The straw tank can feed without filter, but the water quality is turbid and completely lost its ornamental. For the straw tank, it will become dead water without filtration, which has a great impact on the water body. Generally, the straw tank needs to be selected. Generally, it is 60 cm long and made of float white glass or ultra white glass. Lights shall be installed inside to provide light for water and grass. There should also be a bottom bed so that the grass can be planted on it. 1、 Whether it is a straw tank or a fish tank without a filter, it is a small ecological cycle. If it is not filtered, it can be raised, but the state is not good and the water quality is still very turbid, so it will lose its ornamental value. For the straw tank, filtration can provide a certain amount of gas, absorb some impurities and keep the water clean and hygienic. 2、 What equipment does the straw cylinder need? 1. Cylinder: the straw cylinder must first have a cylinder. There are many specifications of the cylinder, the smallest is 30cm and the larger is 400cm. Generally, the larger the water body, the more stable the water quality will be. However, limited to cost and management, small and medium-sized cylinders are usually selected, and 60 cm cylinders are sufficient. Float white glass and ultra white glass are recommended in terms of material.
2. Lighting: water plants are mainly cultivated in the grass tank. The growth of water plants is inseparable from sufficient light, so lighting equipment needs to be installed in the tank. At present, T8 lamp tube has high cost performance. If the water body is deep, metal halide lamp can be used, and LED lamp is not recommended. Supplementary light can promote photosynthesis of aquatic plants and improve water quality.
3. Bottom bed: since water plants are to be planted, some things should be paved at the bottom of the tank. Water plant mud is commonly used. This kind of thing is suitable for novices. It should be eliminated in 1-2 years, otherwise it will pulverize and seriously affect the water quality. For experienced people, river sand, ceramsite and immortal soil can be used as the bottom bed.
4. Carbon dioxide: in order to make water plants photosynthesis better, a carbon dioxide equipment needs to be prepared in the cylinder to supplement carbon dioxide into the cylinder. Generally, different types of carbon dioxide bottles should be selected according to the size of the cylinder, with pressure reducing valve and fine-tuning valve, refiner and diffusion barrel. （CaoGangBuYongGuoLvQiHangBuHang，CaoGangXuYaoNaXieSheBei）
