How To Remove Scratches From Aquarium Glass?

We have all gone through this situation if you are a new aquarist or expert aquarist. There are many reasons why aquarium glass has scratches on them.

So, how to remove scratches from aquarium glass? Removing scratches is an easy task if the scratch is not deep.

Let’s begin,

How to remove scratches from aquarium glass

You can polish aquarium glass with cerium oxide, fill up scratches with liquid glass resin, or multi-purpose metal polish to remove aquarium scratches.

Aquarium glass can be easily scratched, making your fish and other aquatic creatures feel uncomfortable.

The best way to prevent scratches is by using a soft cloth and non-abrasive cleaner every time you clean your aquarium.

If scratches have already occurred, you can try using a commercial scratch remover or a polishing compound.

Determining the Scratch Depth

When trying to determine the scratch depth, you will need to consider the scratch’s length, width, and severity.

You can also use a magnifying glass to look at the scratch. If the scratch is less than .005 inches deep, it can usually be polished out.

If the scratch is greater than .005 inches deep, it will likely need to be filled with a clear epoxy resin.

To determine the length of the scratch, start at one end and measure to the other end with a ruler. To determine the width of the scratch, do the same thing but measure from side to side.

The severity of the scratch can be judged by how deep it appears to be. The scratch depth will also determine how long it will take to remove.

If the scratch is too deep, try to replace that aquarium glass panel, which will help avoid unnecessary risks.


Empty The Aquarium Before Removing Any Scratch

Before removing any scratches, you should remove fish from that tank and keep them in another tank. Remove any decoration, plants (live or plastic), and substrate (gravel or sand).

Now carefully wipe the Glass with a cotton cloth to remove the remaining water. Now you are ready to remove the scratches from your aquarium glasses.
