Quick Answer
If your Water Filter displays Not Powered in Planet Zoo 2, check whether a power generator covers the facility. In the Nordic Fjords Career tutorial, placing the filter is only the first step. You must also configure the filtration network, set its salinity to Saltwater, and provide power.
Follow the active objective panel and check the filter's status again after placing a generator. Changing the salinity or connecting the filtration network does not, by itself, supply electricity.

Why the Water Filter Says Not Powered
Placing a Water Filter and supplying it with electricity are separate parts of the setup. In the Nordic Fjords Career tutorial, the filter can be placed successfully while its facility panel still displays a red Not Powered warning.
The panel may also show 0.0 m³/h for water supply while the filter's condition remains at 100%. These readings do not necessarily mean the facility is damaged. They can appear while the filtration setup is incomplete.
The tutorial's filtration objective involves several tasks:
- Place a Water Filter.
- Open the filtration-network editing interface.
- Set the salinity to Saltwater.
- Connect the filtration network to the aquarium.
- Place a power generator that covers the filtration facility.
If you have only placed the filter, continue through the remaining objectives before assuming something is broken.
Fix 1: Place a Power Generator Within Range
The first thing to check is whether the Water Filter is covered by a power source.
Step 1: Select a power generator
Open the facilities or construction menu and choose a power generator. In the Nordic Fjords tutorial, the generator objective appears after the filtration setup steps.
Step 2: Check the generator's coverage
Place the generator so the Water Filter falls within its operating radius. A generator can be present in the zoo without powering a facility outside its coverage.
If necessary, move the generator closer to the filter. Check the coverage indicator and the facility's status instead of relying only on how close the two buildings look.
Step 3: Check the Water Filter's status
After placing the generator, select the Water Filter and see whether the Not Powered warning has cleared.
If it remains, confirm that the generator's coverage includes the filter and that the placement action completed successfully. Then check the filtration network and the active objective before rebuilding the facility.
Fix 2: Connect the Filtration Network to the Aquarium
Power is only one part of aquarium filtration. The Water Filter also needs the correct filtration-network connection.
Step 1: Open the filtration-network editor
Select the Water Filter or the relevant pump, then choose Edit Filtration Network.
Step 2: Check the aquarium's connection point
Use the filtration-network interface to connect the filter network to the aquarium. Look for the connection node associated with the Aquarium Staff Gate rather than assuming that placing the filter beside the aquarium automatically links them.
Step 3: Verify the connection
Return to the Career objective panel and check whether the filtration-network task is complete. If the filter still displays Not Powered, check the generator's coverage separately.
A completed filtration connection does not guarantee that the filter has electricity. Network connectivity and power supply are separate requirements.
Fix 3: Set the Correct Salinity
The salinity setting is another requirement in the Nordic Fjords filtration tutorial.
Step 1: Open Edit Filtration Network
Select the Water Filter or pump and open Edit Filtration Network.
Step 2: Choose Saltwater
Change the salinity setting from Freshwater to Saltwater for this tutorial objective.
Step 3: Check the objective panel
Return to the objective panel and confirm that the salinity task is complete. If the filter still says Not Powered, do not keep switching salinity settings in an attempt to restore electricity. Check the generator's coverage instead.
Important: You can configure the salinity and filtration network while the filter displays Not Powered. Completing those settings does not replace the need for a power source.
What If the Warning Still Appears?
If the Water Filter continues to show Not Powered after you place a generator, check the setup in this order:
- Generator coverage: Confirm that the Water Filter is inside the generator's operating radius.
- Generator placement: Make sure the generator was placed successfully.
- Filtration network: Open the editor and confirm that the network is connected to the aquarium's connection point.
- Salinity: Check that Saltwater is selected when required by the current objective.
- Active objective: Read the Career task panel carefully to see which step remains incomplete.
- Facility status: Select the Water Filter again after making changes and check whether its warning or water-supply reading has changed.
Avoid rebuilding the Water Filter immediately. First establish whether the issue is power coverage, network configuration, or an unfinished objective.
If every visible requirement appears complete but the warning persists, save your progress and reload the scenario as a last-resort troubleshooting step. Reloading is not guaranteed to fix the issue, so try the checks above first.
What to Do After Power Is Connected
Once you have completed the filtration and power objectives, follow the next task shown in the Career panel.
In the Nordic Fjords tutorial covered here, the next step is to set the aquarium temperature to 28°C using the aquarium's Environment tab.
That temperature target belongs to this specific tutorial objective. Do not assume every aquarium or species in the game requires the same setting.
If you encounter a separate issue with the aquarium's staff gate, see our guide to fixing aquarium gate crashes in Planet Zoo 2.
Aquarium water temperature and animal habitat temperature are also different systems. For a separate habitat-temperature problem, see our guide to fixing animals that are too cold in Planet Zoo 2.
Frequently Asked Questions
Why does my Water Filter say Not Powered in Planet Zoo 2?
The filter may be outside a power generator's operating radius. In the Nordic Fjords Career tutorial, the warning can appear after the filter is placed but before the generator objective is completed.
Does connecting the aquarium power the Water Filter?
No. Connecting the filtration network to the aquarium and supplying electricity are separate requirements. Check both the network connection and generator coverage.
Should I set the filter to Saltwater before powering it?
The Nordic Fjords tutorial asks you to set the filtration network to Saltwater. You can configure that setting before power is connected, but it does not supply electricity to the filter.
Why is my Water Filter showing zero water supply?
A reading of 0.0 m³/h can appear while the setup is incomplete. Check the filter's power status and filtration-network connection before concluding that the facility is damaged.
What should I do if the warning remains after placing a generator?
Check the generator's operating radius, confirm that the filtration network is connected to the aquarium, and review the active objective. If everything appears correct, save and reload the scenario only after trying those checks.
Does every aquarium need to be set to 28°C?
Not necessarily. The 28°C target applies to the specific Nordic Fjords Career tutorial step described in this guide. Follow the requirements shown for your current aquarium and objective.
Final Checklist
If the Water Filter says Not Powered in Planet Zoo 2, work through these checks before rebuilding it:
- ☐ Place a power generator within the filter's operating radius.
- ☐ Open Edit Filtration Network and connect the network to the aquarium.
- ☐ Set the salinity to Saltwater when the objective requires it.
- ☐ Recheck the Water Filter's status and the active Career objective.
- ☐ Follow the next task once the filtration setup is complete.
The key is to treat power, filtration-network connections, and salinity as separate requirements. In the Nordic Fjords tutorial, placing the Water Filter alone does not finish the setup.
