But some time when you overfeed your fish and there a lot of food left that make the cleaning aquarium is not a fun game to solve it; especially when your tank has several algae and other dirty debris. How to clear up your dirty fish tank right now?

Prepare some necessary equipment beforehand

Although cleaning a fish aquarium is not complicated, you should prepare some essential tools in advance. If not, you will get stuck at any part of the rinsing process. I just suggest you some that I think it is vital. You enable to select some or change your real situation.

  • Algae scraper
  • A razor blade (if you have an acrylic tank, you will need to use a plastic razor blade)
  • Bucket (optional)
  • Filter brush
  • Paper towels (optional)
  • Aquarium glass cleaner (if you own a glass tank)
  • Bleach solution
  • The salt solution (optional)


Clean the inside of the tank first

When you have some algae buildup on the tank, you just need to get a new sponge to clean. You can move fishes to another bowl temperately while wiping off the glass.

You enable to take a sponge with grinding side if you need to have extra scouring power. When you do not want to touch the tank deeper, you should find a tool with the long handle. This category is so popular at any local aquarium shop.

Combine a scraper

In case you have tough algae buildup on your aquarium, you should use a scraper at the same time.

Fortunately, this tool is easy to find at any aquarium store. Or you may find a similar brush to handle this task. To ensure all algae and dirty debris cannot stick on the tank, you should also use a vacuum.

In case the scraper is not good enough, you will select a razor blade to get rid of the algae completely. Modify the tool at a 45-degree angle the tank and rake the aquarium gently to avoid cutting yourself.

Wash the outside of the aquarium

Most people often forget to keep clean the outside of their aquariums. To be honest, I do not know the reason, but I think they are lazy to do that.

Or sometimes they think that the outside part is not important to draw attention. The fact is that the outside is also essential to make a great tank at all.

Luckily, it is quite easy to undertake this task as you just need to get a cloth and wipe off. You can get a wet cloth with soap to remove soiled debris. Also, you do not have to use an aquarium filter for the outside part.

Clean the aquarium filter

When the outside of the aquarium is clean, you should also rinse the aquarium filter. However, you also need to wait for a couple of weeks to do this task.

The main cleaning task you have undertaken can disturb all good bacteria on the plants, rocks, and gravel. These will imbalance the ecosystem of your tank. And toxins still generate all-time in the aquarium water.


Try algae eating species

This method is a good idea to prevent algae buildup for a while in your tank. Some fishes and snails can eat algae as their delicious meals, so you are not tiring to remove algae all time. Nonetheless, you should know which species are suitable. This is the main point to stay ahead in this solution. Basically, you can try some species like:

  • Malaysian trumpet snails
  • Ramshorn snails
  • Nerite snails
  • Otocinclus
  • Siamese algae eaters
  • Flag fishes
  • Twig catfishes
  • Bristlenose plecostomus
  • Rosy barbs
  • Amano shrimps

Get more plants

Believe or not, putting more plants in the tank could stop algae buildup as these consume the similar light and nutrient which algae do.

Furthermore, plants help your aquarium more beautiful and fishes have more places to hide when they feel uncomfortable.

When selecting plants for the tank, you should think of the conditions for growing plants as well. Plants have different light and temperature requirements.

Attempt an automatic cleaner

This method is wonderful for busy aquarium owners. It is also incredible to diminish algae completely.

You may consider an automatic aquarium glass cleaner by placing the cleaner on the aquarium and turn it on.=

Do not stay near the aquarium as it is dangerous for you. This way is ideal for those who own a glass aquarium.

Additionally, it is not affordable to pay as the price could be over $200. Most of the automatic cleaner has a rechargeable battery and a replaceable scrubbing pad.

Please note that you should reposition the automatic cleaner if you need to keep clean carefully on the sides of the aquarium.

Do not miss out decorations and rocks

Sometimes, you can forget clean decorations and rocks in the aquarium. When the inside tank is a bit clean, you enable to remove artificial plants, decorations, and rocks which have algae or dirty debris.

Do not use soap or detergents because these do not work well on these surfaces. Basically, an excellent scrub and an algae scraper can get rid of rocks, decorations, and plants.

With difficult debris, you should use bleach and soak these items for 15 minutes. Rinse with fresh water after tough scrubbing. Dry air can remove residual bleach.


Final Words

Mostly, a dirty fish aquarium is the consequence of algae growth. Thus, you should prepare everything to remove it along with other dirty debris. You enable to change the aquarium water, but do not do it immediately as good bacteria should be destroyed.
