How to Deep Clean Old Fish Tank Sand

Whether you’re thinking of renewing the old sand in your fish tank or want to reuse it, you’ll need to deep clean it first.

In this article, we’ll go over how to deep clean your aquarium sand in a few simple steps.

How to Clean and Disinfect Old Fish Tank Sand

Before you start cleaning the old sand in your fish tank, you’ll need to make sure you have the necessary supplies.

Here’s what you’ll need:

  • A bucket or container
  • Scoop or dustpan
  • Boiling water
  • Bleach

Step 1: Empty the Fish Tank

The first thing you’ll want to do is to remove everything from the fish tank, except the sand. This includes any decorations, plants, filters, water, and of course any fish. You just want to leave the sand at the bottom of the tank.

Step 2: Sift the Sand

Once you’ve emptied the tank, use a scoop or dustpan to sift out as much of the debris and organic matter as possible. This will make it easier to deep clean later on. Make sure to discard any solid waste in a trash bin.

Step 3: Transfer the Old Sand to a Bucket

After giving the old sand a good sifting and removing any large debris, you’ll want to transfer it to a large bucket or container. This will make it easier for you to deep clean the sand without making a mess.

Step 4: Disinfect the Old Sand

To actually clean and disinfect the old sand, we will only need one ingredient: boiling water. Bring a pot of water to a boil and pour it over the old sand in your bucket or container. You can use a large scoop or ladle to stir around the sand as you are pouring the boiling water so that each grain of sand gets exposed to the heat.

Allow the sand to sit for around 10 minutes so that any organic matter or bacteria is killed off. After the time has elapsed, you can use a sieve to strain out the excess water and debris from the sand.

Note for old sand with a lingering smell: If the old sand your trying to clean has a smell to it that isn’t going away, you can try adding a small amount of diluted bleach to the boiling water before pouring it over the sand. This will give the sand an extra cleaning boost and help kill off any remaining bacteria or organic matter. I recommend adding 1 teaspoon of bleach with a gallon of water.

Step 5: Rinse with Cool Water

Once all of the debris and organic matter has been removed, it’s time to give the sand one last rinse. Use cool water to rinse away any residual debris, and make sure you give the sand a good stir as this will also help disinfect it.

Step 6: Dry the Sand Thoroughly

Finally, once your sand has been thoroughly rinsed and disinfected, it’s time to dry it out. Spread the wet sand out on an old towel and leave it to air dry for a few hours. Once the sand is completely dry, you can return it to your fish tank or store it in an airtight container for future use.
