You’ve got an axolotl. They’re quirky, adorable, and undeniably fascinating. But here’s the deal—you’ve noticed the tank’s getting murky, and your little friend deserves better.
Cleaning an axolotl tank might seem overwhelming at first, but it’s easier than you think once you break it down.
Let’s get into the nitty-gritty of keeping your axolotl’s home sparkling clean and healthy.
Why Cleanliness Matters for Your Axolotl’s Tank

Your axolotl’s health heavily depends on a clean tank. Axolotls are sensitive creatures, and poor water quality can stress them out or even make them sick. A dirty tank can lead to bacterial infections, fungal growth, and ammonia spikes, all of which are dangerous for your pet.
For a filtered tank, it’s recommended to perform a 20% water change weekly; if unfiltered, a 20% change daily or every other day is necessary to maintain water quality.
Keeping the tank clean ensures:
- Stable water parameters.
- Reduced risk of illness.
- A happier, healthier axolotl.
Now, let’s get into how you can achieve that.
Prepping for a Successful Tank Cleaning
Before diving into the cleaning process, it’s crucial to have the right tools and a plan. Axolotls don’t like sudden changes, so minimizing stress is a priority.
Gather Your Supplies
Make sure you’ve got these essentials ready:
- Gravel vacuum or siphon.
- Soft sponge or algae scraper.
- Dechlorinated water.
- Aquarium test kit (for ammonia, nitrites, nitrates, and pH levels).
- Bucket specifically for aquarium use.
- Net or temporary holding container (if needed).
Pro Tip: Avoid using soap or harsh chemicals on any cleaning tools. These can leave residues that harm your axolotl.
The ideal water depth for an axolotl tank should be approximately 25-30 cm (about 10-12 inches) to provide adequate swimming space.
Test the Water First
Testing the water before cleaning helps you identify any imbalances. Check for:
- Ammonia: Should be 0 ppm.
- Nitrites: Also 0 ppm.
- Nitrates: Ideally under 20 ppm.
- pH levels: Between 6.5 and 7.5.
If something’s off, cleaning alone may not solve the problem. Adjustments to the filtration system or feeding habits might be necessary.
The Step-by-Step Cleaning Process
Cleaning an axolotl tank involves more than just scooping out debris. Here’s a detailed breakdown of what to do:
Step 1: Partial Water Changes Are Key
Axolotls thrive with partial water changes, not complete overhauls. Removing 20–30% of the water weekly helps maintain water quality without disrupting the tank’s ecosystem.
- Use a gravel vacuum or siphon to remove debris and uneaten food from the substrate.
- Replace the removed water with fresh, dechlorinated water at the same temperature as the tank.
Why Partial Changes Work: Complete water changes can eliminate beneficial bacteria that help break down waste. Keeping part of the original water preserves this balance.
Step 2: Clean the Substrate
If your tank has sand or bare bottom (both great choices for axolotls), cleaning is easier. Use a siphon to gently remove waste. For sand, hover the siphon above the surface to avoid sucking up the substrate.
Avoid Gravel: Gravel can trap waste and even be swallowed by axolotls, causing blockages. If you’re still using it, consider switching to sand or bare-bottom setups.
Axolotls reach maturity between 6 months and 1 year, which is essential for breeding in captivity.
Step 3: Scrub Tank Walls and Decorations
Algae buildup is common, but it’s easy to manage:
- Use a soft sponge or algae scraper to clean the tank walls. Avoid abrasive pads that could scratch the glass.
- Rinse decorations with tank water in your bucket. This keeps helpful bacteria intact.
Step 4: Check and Clean the Filter
Your filter works hard to keep the tank clean, but it needs regular maintenance too. Once a month:
- Rinse filter media in dechlorinated water to avoid killing good bacteria.
- Check for clogs or buildup that could reduce its efficiency.
Pro Tip: Never replace all the filter media at once. Stagger changes to maintain the bacterial colony.
Step 5: Inspect Plants and Hiding Spots
Live plants and decorations can accumulate waste over time. Trim dying plant leaves and rinse hiding spots like caves with tank water to keep things tidy.
Handling Your Axolotl During Cleaning
It’s usually best to leave your axolotl in the tank during cleaning to reduce stress. If you must move them (like during deep cleans):
- Use a soft net or container to gently transfer them to a temporary holding tank.
- Keep the temporary water at the same temperature and conditions as the main tank.
Reminder: Axolotls are delicate, so avoid excessive handling. Their skin is sensitive and can easily get damaged.
Maintaining Optimal Water Parameters Post-Cleaning
Once you’ve cleaned the tank, it’s important to monitor the water to make sure everything stays balanced.
Use an Aquarium Test Kit
Regular testing helps catch issues early. Check levels weekly and after cleaning. If ammonia or nitrites spike, troubleshoot by:
- Increasing water changes.
- Checking for overfeeding (uneaten food decomposes quickly).
- Ensuring the filter is working properly.
Avoid Overfeeding
Axolotls are messy eaters. Feed them small portions of high-quality food like pellets or earthworms and remove uneaten food after 15–20 minutes.
Why It Matters: Overfeeding not only wastes food but also leads to water pollution from decomposing leftovers.
Keep Up With Routine Maintenance
Consistency is your best friend when it comes to keeping the tank clean. Schedule tasks like:
- Partial water changes: Weekly.
- Filter checks: Monthly.
- Full decoration cleanings: Every 2–3 months.
Troubleshooting Common Issues
Sometimes, even with a solid routine, problems can pop up. Here’s how to handle a few common challenges:
Cloudy Water After Cleaning
This might happen if debris was stirred up. It usually clears within a day. If it doesn’t:
- Check for overfeeding or excess waste.
- Ensure the filter is functioning properly.
Persistent Algae Growth
Algae thrives in tanks with excess light or nutrients. Combat it by:
- Reducing tank light exposure to 8–10 hours a day.
- Keeping nitrate levels low with regular water changes.
Bad Odors
A smelly tank signals poor water quality. Test the water immediately and look for hidden waste under decorations or substrate. Address any imbalances promptly.
Tips for Long-Term Success
Keeping your axolotl’s tank clean gets easier with practice. Here are a few extra tips to help you stay on track:
- Invest in a good filter: A high-quality filter reduces cleaning frequency and keeps water parameters stable.
- Use live plants: Plants like java moss or anubias can absorb nitrates and improve water quality naturally.
- Create a cleaning schedule: Writing down tasks helps you stay consistent and avoids last-minute scrambles.
- Observe your axolotl: Changes in behavior, like reduced activity or poor appetite, can signal water quality issues.
Wrapping It Up: Keep Your Axolotl Happy and Healthy
Cleaning an axolotl tank might seem daunting at first, but with the right tools and routine, it becomes second nature. By focusing on partial water changes, substrate care, and regular filter maintenance, you’ll provide your axolotl with a safe, clean environment.
Remember, a healthy tank equals a happy axolotl. Take small, consistent steps, and you’ll enjoy many years with your unique aquatic buddy!
