Using a Top Fin gravel vacuum is a simple process to keep your aquarium clean by removing debris and waste from the gravel. Here's a breakdown:
-
Starting the Siphon:
- Place the vacuum tube (the wider end) into the gravel.
- Place the other end of the hose into a bucket below the level of the aquarium. This is crucial for the siphon to work.
- Start the siphon. Most gravel vacuums have a built-in pump. If not, you may need to manually start the siphon (e.g., by quickly moving the gravel vacuum up and down in the water).
-
Cleaning the Gravel:
- Once the water starts flowing, gently push the vacuum tube into the gravel. The gravel will lift slightly, and debris will be sucked up.
- As the gravel tumbles, the waste is separated and siphoned away.
- Lift the vacuum tube slightly to allow the clean gravel to fall back down.
- Avoid getting dust/debris everywhere: If you see too much dust being disturbed (3:38 of the reference video shows this), pinch the hose to reduce the suction so you have more control.
-
Moving Around the Tank:
- Systematically work your way around the tank, cleaning the gravel in sections.
- Don't vacuum the entire tank at once, as this can disrupt the biological balance. A good rule of thumb is to clean about 1/4 to 1/3 of the gravel during each water change.
-
Finishing Up:
- Once you've cleaned the desired amount of gravel, remove the vacuum tube from the tank.
- The siphon will stop when the water level in the tank drops to the same level as the end of the hose in the bucket or when you lift the vacuum out of the water.
Important Considerations:
- Water Changes: Gravel vacuuming is usually done in conjunction with a partial water change. The amount of water you remove during vacuuming constitutes the water change.
- Fish Safety: Be careful not to suck up any small fish or invertebrates.
- Plant Care: Be cautious around plant roots. You don't want to uproot your plants.
