Forming the aquarium

Forming the aquarium is one of the most fun and the most interesting things about aquaristics.

Before you start forming and arranging your aquarium, you have to purchase the following things: gravel or sand (or the combination of these two materials), which you will use to cover the bottom of the aquarium; water that stood for 24 hours at room temperature; a few stones for decoration. You could also purchase a piece of mangrove wood, which has positive influence on the chemical structure of water and gives that exotic look to the aquarium. Then you will need a few selected aquarium plants, peat (it is recommended to be granulated); then basic aquarium equipment like water filter, heater, air pump, air pump valve, thermometer and rubber tubes for air supplies. If you are planning to put some decorative stones on top of each other or to paste the stone blocks on the inner backside of the aquarium, you will also need the silicone. Use only a non-toxic 100% silicone sealant appropriate for the aquarium use.

When you purchase all these items, it is time to start forming the aquarium.

If you have decided to paste the stone blocks to the inner backside of the aquarium, this should be the first step to do. In your natural surrounding, you will find some bigger stone that you could split with hammer (for this purposes you cannot use limestone). Split it carefully into thin blocks. Then lay the aquarium on its backside and paste the stone blocks with silicone. You should paste the stone blocks in the way to resemble the natural environment. Leave the silicone to dry out for 24 hours.

After that, choose some place in your home, where you could put the stand and the aquarium.Put the 1 – 2 cm layer of sand or gravel on the tank bottom. We recommend purchasing this material in aqua store, and wash it few times in clean water before use. If you choose to take the sand or gravel from nature, it is very important to disinfect it with preparation or to boil it in water.

Scatter the peat on the top of this layer of sand. Do not exaggerate with it, it is enough to put 4 – 5 granules on 5cm². Then put another layer of gravel (sand) on top of it. This layer should be thinner in the front part of aquarium (approx. 5 cm), and thicker on the back of the aquarium (approx. 10 cm). Put the decorative stones and mangrove wood in the tank and try to set up the look of it in a way to resemble the bottom of tropical lake or river. If you have decided to put decorative stones on top of each other, join them together lightly with silicone. When the silicone dries, fill one third of the aquarium with water. The best way to do this is to pour water into the aquarium by using the bucket and tube on a siphon principle (a tube running from the liquid in a vessel to a lower level outside the vessel so that atmospheric pressure forces the liquid trough the tube).
Or you could pour the water in the tank manually, but to avoid steering the layers of sand and soil, put the plate in the middle of aquarium and slowly pour the water on it. This way the sand will stay unstirred.

When you filled one third of aquarium with water, you should plant the plants.At first remove all damaged or dry leaves; and it is important to cut down one third of plant’s roots with sharp scissors. Then gently take the plant for the root, carefully push it into the sand (gravel) and level the surface. Follow this procedure with all your plants, but be careful to plant the bigger and fast-growing plants in the back, and the smaller and low-growing plants in front of your aquarium.

In order to have a look of a real tropical aquarium, grow various aqua plants, but keep in mind that some plants grow faster than the other. However, it is better to have some more plants, as it could happen that some will wither. Some other plants will be tasty food for the fishes. If the plants start to overgrow, it is easy to thin them out.

After you have planted the plants, you should fill the aquarium with additional water up to the two thirds of a tank and set all the necessary equipment (filters, heaters, air pumps, etc.) on places where they will be less noticeable. Then pour the rest of the water in the aquarium, so the water level is 2 – 3 cm lower from the edge of the glass. Then plug the equipment on. Set the heater at approx. 20-25 °C. The temperature level in aquarium depends on kind of the fish you have planned to keep. You will need to top up the water from time to time. All the water that you pour into the aquarium has to be previously prepared and to stand for 24 hours. And remember to unplug ALL the wires before you do anything in or around the tank!

When you do these things, your aquarium is ready to receive its inhabitants.

You have to pay special attention when choosing the fishes. Every fish you buy has to be healthy, perky and lively. When buying the fish, consult the store employees about which kind of fishes can live together in your aquarium, because there are some kinds of fishes that do not tolerate the presence of other kinds. Do not put the purchased fishes directly into the aquarium. At first put the fishes into the aquarium together with a bag and water from the shop. Let them stay there for a while, until the temperature of water in the bag and the aquarium equals. If you put the fish directly from the bag into the aquarium, it could die because of shock.

It is recommended to purchase some preparation that prevents fish diseases, and put it into the water.

When you do all these things, it is time to sit in front of your aquarium and enjoy the wonderful view on nature you brought into your home.
