Steps to make an aquascape for a 20 gallon tank

At present, you have an idea of the tools and equipment you will need. Soon, we will dive into specific steps to make an aquascape for an aquarium.

Step one: Determine the size and layout of the aquarium

In the first place, we should determine the size of the aquarium. In this segment, we will take 20 gallons tank as an example. Besides that, we should design the layout in our brains or draw on paper.

Step two: Adding gravel

Before any operation, it is recommended to place a level of gravel on the bottom of the aquarium, which provides support for rocks. Then smooth the gravel with a substrate spatula or your hands.

Step three: Adding rocks

Lay the rocks in the tank, and make sure they are stable. Then we can use aquascape adhesive to bone the rocks. By doing so, we can prevent the rocks from cracking or breaking the glass.

Step four: Adding wood

Place wood above the rocks. After placing them in an ideal manner, we can use aquascape adhesive to bone them with the rocks.

Step five: Adding sand and soil

Please notice here that do not mix the sand and soil. The aquarium is separated into three parts by the rocks. Then add the aquarium soil on the right and left side, and add the sand in the middle. Do not forget to smooth the sand and soil.

Step six: Place the aquarium sponge on the wood

Trim the aquarium sponge according to your requirements, and then place them on the wood. The sponge is for planting and growing plants.

Step seven: Planting aquatic plants

Before planting the aquatic plants, we can prune them with scissors. Next, plant them into the aquarium soil with the help of tweezers. On the other hand, we can apply some plants to decorate the wood, like moss.

Step eight: Adding water to the tank

Since the substrate is loose, the water in the tank will become cloudy if the substrate suffers a strong water flow. Therefore, we should put the aquarium sponge, a layer of plastic, or something like these above the soil and sand. After that, we can gently add water to the aquarium. However, it is better to make the water flow into the aquarium along the sponge. By the way, you can use a submersible pump or a cup to add water. Until the tank is filled up with water, do not forget to remove the aquarium sponge.

Step nine: apply the aquarium light and filter

After that, place the aquarium light and filter, and turn them on. The aquarium filter is essential for an aquarium. It can remove debris and cycle water in the tank.

Step ten: Change the water in your aquarium

The next day after adding water for the first time, you should change the water in the tank, then let it stands for about two days, finally, you can introduce fish into the aquarium after the tank cycle.

Tips for aquascape

Until now, we believe you have learned more about aquascape. For better aquascaping, there are also some tips.

  • There are various styles of aquascape, including diorama aquascapes, dutch aquascapes, biotope aquariums, iwagumis, jungle aquascapes, etc. You should determine the style you like before starting aquascaping.
  • Besides that, it is better to keep about 1.5-2 inches of the substrate to develop the roots of plants. When you apply plants, they should be pushed down about 1 inch into the soil. Accordingly, the plants will not be loose and detaching.
  • Moreover, fish, aquatic plants, and other creatures may possess different requirements for water parameters. You should research the suitable pH, GH, KH, and water temp for your tank, then test the water parameter in your tank.
  • Furthermore, freshwater or saltwater tanks require different rocks or plants, you should research which one is ideal in advance and then choose the best one.
  • On the other hand, the aquascape should follow the golden ratio. The small plants should be placed in the front of the aquarium, while the larger ones are usually placed at the back of the tank.
  • When you add water to the aquarium, it is critically crucial to cover the soil or sand. You should reduce the impact of water on the substrate, as well as prevent the water from flowing into the tank directly by covering the aquarium sponge or other non-toxic objects. Or you can let the water flow through your hands, and then flow into your aquarium.
  • More importantly, too many plants or decorations should be avoided in a fish tank. Please remember that fish require space to move and enjoy exploring around the tank.
  • Rocks and stones are always the focal points of aquariums.
  • After aquascaping, you should keep maintenance to make sure of the comfortable habitats.
