The very nature of a terrarium is a contained space of nature, by definition.
You just need to use filter paper. use the filter paper than just pour the water and sand on the filter paper. the sand will go to the filter paper while the water will go straight to the beaker or anything below it. That is how you separate it. To separate sand and water you could pour the mixture through a filter. The water would pass through the filter but the sand would remain on top of the filter. If you didn't need to save the water you could evaporate the water and leave the dry sand behind. Or allow the sand to settle and carefully pour off the water first. Then allow the remaining water to evaporate.
Since sand is not soluble in water and salt is, you can add water to a mixture of sand and salt, and then pour away the salty water into a different container, leaving behind the sand. If you need to recover the salt as a solid substance, you can boil away the water, or if you are not in a hurry, just let it evaporate.
No, separating sand from water is a physical process as the chemical identities of the sand and water remain the same.
A simple filter would be suitable for separating sand and water. An alternative would be to evaporate the water, leaving the sand behind.
Fish tanks are often used to make terrariums, but to support aquatic life (fish) one needs to use the tank as an aquarium. For supporting land-living life (terrestrial life) one needs to user the tank as a terrarium. Aquariums need to be water tight, while terrariums may or may not need to be.
Typically, terrariums create a small environment mimicking the larger environment the sample came from. Terrarium are filled with air; if filled with water, they would be aquariums.
"AQUARIUMS" use water and "TERRARIUMS" use land.

Gets kind of big for most terrariums
There are a number of types of terrariums: 1. Terrarium kits are available that focus on certain plants and animals. E.g. desert or cactus terrariums 2. Hanging glass terrariums are really snazzy and a great piece of decor for your house 3. Plant terrariums focus on plants and don't contain animals 4. Animal terrariums can be a home to lizards, bearded dragons and snakes. 5. Aquarium terrariums are terrariums that have been made using a fish tank.
Peat moss works well in terrariums.
you need sand paper glue real sand tape and water
It would need to be a type of wood that doesn't rot, probably red wood.
To make sand harden, first you need water. Without water, sand is very soft, and soft sand is horrible for making sand castles or any sand sculptures. But if you pour water on sand, then leave it alone for a few hours, it should harden all by itself. But even though the sand is hardened, it is not unbreakeable, so be careful.
