How to Clean an Aquarium Glass Without Scratching

Having a clean aquarium glass is lovely to look at. So it’s important to clean it regularly on a weekly basis. Algae tends to grow on the aquarium walls which can be toxic to fish and plants. So it’s better to get rid of it before it grows and spreads over time.

It’s important to use clean materials when cleaning an aquarium. Scratching tends to occur when objects are trapped between the glass and your tool during cleaning. Things like sand, dirt, and sharp particles are the culprit in this kind of situation. Low iron glass is the number one victim of scratching since it’s made from a soft glass. The first thing to do before cleaning an aquarium glass is to remove foreign particles from the glass and your cleaning apparatus to prevent scratching.

Cleaning The Exterior

Use a soft towel rinsed in warm water and wipe it in the exterior of the glass. Always keep an eye on sand and gravel on the glass and remove them before wiping the towel on the glass. Hard water accumulations sometimes occur in the outer surface of the glass which can be cleaned by applying warm water and then wiped on with a towel. Keep out of domestic glass cleaning sprays as it can damage the glass and can be harmful to fish. Once dry, the exterior can now be wiped with a soft towel to remove any water spotting.

Cleaning the Interior

Now that you’re done with the outer part of the aquarium, it’s time to clean the inner part by using these 3 tools.

  1. Sponge

  • If there are signs of algae spreading on the inside, use a sponge and scrub it in a circular manner to where the algae is located. Make sure that your hands are clean before placing them inside the aquarium. Also, don’t spend too much time on the interior and clean it as soon as possible.
  1. Magnetic Glass Cleaner

  • A magnetic glass cleaner consists of two magnetic attachments which has a dual purpose, a cleaning pad and a scrubbing pad. Place the scrubbing pad inside the tank and place the cleaning magnetic part on the outside of the tank. Gently slide the tool over the glass especially where algae is present. Never forget to clean the magnetic cleaners after using. Avoid scrubbing too close to the substrate as sand and gravel might be caught between the layers of the cleaner and can result to glass scratches.
  1. Algae Scrubbing Blade

  • For thick and hard to remove algae, it’s time to use an algae scrubbing blade. Some magnetic cleaners are built-in with an algae scrubbing blade on the backside. Scratching the glass using the blade is highly unlikely as long as you use it properly.
