You’ve set up a cozy home for your axolotl, but now the water looks cloudy. It’s frustrating, right? Don’t worry—you’re not alone.
Cloudy water is a common issue for axolotl owners, and fixing it isn’t as tricky as it seems.
With a little care and the right steps, you can keep your axolotl’s tank crystal clear and safe.
What Causes Cloudy Water in Axolotl Tanks?

Before you tackle the problem, it helps to know why the water gets cloudy. The main culprits are poor filtration, overfeeding, and bacteria blooms. Each of these has its own unique signs and solutions.
While captive axolotls can live up to 15 years, those in the wild typically only survive for about 5-6 years, primarily due to predation and habitat degradation.
Poor Filtration
Axolotls produce a lot of waste, so a good filter is essential. Without proper filtration, waste and debris build up quickly, making the water murky. Using the wrong type of filter or not cleaning it often enough is a common mistake.
- Choose a sponge filter or a gentle canister filter. Axolotls prefer calm water, so avoid filters with strong currents.
- Clean the filter regularly to remove the gunk that can clog it. Aim for every two weeks, but adjust based on how much waste your axolotl produces.
Overfeeding
It’s tempting to spoil your axolotl with treats, but too much food can sink to the bottom and decay. Leftover food releases ammonia, which clouds the water and harms your pet.
Without a filter, you must do a 20% axolotl water change daily. Do not completely change the water; this will drastically alter the water chemistry and cause stress..
- Feed your axolotl just enough to eat within two minutes.
- Remove uneaten food within 15 minutes to prevent buildup.
Bacteria Blooms
Cloudy water often means a bacteria bloom is happening. This occurs when beneficial bacteria are still stabilizing in the tank or when there’s an imbalance. It’s common in new tanks or after a major cleaning.
- Be patient if your tank is new. The water should clear up in a few days as the bacteria settle.
- Avoid over-cleaning, which can disrupt the bacteria that help break down waste.
Steps to Prevent Cloudy Water in Axolotl Tanks
Let’s get into the practical steps you can take to keep your axolotl’s water clear. It’s all about regular care and smart choices.
Set Up a Proper Filtration System
The right filter is your first line of defense. Look for one that balances efficiency with gentle water flow. Axolotls are sensitive to currents, so a filter designed for calm water is ideal.
- Sponge filters are affordable and easy to clean. They’re perfect for small to medium tanks.
- Canister filters work well for larger tanks and provide excellent filtration. Just ensure the output isn’t too strong.
- Check and clean your filter regularly to keep it working at its best.
Establish a Cleaning Routine
A consistent cleaning routine is key to clear water. You don’t need to overhaul the tank every week, but small, regular actions make a big difference.
The ideal water temperature for axolotls is between 16°C and 18°C (approximately 60°F to 64°F).
- Do a 25% water change weekly to remove waste and refresh the tank.
- Use a gravel vacuum to clean the substrate without disturbing your axolotl.
- Wipe down the tank walls if you notice algae buildup.
Monitor Feeding Habits
Your axolotl’s diet impacts water quality more than you might think. Overfeeding or feeding messy foods can quickly cloud the tank.
- Feed high-quality pellets, earthworms, or frozen bloodworms for easy cleanup.
- Stick to a consistent feeding schedule to prevent overfeeding.
Test the Water Regularly
Water quality plays a huge role in keeping the tank clear. Invest in a reliable water testing kit to monitor ammonia, nitrite, and nitrate levels.
- Test the water weekly, especially if you’re new to keeping axolotls.
- Ideal parameters: Ammonia = 0 ppm, Nitrite = 0 ppm, Nitrate = 20 ppm or less.
Cycle the Tank Properly
If your tank isn’t cycled, cloudy water is almost guaranteed. Cycling a tank means allowing beneficial bacteria to establish and process waste effectively.
- Use a water testing kit to ensure the cycle is complete before adding your axolotl.
- Avoid major cleanings that disrupt the bacteria.
Troubleshooting Cloudy Water in Specific Situations
Even with good care, things can go wrong. Let’s address some common scenarios and how to fix them.
Cloudy Water in a New Tank
If your tank is new, the cloudiness is likely due to a bacteria bloom. This is normal and should clear up on its own.
- Avoid adding chemicals to clear the water—they can harm your axolotl and disrupt the cycle.
- Be patient and keep monitoring water quality.
Milky White Cloudiness
Milky water often means there’s an excess of organic material like leftover food or waste.
- Increase the frequency of water changes until the tank clears.
- Check your filter to ensure it’s working properly.
Greenish Cloudiness
Green water usually means an algae bloom. This happens when there’s too much light or nutrients in the tank.
- Reduce the tank’s exposure to direct sunlight or artificial light.
- Consider adding live plants to compete with algae for nutrients.
Cloudiness After Cleaning
If the water looks worse right after cleaning, you might have disrupted the beneficial bacteria.
- Stick to partial water changes and avoid scrubbing everything at once.
- Use a water conditioner to remove chlorine, which can harm bacteria.
Pro Tips for Long-Term Success
Keeping your axolotl’s tank clear is an ongoing process. Here are some tips for maintaining clarity over time.
- Quarantine new additions like plants or tank mates to prevent introducing contaminants.
- Use a pre-filter sponge on your filter intake to catch debris before it clogs the system.
- Keep a log of your tank maintenance and water test results to spot patterns and issues early.
Why Clear Water Matters for Axolotls
Cloudy water isn’t just a cosmetic issue—it can impact your axolotl’s health. Axolotls are sensitive to water quality, and murky conditions can stress them out or make them sick.
- High ammonia levels from decaying food can cause ammonia burns.
- Poor water clarity might signal low oxygen levels, which can make your axolotl sluggish.
- Stress from bad water conditions weakens their immune system, making them prone to illness.
Wrapping It Up: Keep That Tank Clear and Healthy
Keeping your axolotl’s tank water clear isn’t as hard as it might seem. With the right setup, regular maintenance, and smart feeding habits, you can enjoy a beautiful, healthy environment for your aquatic buddy.
Test the water often, watch for signs of trouble, and adjust your routine as needed.
Your axolotl deserves the best care, and a clear tank is a big part of that. Start with small changes today, and you’ll see a big difference in no time.
