2 Best Aquarium Sand for Axolotl

From water chemistry to filtration to aesthetics, in an axolotl’s aquarium, a substrate is extremely crucial.

Preparing an axolotl tank necessitates paying closer attention to the substrate; you might overlook while setting up your tank.

When setting up an axolotl tank, one of the first considerations should be the substrate.

Perhaps you’re unclear whether or not a sand substrate will benefit them, which sand products are the best, and more!

After reading this post, you’ll understand the advantages of using aquarium sand for axolotl as a substrate, our top two picks, and why.

Benefits of Using Sand for Axolotl

Sand is an excellent substrate for your Axolotl for a variety of reasons. To begin with, sand substrates are gentle on your axolotl’s feet, whereas rough or slick surfaces will cause stress and possible injury. 

Secondly, sand enhances the looks of your Axoltol’s tank greatly. 

Additionally, unlike gravel substrate, if an Axolotl accidentally consumes gravel, it might result in stomach blockage, resulting in death

Furthermore, It also keeps your tank clean and balanced because of its natural bacteria and water filtration properties.

Did you know that these salamanders aren’t particularly fond of light and that reflections on the tank floor’s bare glass might cause them stress?

But using sand as your substrate can cover the bottom of the tank, reducing light reflections.

Finally, because a sand substrate is already good for your aquarium in the long run, it saves you money. 

Please keep in mind that the aquarium sand axolotl substrate is only safe for adult axolotls; it is not safe for juvenile axolotls.

Buyer’s Guide: What to Look for in Good Sand For Axolotl?

For axolotl tanks, sand is generally recommended as the ideal substrate. Choosing the appropriate sand can also help keep your axolotl healthy while in captivity.

There are four primary factors to consider when choosing sand as a substrate for your Axolotl.

It should be secure, natural, easy to clean, and competitively priced. Below, we’ll go through each of those four characteristics in further detail.

Safe for Axolotl

The most critical point to keep in mind is to choose fine, smooth sand. This way, the axolotl will not be harmed if it consumes it. As a result, safety is the primary concern in this case.

Another essential factor to note is avoiding sand that will alter the PH of the tank.

Similarly, the smoothness/fineness of the sand should be considered. Finally, the sand should not harden because this will cause filter clogging.


Apart from the smoothness and fineness concerns, there is also the toxicity issue to consider.

Toxin-free axolotl sand is ideal. As a result, colored sand or dyed sand is out of the question in this instance.

For instance, you may discover that black axolotl sand is not acceptable due to dyes (which can be hazardous). Otherwise, the axolotl black sand may be exceedingly fine and smooth.

However, because it contains dyes, there is a risk of toxicity, which makes it unsuitable. As a result, this is not an appropriate axolotl sand type. Naturally, the sand should also be beneficial to plants.

Select sand that can be utilized to anchor live plants and encourage them to thrive. Finally, the sand you purchase should not cloud the aquarium’s water.

Easy to Clean

Third, the sand should be simple to clean. Every owner, of course, wants a low-maintenance product, and an easy-to-clean sand substrate product falls into this category. It benefits both the axolotl and the owner.

Reasonable Expenses

The last characteristic on the list is the sand you would be buying must have a reasonable expense.

Of course, as an owner, we wouldn’t buy products that cost a fortune, but at the same time, is still high quality.

How to Clean Sand in Axolotl Tank

Cleaning aquarium sand, which becomes polluted with numerous debris, is a major task for maintaining a clean tank and a healthy axolotl.

Take note that every two weeks, your substrate should be cleaned. You can use a Siphon or a vacuum to clean the sand in your axolotl Tank.

Before sand cleaning, we recommend putting axolotl in a temporary tank. Because sand can become stuck in the axolotl’s gills, causing them to scrape.

For the sake of easier sand cleaning, you have the option of scheduling sand cleaning simultaneously with tank cleaning. This will help you save time.

Step 1: Sand should be stirred.

Create a “lovely” cloud in the tank by thoroughly stirring the substrate. Afterward, let your tank settle for five to ten minutes. Any dirt left in the water after the filtering process will often settle on top of the sand.

Step 2: Siphon The Dirt from The Sand Surface

Once all the dirt you want to vacuum is on top of the sand, take a siphon with a huge barrel, similar to a gravel vacuum, start it, and then move over the top of the sand slowly and carefully, scooping up all the material laying on top of the sand.

Avoid getting down into the sand, as this will result in your vacuum picking up the sand substrate and removing it from the tank.

Step 3: Clean Your Filter

After cleaning up the dust and debris on top of the substrate, clean your filter as soon as possible because it will have picked up a significant amount of dirt from the water when you stirred the sand.

Note: Throw the water that contains the Wastes.

After completing Step 3, you can now dispose of the waste-containing water in your lawn or plants.

Remember that you should not flush it because the accumulated waste may still contain sand, which can clog your toilet.

Step 4: Add New Sand

Add new sand, add all of the decorations, then place your reptilian friend back peacefully. Be gentle when placing back the axolotl, as it may take some time to adjust to the new substrate. 

Best and Worst Sand for Axolotl

Substrates are the materials used to line the bottom of an axolotl’s cage.

Due to axolotls’ delicate skin and curious nature, it is critical to carefully choose a substrate. This is done to avoid damage and ingestion during the feeding process.

The greatest axolotl substrate choices and possibilities include fine smooth, natural sand, Playsand, Aquarium filter sand, pure aquarium sand without dyes, silica sand, and Estes Stoney river.

Additionally, a blend of substrates will work, but cleaning will be more challenging.

Aragonite sand and black sand are among the types of axolotl-unfriendly sand.

Additionally, sand with a sharp edge, such as construction sand, sparkling sand (crushed rock), quartz sand, marine sand (rich calcium carbonate), and reptile tank sand should be avoided.

Aragonite sand, magnetite sand, and tinted sand are some of the worst sands included as well.

Final Verdict

In conclusion, axolotl tanks can be substrated with sand. In an axolotl aquarium, the sand used must be fine and smooth.

The axolotl’s delicate legs would be more at ease when walking on such a surface. Even if the axolotl eats it, it will not affect it.

In addition, the tank water’s PH should not be adversely affected by the sand. It should also be free of harmful substances, such as dyes.

Caribsea and Stoney River sands are two types of sand that can be used in an axolotl tank.
