Things You'll Need
- Gravel vacuum
- Plastic/rubber hose
- Electrical tape
- Bucket
Instructions
Attach the plastic/rubber hose to the back of the gravel vacuum.
Place an empty bucket on the floor in front of the aquarium to be cleaned.
Using the electrical tape, securely fasten the other end of the hose to the interior wall of the bucket.
Take the gravel vacuum and start moving it back and forth in a pumping motion in the aquarium's water until you've created a syphon; the water from your tank should begin flowing up through the hose and down into the bucket.
Begin pressing the mouth of the gravel vacuum down into the gravel. The syphon should be strong enough to visibly extract the dirt and debris hidden within the gravel, while weak enough not to carry up the gravel itself.
Repeat Step 5 over all of the tank's gravel until clean. Do not let more than a third of the tank's water drain.
Replace any drained water with fresh, dechlorinated water.
