So, you’ve got a hermit crab, or you’re thinking about getting one? Awesome! These little guys are fascinating pets. One of the most important things they need is saltwater, but not just any saltwater. It needs to be just right for them to thrive. Don’t worry, it’s easier than you think! This guide will walk you through everything you need to know about how to make saltwater for your hermit crab.

Why Saltwater is Important for Hermit Crabs
Hermit crabs need saltwater for a few key reasons:
- Drinking: Just like us, hermit crabs need to stay hydrated. They drink saltwater to get the fluids they need.
- Shell Water: Hermit crabs carry water in their shells to keep their gills moist. This is crucial for them to breathe properly. Saltwater is better than freshwater for this purpose.
- Humidity: Saltwater helps maintain the proper humidity levels in their enclosure. Proper humidity is necessary for breathing and molting!
What You’ll Need to Make Saltwater
Before you get started, gather these supplies:
- Dechlorinated Water: Tap water contains chlorine and chloramine, which are harmful to hermit crabs. Use dechlorinated tap water or bottled water.
- Hermit Crab Salt Mix: You can find this at most pet stores or online. It’s specifically formulated for hermit crabs and contains the right balance of minerals and salts. Avoid using table salt!
- Measuring Tools: You’ll need measuring spoons or cups to get the right ratio of salt mix to water.
- A Container: Use a clean bowl or container to mix the saltwater.
Step-by-Step Instructions
Ready to mix some saltwater? Here’s how:
- Dechlorinate the Water: If you’re using tap water, add a dechlorinating solution according to the product instructions. Let it sit for the recommended time.
- Measure the Water: Pour the appropriate amount of dechlorinated water into your mixing container.
- Add the Salt Mix: Carefully measure the hermit crab salt mix according to the instructions on the package. The ratio is usually around ½ cup of salt mix per gallon of water, but always double-check the specific instructions for your brand.
- Mix Thoroughly: Stir the mixture until the salt is completely dissolved. There should be no visible salt crystals at the bottom of the container.
- Test the Salinity (Optional but Recommended): Ideally, you’d use a hydrometer or refractometer to test the salinity of the water. The specific gravity should be between 1.018 and 1.023. This is about 25-30 ppt (parts per thousand). However, if you follow the instructions on the salt mix package, you can skip this step.
Important Tips for Success
- Always use dechlorinated water. Chlorine and chloramine are toxic to hermit crabs.
- Use a hermit crab-specific salt mix. Table salt doesn’t contain the necessary minerals and can harm your crabs.
- Follow the instructions on the salt mix package carefully. Different brands may have slightly different ratios.
- Don’t over-salt the water. Too much salt can be just as harmful as not enough.
- Store the saltwater in a clean, airtight container. This will help prevent contamination.
- Replace the saltwater regularly. Change the water in your hermit crab’s enclosure at least once a week, or more often if it becomes dirty.
How to Offer Saltwater to Your Hermit Crabs
Provide the saltwater in a shallow dish or sponge inside their enclosure. Make sure the dish is shallow enough that your hermit crabs can easily get in and out without drowning. A natural sea sponge soaked in saltwater works really well and is easier for them to drink from without risk of drowning!
Troubleshooting
- Cloudy Water: If the saltwater becomes cloudy, it’s likely contaminated. Discard it and make a fresh batch.
- Hermit Crabs Aren’t Using the Saltwater: Make sure the dish is easily accessible. You can also try misting their enclosure with saltwater to encourage them to use it.
FAQ Section
Can I use sea water for my hermit crabs?
It’s generally not recommended to use natural seawater because it can contain pollutants and harmful bacteria. Stick to using a hermit crab salt mix and dechlorinated water.
How often should I change the saltwater?
Change the saltwater at least once a week, or more often if it becomes dirty or cloudy.
What happens if my hermit crab drinks tap water?
Tap water contains chlorine and chloramine, which can be harmful to hermit crabs. If you suspect your hermit crab has ingested tap water, monitor it closely for any signs of distress and provide fresh, dechlorinated saltwater immediately.
Can I use table salt instead of a hermit crab salt mix?
No, you should never use table salt for hermit crabs. It doesn’t contain the necessary minerals and can be harmful.
How do I know if the salinity is correct?
The best way to know for sure is to use a hydrometer or refractometer to measure the specific gravity. It should be between 1.018 and 1.023.
Making saltwater for your hermit crab is a simple but crucial part of their care. By following these instructions and tips, you can ensure that your little friend has the healthy, happy life they deserve!
