Aquarium with Double Walls DIY

In this example, I use 2 cylindrical plastic boxes to make one aquarium.

Remove all stickers.

The box dimensions: the top is about 16 cm, the bottom is about 14 cm, and the box is about 12 cm high.

The narrower bottom allows one box to fit inside of the other box for compact storage.

I am going to use it for building an aquarium with double walls.

Cut off the bottom of one box.

Use scissors to trim the cut edge if necessary.

We have made the inner wall!

Put the bottomless box/ inner wall inside of the box with the bottom.

Let’s set up an aquarium.
Add gravel.

Add dechlorinated water.
2 liters of water fit in this aquarium.

The inner wall can be moved effortlessly in and out.

Add different types of plants.
In this example, I add hairgrass.
Check my video on how to anchor it ;)

Also, I add land moss that grows underwater.

This is fast growing land moss that I keep in a nursery with seed shrimps.

Most likely, seed shrimps are already in my new aquarium ;)

A cutting of Elodea goes into this aquarium as well.

To reduce algae growth — allow plants to grow in this aquarium for couple weeks or more before adding fish or snails.

I add a pair of guppies, Campeloma snails, Frogbit plants, Marimo ball, and some land mosses.
This aquarium is all set and suitable for fish under 4 cm.

It could take weeks or months, depending on your aquarium fish care routine, for algae and dirt to accumulate on the walls of your aquarium.

When you think it is time to clean up, gently pull the inner wall out.

Use a washcloth to clean both sides of the inner wall.

Watch out for the fish when re-installing the inner wall back into the aquarium!
Chase the fish and move all plants away from the walls!

The double wall makes cleaning simpler disturbance free.

Have fun and happy aquarium ;)
