The main problem is that most aquarium fish feel well only in soft water. If taken for aquarium soil contains soluble salts of calcium, they will gradually move into the water and increase its rigidity, which will impact negatively on the inhabitants of the aquarium.
Therefore, the algorithm to find beautiful soil, washed, pour into the aquarium" is incorrect. Beautiful is not good, so the aquarium can't use coral sand, small rock, marble crumb, no matter how beautiful they look.
For aquarium will not fit and fine sand with grains of diameter smaller than 1 mm. Such a soil will be too dense, almost impermeable to water, it will begin the process of decay. In this soile bad feel of the plant, their leaves will be small and faded.
Alternatively, in the case of using fine sand in the aquarium, it is necessary to arrange the second plastic bottom with nasverlennye in it small holes. The distance between the bottom of the aquarium and the second bottom is 1-2 cm On the second floor in two layers is placed a fine mesh (not metal!), she poured the sand. From the space under the second bottom pump pumped out the water, thereby ensuring the forced circulation through the soil. Such second bottom is useful for any aquarium.
Best choice for aquarium soiland is small, with a diameter from 1 to 5 mm, gravel of quartz or feldspar. Pour it into a bowl, cover with water, drain the supernatant waste. Then rinse, actively stirring, until, until the water will not stay perfectly clean.
In that case, if there is a suspected high content of calcium, the soil must be treated with hydrochloric acid Bay for a couple of hours in a plastic basin. Then it should be no less than half an hour wash with running water to remove all traces of acid. To test whether the soile, calcium, splash him with hydrochloric acid or vinegar. If bubbles appear, the soil needs treatment with acid.
Aquarium ground, thus prepared, will not saturate the water with calcium salts, therefore, its stiffness will be a long time to stay at an optimal level. Sometimes novice aquarists only add water to replace evaporated is wrong, since it leads to a gradual increase in the level of rigidity. It is recommended not to top up weekly, but change is not less than 1/5 of the volume in the tank water.
Advice 2 : How to wash sand
Finishing works in addition to other construction materials may require a clean washed sand. To buy it is difficult, therefore, begs the question: "How to wash sand for yourself"? The choice of method depends on its quantity.
You will need
- containers of different sizes;
- frame with a stretched metal mesh;
- the blade;
- water hose;
Washing sand required a significant amount of clean water, as well as places to drain it. Therefore, identify and prepare the place where will produce washing. Pre-sift the sand through a metal mesh to filter out large fragments and debris. Move water with water hose.
This method is used when relatively small quantities of source material. Select is not very large, but wide enough pot, for example a basin. Pour back the sand and fill it with water. Well stir the mixture with a spatula. Drain the murky water. Repeat two or three times. Then, taking the basin in his hands, hold it under gently running water. Making a circular motion, gently tilt the basin so that contaminated water was gradually merged. To obtain a larger fraction of the sand faster and more energetic movements make stronger and tilt the container, in order to together with dirt leaving fine sand. Rinse until water is clear. Then carefully drain the water.
For more sand use the frame with a metal mesh or grid. The size of the frame should be about 1m2, and the cell size from 5 to 10 mm. the Frame should have a side height of 5 – 10 cm. position the frame horizontally, tucked under the corners for 3 – 4 bricks. Top cover the frame with burlap. Sprinkle an even layer thickness of 4 – 8 refer to spray the water into the frame and adjust the pressure so that the sand was not sprayed. Periodically changing directions, rinse the sanduntil the water under the frame is clean. Close the stopcock and leave the washed material in the frame to drain the water. In this method, the larger sand will be in the upper layer.
The way to wash sand in large volumes, is the following. Install at a slight angle metal bath. The bath area is about 3 m2, the sides are 30 – 35 cm Pour in a container of 10 to 12 buckets of sand, a little rethrownew it. Secure the hose at the top of the bath and fill it with water. Adjust the pressure so that the water slowly drained from the bottom. Upward gently stir until they begin to merge. Turn off the water. Select washed sand on a clean flat surface and allow to drain water.
Do not attempt to flush immediately large amounts of sand.
Washing sand better done with an assistant, constantly stirring the sand.
Advice 3 : What kind of sand for construction will need: washed or unwashed
Sand is rock, characterized by friability and flowability. Also this is an artificial material, consisting mainly of grains of rocks. Sand have many kinds with distinctive features and application possibilities. To get this breed can be in many places – rivers, ravines and quarries. River sand is considered to be blurred because, while career unwashed.
Construction – the common name of sand used in construction and repair works. Without it there can be no construction because it is widely used in the manufacture of concrete, mortar, cement, finishing works, often in engineering and construction as a septic tank or drainage. Often sand is used in agriculture and gardening farms, individuals and utilities to populate the sandbox on the Playground, in filters and water treatment system.
River (washed) sand
River sand is a premium material that is composed of additional impurities. It is extracted from the bottom of the river and does not contain clay or other minerals. Therefore, it is an indispensable material in construction. Widely used in the screed, masonry and concrete. It is often take for preparation of plaster.
River sand used in construction of roads – it is part of the asphalt mix. River sand comes in three sizes – small up to 2 mm, medium-2.8 mm to large mm to 5 mm. it has a high filtration coefficient, because of this it is often used in filtration and drainage works. The cheapest and most commonly used is a medium sand. Coarse sand in nature are hard to obtain, so its price is high.
Career (unwashed) sand
The extraction of such sand is produced in quarries, making it a lot of impurities occurring during fracture of rocks is the dust, quartz, clay, etc. this sand can have different properties depending on its place of production. Career, the cheapest compared to other types of sand. Often used in works of major volumes, such as roads, buildings, Foundation and production of concrete of high strength.
Unwashed sand quarry is often used in the preparation of plaster. In construction it is used only after purification from impurities, which greatly improves its quality. Despite the fact that the sand quarry is a time-consuming process of washing, unlike river sand, its price still remains low.
Of washed pit sand is obtained excellent material for concrete and brick production, for the erection of structures in road and housing construction. In addition, it is used in concrete production.
In construction is used as washed and unwashed sand. However, the use of washed sand, which price will be slightly higher, manufactured building materials are of high quality.
