The 11 Steps To Remove Scratches From Glass Aquariums

To remove the scratches from your glass aquarium, just follow these simple steps and they will be gone in no time at all.

1. Buy a little container of cerium oxide polish.

This is a material often used to polish the jewelry, but can also be used to buff out small and medium-sized scratches in aquarium glass.

2. Remove enough tank water so you can get to the scratch.

This might mean draining all of the water, in which case you will need to move your fish to a holding tank for safety.

3. If there is any water left in the tank.

Then Cover it with plastic wrap to avoid getting any cerium oxide or other substances in the water. Use tape to secure the plastic wrap in place so it does not move or sink below the waterline.

4. Get yourself a hard rubber disk

With a buffing pad and attach it to your electric drill.

5. Follow the directions on the cerium oxide.

Then mix it with water. Put the cerium oxide and water solution into a spray bottle for easy distribution.

6. Cover the buffing pad with the cerium oxide solution.

Get the pad nice and wet, but not so wet that it drips or flies all over the place when you turn the drill on.

7. Turn the drill to its lowest setting.

Then start buffing out the scratch. Press hard enough for decent pressure but not so hard as to break the glass or shift the aquarium.

8. If the glass is getting too hot from the friction of the drill and buffing pad…

Simply spray it with some water or some more of the cerium oxide solution to cool it down.

9. Continue buffing the glass…

Until the scratch is no longer visible.

10. Use a clean cloth

And wipe away any cerium oxide residue.

11. Put the water…

And fish back into the aquarium.
