We’ll share multiple methods to do the glass cleaning process. Adopt the best one suits you. Let’s start the main discussion without further ado.
How to Clean a Fish Tank Glass
Before starting the details about cleaning a dirty fish tank glass, you should identify the problem you have, like an alga or calcium build-up, or it just becomes dirty from not cleaning or changing the water for a long time.

Identifying the problem and the reason behind it can help you prevent your fish tank’s glass from becoming dirty again in the future.
Now, there’re 3 best ways to clean your aquarium glass–
1. Manual Cleaning
2. Having Algae Eaters
3. Use an Automatic Cleaner
You can perform manual cleaning in different ways. Let’s talk about it one by one.
Wipe the Glass:
The most common way to clean the fish tank’s glass is to wipe it off by using a sponge. Having a mild alga in your aquarium, wipe it through a sponge.
Method 1: If you need some extra scrubbing, use a sponge with an abrasive side. Be careful not to have any sand on the sponge; your glass can get scratched from it. So, wash it thoroughly before using it in the fish tank cleaning.
Method 2: You can use a long-handle scrubber if you don’t want to use your hand directly.
Method 3: Using a fresh, dampen old towel is another way to clean your fish tank glasses.
Method 4: Among all the manual cleaning processes, the best and easiest way to clean your fish tank glasses is to use paper towels. Using a paper towel to clean the aquarium glasses helps you maintain your optimum aquarium’s pristine quality.
A Paper towel also won’t create any scratches on your fish tank’s glass. Paper can help you from not making a mess in the aquarium. Using other methods like a sponge or razor blade or something similar won’t hold the dirt or algae from falling into the water.
Yes, you can use a fresh dampen towel too, but to me, it’s easier to perform with a paper towel.
The second method of manual aquarium glass cleaning is scraping the algae from the glass.
Tougher algae need a scraper to remove from the glass. Aquarium stores have different tools for this job. You can buy an algae scrapper from there and use it for cleaning.
Razorblade is an alternative tool to algae scraper; if you don’t have an algae scraper, use this instead to clean your aquarium glass. However, if you have an acrylic aquarium, use a plastic razor for cleaning; otherwise, it can get scratched.
There could be a time when you don’t have an algae scraper or razor blade; what can you do then?
Don’t worry; there is another alternative you can use; if you have an old credit card or some pass/ID with a sharp edge, you can use those sharp-edged tools for scrapping.
Use an Aquarium Magnet:
The 3rd manual fish tank glass cleaning approach is to use an aquarium magnet. Aquarium magnet helps you to clean your fish tank without putting your hand into the tank. The scrabbing pad will be inside the glass; as you move the outer part around the tank, the inside will move too.
Always be careful about keeping the aquarium magnet in sand and gravel-free area. Don’t get it near them; they will catch those too, which will be hard to remove and cause a scratch on your aquarium glass.
Clean the pad after every time you perform cleaning. Also, don’t leave the magnet on your glass while not cleaning.
Use a felt under the outer magnet part, which will help you from scratching the glass.
Buy a stronger magnet for glass than an acrylic aquarium. Size shouldn’t be a problem; choose one which you feel comfortable working with.
Cleaning Outside Aquarium Glass:
Keeping clean the outside glass is also important. You can use a Paper towel or a fresh dampen old towel to clean the exterior aquarium glass.
Using a chemical to clean your glass isn’t recommended. If you want to use the glass cleaning chemical, spray it on a towel or wipe the glass. Don’t spray on the glass directly.
You can use vinegar to clean your aquarium glass. Only distilled white vinegar is safe to use.
Here’s an article on- How to Clean Aquarium with Vinegar.
Using Algae Eaters
Introduce different algae eaters into your fish tank. Fish, snails, and crustaceans that eat algae are an excellent way to keep your aquarium clean and fresh. Algae eaters will eat from the fish tank’s glass too. So, your target to clean the glass will be achieved.
According to your fish tank (freshwater or Saltwater) and size, put some algae eaters into the tank.
Some common aquarium algae eaters:
- Rosy barbs
- Flag fish
- Ramshorn snails
- Nerite snails
- Bristle nose Plecostomus
- Amano shrimp
- Siamese algae eaters
- Twig catfish
Use an Automatic Cleaner
If magnet cleaner or algae eaters don’t satisfy your need, you can have an automatic aquarium glass cleaner. It’s easy and simple, turn on the cleaner, put it into the aquarium, and leave.
Yes, that’s all!!
However, it will cost you some money, which is around $200 or more.
If you need to clean all sides of the tank, you need to reposition the cleaner, as it can’t turn corner sides.
