This time we will make an aquarium cliff with a size like the one in this video.
And in this video we will try to make everything from scratch.
We will start by making the pipe circuit first.
And here are the materials and tools we use to make the pipe circuit.
The first step we determine the location of the power head.
For information, the power head I use is the 1600 power head.
Cut the neck of the rivet to make a sand input.
Lock the pipe with a cutter.
And please follow the steps in this video.
Cut the bottom end to form the letter V.
Insert into the rivet that we cut earlier.
After that, we cut the pipe until it is even with the rivet neck that we cut earlier.
And the following is the appearance.
For the next step, please see how to make the pipe circuit for the sand input.
Prepare sand that has been sifted and cemented with a ratio of 2 sand and 1 cement.
Stir until smooth and add enough water until it becomes a cement mixture that we are ready to use.
Pour the cement mixture to the bottom of the carton as a concrete floor.
Prepare a sheet styrofoam that we have measured according to the needs and cover one side with cement mixture.
After that, we stick it on the cardboard wall which will later become the outer wall of the concrete.
We also cover the inside of the styrofoam with cement mixture.
Next, we put the sand input pipe circuit.
In addition to sand input, we will add air bubbles in the making of this cliff.
We will make this air bubble a mountain hut with a small size.
The back side of the cliff we make higher than the front to get a wider view.
We make the back of this cliff open to make it easier to install the power head.
Add a few stones to add weight to the cliff.
Because if there is too much styrofoam, the cliff will expand when we fill it with water.
Continue to shape the cliff for the sand input.
We put a pattern for the highway.
Add a few pieces of used styrofoam to form the character of the cliff.
Then you scrape each side with cement mixture.
Make a mountain hut with a small size for an air bubble.
Scrape the pattern of the highway with cement mixture.
After the shape of the cliff is finished, we add a relief on the surface of the cliff.
This relief is to reinforce the shape of the cliff so that it looks like a natural cliff in nature or mountains.
Next, we prepare the pine roots for the tree.
Glue or directly paint the roots to the cliff using cement mixture.
After the cliff is dry, remove the cardboard on the right and left sides as well as the back.
After that, the cliff can be directly colored.
The first step is to paint with black as the base color.
Flatten the entire surface of the cliff.
As information, the paint we use is acrylic paint.
This paint is safe and does not smear in water.
The second step is to paint with dark brown.
Wipe the entire surface of the cliff, especially on the relief.
And the last one, we paint with light brown.
Wipe thinly on the surface of the cliff.
For the mountain slope, we paint it red.
For the road sign, we paint it white.
Add a miniature bamboo house to beautify the cliff we made.
Glue the bamboo house miniature to the cliff using silicone glue.
Prepare synthetic grass for the leaves in the tree.
Cut or cut according to the size of the tree, then please see how to make the leaves.
To attach it, we use burning glue.
Next, we prepare synthetic grass for the bushes.
We attach it to the cliff using silicone glue.
And the last one, we prepare a miniature car to complete the cliff we made.
Glue the miniature car to the cliff using silicone glue.
Well, the aquarium cliff with a beautiful natural panorama theme is done.
Great, right? Now it's time for us to set it up.
Prepare the aquarium and don't forget to install the sky background.
Also install the power head and filter cotton.
Insert the cliff into the aquarium using a rope carefully.
Also install the air hose and connect it to the engine.
Fill the water to the full.
Then put the fine silica sand into the sand input container.
The aquarium with a beautiful natural panorama theme is ready to be displayed in your guest room.
