Cleaning Aquarium Glass

There are two sides to cleaning your aquarium – the outside glass and the inside glass. Obviously you would clean each very differently.

Let’s take a quick look at how to clean the aquarium glass on the outside first.

  • Use warm water to wet a soft cloth or paper towels
  • Newspaper works wonderful to clean the glass
  • You should not use spray cleaner, such as Windex, anywhere near the tanks, as the airborne spray can get in the water
  • For hard water crystals, soak with a cloth using warm water to dissolve
  • When cleaning acrylic use a cleaner specifically for it, as anything ammonia based will ruin it

Cleaning the inside of the glass can be just as simple. When you notice the algae building up on the inside of the tank, it is important to get in there and clean it off so that you can continue to enjoy the view of your aquarium.

This video can give you more tips on cleaning the outside of your aquarium, as well as mentions cleaning the inside.

3 Simple Ways to Keep Your Aquarium Glass Clean

Cleaning the inside of your tank does not have to be difficult either. There are three simple methods for cleaning the inside that will have you looking at a clean tank in no time.

The three methods we are going to look at are the simple sponge method, a magnet cleaner, and an algae scraper. You can choose which method you want to use.

1. Simple Sponge Method

  • Purchase a foam kitchen sponge; make sure that it doesn’t have added cleaner to it
  • Remove tank cover
  • Reaching in gently with your hand, slide sponge up and down the side to clean away the algae
  • Avoid over filling tank or rapid arm movements or water will spill over the top
  • Do not wash sponge out with soap and reuse

To see this method in action, you can watch the following video showing the sponge method being used to clean aquarium glass.

2. Magnet Method

  • Purchase a magnet cleaning set for your tank. The Mag Float cleaner (for medium tanks are a very effective choice.
  • Remove tank cover
  • Place the half of the magnet set with the cleaning pad on the inside of the tank, with the cleaning pad facing the glass.
  • Place the second magnet on the outside of the glass facing the inside magnet. The two magnets should hold the two pieces together.
  • Gently slide the outside magnet up and down to guide the inside cleaning pad along the inside of the glass.
  • Slide magnets over glass until all of the algae is removed.
  • Replace cleaning pad for each cleaning.

3. Algae Scraper

  • Purchase an algae scraper tool, such as the TOM Aquarium Algae Scraper, which comes with multiple attachments for cleaning.
  • Remove tank cover
  • Select the scraper attachment you would like to use
  • For tougher algae, you can use the pronged scraper
  • Slide the scraper up and down the sides to remove all algae
  • Avoid rapid motions, as water will slosh out over the top
  • Rinse the scraper and attachments in warm water for re-use
  • Never clean with detergents or put in dishwasher

Finishing Up

Whether you decide to get in deep with a sponge, stay dry with a magnet cleaner, or stick in a scraper, all three methods are easy and effective.

The worry of how to clean aquarium glass should not keep someone from owning a beautiful fish tank.

With a little time and the right tools, any tank can be sparkling clean and a joy to look at.

    Thanks for the article. Good info.
    Unfortunately, the big problem with my tank is white marks from calcium in the water. We are in a VERY limey region and all the tap water in the area is very very hard. Our bathroom chrome for example stays clean (after vigoreous vinegar cleaning) for less than a week. Actually, the white marks start with the first shower. We use a Britax water filter to make drinking water from the tap water, but that is less than a liter and the tank is 90L. Anyway, we still have some limescale in the kettle (in which we only use filtered water) so maybe it dosent even remove the calcium.
    would you happen to have any ideas?
    thanks in advance

    I forgot to say that the problem is a lot better since we removed the heater. However, we want to go back to using the heater and get some more interesting fish. The limescale actually builds with heat.. I forgot to mention that (but you probably already know that) :-)

    I have a 230 gallon tank that’s been sitting outside for years, now inside and cleaned with alge brush, rinnced and dried. Glass still shows film on inside. Any suggestions on making glass crystal clear? Thanks
