Hello, welcome back to my channel, before we start, don't forget to subscribe and press the bell button, so you don't miss the latest updates from me.
Let's just prepare the sand that has been sifted and cement.
Mix and stir the sand and cement until smooth.
Add enough water until the cement mixture is ready for use.
Here I have prepared a cardboard that has been covered according to the size of the aquarium.
We first make the floor of the cliff by pouring the cement mixture to the cardboard that we have prepared.
After that, adjust the position of the power head and pipe installation for the sand to drip.
This is the type of pipe installation that we will use.
After that, prepare the styrofoam sheet that we have measured and cut.
Then we put it on the back wall of the cliff.
Likewise, for the side wall of the cliff, we also prepare the styrofoam that we have cut.
Don't forget to smooth each side of the styrofoam with the cement mixture.
On the back of the cliff, we also cover it with styrofoam.
This is to match the power head that we put on the back of the cliff.
We make the back of the cliff higher than the front.
This is to get a wider and farther view.
Next, we will make a river on the side of this cliff.
First, we make the pattern.
After the pattern is formed, cut and throw away the unused parts.
After that, we make a river wall on the right and left.
After the river wall is formed, we smooth the cliff base with the cement mixture.
Next, we shape the cliff so that it is similar to a natural rock.
We can use used styrofoam to form rocks on the cliff.
But remember that the styrofoam we use is not too much.
Because later the cliff will swell when the aquarium is filled with water.
We can add some rocks to form the cliff.
This rock is also used to add weight to the cliff.
But don't use it too much.
Because later the cliff will be very heavy.
We will use the balance between the rock and the styrofoam.
This time we will make a place where the sand falls.
It is made of waves and irregularities.
This will make the effect of the sand that falls look like a waterfall.
Next, we will install the road pattern.
We make this road pattern from styrofoam.
Then we complete the cliff that we made.
Remember, what we use is a mixture of styrofoam and rock.
After the shape of the cliff is complete.
We give character to the cliff we make.
By giving reliefs like natural rocks.
Finally, we flatten the road pattern with cement.
After the shape of the cliff is complete.
We prepare the sandstone for the tree.
We plant or directly root to the cliff using cement.
So that it is firmer and stronger.
After the cliff is dry.
Open the carton on the left and right sides and behind it.
After that, the cliff can be directly colored.
The first color is black.
We flatten the entire surface of the cliff.
As information, the paint I use is acrylic paint.
This paint is safe and durable.
We use it even though we soak it in water.
All creative friends.
For the first river, we paint it with dark blue.
Continue the second color for the top.
That is dark brown.
Wipe and smooth, especially on the reliefs.
And the last color for the cliff is light brown.
Wipe thinly, especially at the ends of the reliefs.
To reinforce the shape of the cliff.
The second color for the river is light blue.
Especially wipe on the edges between the river and the rocks.
And finally, add a little white on the edges.
So that it looks like a stream in a flowing river.
And for the road sign, we use white paint to paint it.
All creative friends.
Add a miniature of a bamboo house to beautify the cliff we made.
We can glue it using silicone glue.
Time for greening.
Prepare some synthetic grass for leaves and bushes.
First, we will make leaves.
Pay attention to how to make it.
We attach the leaves to the tree or root using glue.
Now we will make grass or bushes.
Also pay attention to how to make it.
We attach the bushes to the cliff using silicone glue.
Installing grass or bushes must be extra careful.
Don't let the character of the cliff be covered by the grass we install.
To complete the cliff we made, we add a miniature of a car.
We attach it using silicone glue.
Well, the aquarium cliff with a natural panorama theme that we made is ready.
Let's set it up.
Prepare the aquarium and don't forget to install the sunrise background.
Install the power head and also the filter cotton.
Insert the cliff into the aquarium using a rope carefully.
Fill the water to the brim and let's try it.
Pour the silica sand into the sand container.
And don't forget to install the lights.
The aquarium with a natural panorama theme is ready to display beautifully in your family's room.
