Planet Zoo 2 How to Change Water Salinity guide covers that system.
What to Do if Water Temperature Is Not Changing
If you have moved the temperature slider but the displayed water temperature still looks unchanged, first check whether the simulation is paused. Planet Zoo 2 needs simulation time to pass before some habitat conditions update.
This can also matter during tutorials. If the temperature control does not appear to be working or a required option has not appeared yet, advance the simulation briefly and check the habitat or pump again.
If that still does not solve it, confirm that you are adjusting the correct control for the type of water you are managing. A normal habitat body of water and an aquarium habitat do not necessarily expose the temperature option in the same place.
For ordinary habitat water, return to the pump. For an aquarium, return to the staff gate and its habitat settings. This is a better troubleshooting step than repeatedly adding heaters when the problem is actually the water system's own temperature setting.
Why Habitat Heaters Do Not Change Water Temperature
Habitat heaters are not the control used to set the water temperature itself. They can help manage environmental conditions around an enclosure, but placing them in or around a lake does not replace the dedicated water temperature setting.
That is why an animal can still show its water sitting at ambient temperature even when heaters are nearby. The water system needs to be adjusted directly through the pump or, in an aquarium habitat, through the aquarium's own water controls.
Once the correct setting is selected and simulation time is running, monitor the animal's water requirement rather than the surrounding air temperature. That confirms whether you changed the condition that was actually causing the welfare warning.
