A suction cleaner, often called a gravel vacuum, is used to remove waste and debris from the substrate of your fish tank during a water change. Here's how to use one effectively:
Step-by-Step Guide to Using a Gravel Vacuum:
-
Preparation:
- Ensure the gravel vacuum is clean and in good working condition.
- Prepare a bucket to collect the dirty water.
-
Starting the Siphon:
- Submerge the rigid end of the gravel vacuum into the fish tank.
- Hold the tubing end over the bucket, but do not submerge it in the bucket.
- Quickly move the rigid end of the gravel vacuum about a centimeter down into the gravel and then release your thumb to create the vacuum. This action starts the siphon process, causing water and debris to flow up through the tube, as mentioned in the provided reference.
-
Cleaning the Substrate:
- Once the siphon is flowing, gently move the rigid end of the vacuum just above the surface of the gravel. Avoid burying the rigid end of the vacuum too deeply, which might suck up the gravel itself.
- You'll see the dirty water and particles being drawn up. This is how you remove waste that would otherwise decompose in the aquarium, causing harmful imbalances in the water quality.
- Continue this process of hovering above the gravel along the bottom of the tank, covering different sections of the substrate until you clean the entire bottom of the tank.
-
Controlling the Flow:
- If the water flow becomes too strong, you can lift the vacuum slightly from the substrate.
- Also avoid getting too close to the gravel, in order to reduce the amount of gravel being drawn into the vacuum.
-
Stopping the Siphon:
- Once you've cleaned the substrate, or when the bucket is nearly full, you can stop the siphon by removing the rigid end of the vacuum from the tank water. The flow will stop.
-
Water Change:
- Because you’ve removed water with the vacuum, you will then refill the tank with fresh, conditioned water.
Tips for Effective Use:
- Avoid Disturbing Fish: Clean around your fish carefully, avoiding abrupt movements.
- Don't Over-Clean: Aim for a balance of cleaning the waste and debris, but also avoid removing too many beneficial bacteria that reside in the gravel.
- Regular Cleaning: It's good to do a partial water change with substrate cleaning every 1-2 weeks, depending on your tank's needs.
- Multiple Passes: If your substrate is very dirty, you may need to go over it more than once.
By following these steps, you can effectively use a gravel vacuum to maintain a healthy and clean environment for your fish. Remember, this process helps to remove the 'Gunk', as described in the video, that accumulates in the gravel.
