How Do You Clean an Aquarium Substrate?

Published in Aquarium Cleaning 4 mins read

Cleaning your aquarium substrate, like sand or gravel, is crucial for a healthy tank environment. The primary method involves using a gravel vacuum (also known as a siphon). Here’s how you do it:

Cleaning Aquarium Substrate with a Gravel Vacuum

The video reference, ![Part of a video titled Cleaning aquarium sand, gravel and substrate. - YouTube](), demonstrates the process of using a gravel vacuum effectively. The basic technique can be broken down into the following steps:

  1. Get the Siphon Going:
  • Place one end of the gravel vacuum (the wider tube) into the aquarium substrate.
  • Place the other end (the hose) into a bucket below the level of the aquarium.
  • Start the siphon by gently moving the wide tube up and down in the water. You may need to manually create a siphon by using your mouth to suck the hose end or use a hand pump on the gravel vacuum, depending on the type you have. The water should now start flowing from the aquarium, through the tube, into your bucket.
  1. Gravel Cleaning Action:
  • Once the siphon is running, carefully move the wider end of the vacuum through the substrate.
  • As you move the vacuum, the suction will lift the gravel and debris.
  • The gravel will spin around and fall back into place, while the waste will be pulled into the siphon tube and into the bucket.
  • It's important to avoid burying the vacuum too deep in the substrate to avoid disturbing beneficial bacteria in the deeper layers.
  1. Keep the Siphon Going:
  • As the video demonstrates, it is important that the siphon continues flowing to the bucket below, so that you are continuously removing waste and water from your tank.
  • According to the video, you may have to "shake" the tube to keep the water going.
  1. Water Changes:
    • The water removed during substrate cleaning acts as a partial water change. This helps to maintain healthy water parameters in the aquarium. You should replace the water removed with fresh, dechlorinated water.
  2. Frequency:
    • How often you clean the substrate depends on your aquarium's specifics. A general guideline is to clean it weekly or bi-weekly during regular partial water changes. Be more frequent with high bioload tanks.
  3. Substrate Type:
    • The process is slightly different for different substrates:
      • Gravel: The gravel vacuum works well with gravel substrate, easily removing debris trapped between the pebbles.
      • Sand: For sand substrate, avoid digging too deep, as this can disturb the sand bed. Instead, hover the vacuum just above the sand to remove waste without pulling too much sand.

Things to Remember:

  • Do not do a 100% water change. Substrate cleaning is a part of the partial water change you need to do. Only remove about 25-50% of the total volume of water in your tank at a time.
  • Do not clean all the substrate at once as this can remove too much beneficial bacteria. Clean sections of the substrate each cleaning session.
  • Ensure that the water you use to refill the tank is temperature-matched and dechlorinated.
  • Observe your fish during cleaning.

By following these steps, you can efficiently maintain a clean and healthy aquarium substrate.
