Hi welcome to my channel—before we begin don't forget to subscribe and hit the bell icon guys
Our first step is to prepare finely sieved sand and
cement in a ratio of two parts sand to one part cement
Mix until smooth and add water as needed
Prepare a cardboard box according to the aquarium's size then add padding for safety
Mix the cement dough then spread it evenly to form the cliff's floor
Position the powerhead for the sand fall and filtration
system then install the ping setup for the sand fall
Prepare a sheet of styrofoam and coat it with cement
paste install it at the back of the waterfall installation
Smooth each side of the stereofoam with cement mortar
Now let's shape the cliff for the falling sand first
This is the ping installation for the filtration system
Now let's set up the space for the powerhead
In this section we raise the back part higher to achieve a broader view
Add a few stones to increase the weight of the embankment so it won't float when we fill it with water
stall road pattern at the bottom
this road pattern is made from sheet stereofoam adhesive
Then we install the pattern for the railway sleeper pad
Add stereofoam to shape the rocks on the
cliff then coat each side with cement mixture
Now we're installing the road pattern for the upper section
Then we continue to shape the falling sand cliff
First apply a layer of cement mixture to the railway sleeper pads
continues to shape the cliff's formatio
Now let's make the cover for the powerhead area first
The next step is to coat the road pattern with cement mixture
Next we add rock reliefs to each side of the cliff to
enhance its shape and make it look more like natural rock
The placement of stereofoam and stones during every
cliff construction must be carefully monitored folks
If there are too many rocks the cliff will become
extremely heavy conversely if there is too much styrofoam
The cliff will float when we fill our aquarium with water
Now let's make the railway track cushion first
Make sure to pay close attention to how it's made guys
Get the roots ready for your tree guys
Secure the roots to the cliff using a cement mixture
The root I'm using here comes from the senggani tree folks
After the dry cliff open the box and then we'll paint the cliff right away guys
First we paint the cliff black—just a quick
note the paint I'm using here is acrylic folks
Next we'll apply a dark brown shade brushing it evenly across the
entire cliff surface especially over the rocky relief areas guys
And for the last one let's go with a light brown guys
Just apply it thinly across the cliff's surface
Don't forget we need to paint the road markings with white paint okay guys
Now let's install the railway tracks first
the railway tracks are made from bamboo
and make sure the bamboo is old enough alright guys
Add a miniature bamboo house to enhance the cliff we've created
Prepare synthetic grass for leaves
Cut and measure according to the tree branch
Then bond it using hot glue okay guys
Next prepare synthetic grass for the shrubs
Just use silicone glue to stick it together guys
and finally add miniature cars and trains as finishing touches to the cliff we've created
Bond using silicone adhesive
The cliffside is already beautiful
isn't it Let's set
it up right away
Set up the aquarium and don't forget to add the sky background guys
Next carefully lower the cliff into the aquarium using a rope
The water's fresh so let's head straight to exploring this beautiful natural panorama cliff guys
