Both the grass tank and the fish tank are a small ecological cycle. If they are not filtered, although they can be raised, they are not in good condition, and the water quality is still very muddy, so they will lose their ornamental value. For the grass tank, filtration can provide a certain amount of gas, but also can absorb some impurities to keep the water clean and sanitary.
1. Cylinder body: The grass cylinder must have a cylinder first. There are many specifications for the cylinder. The smallest one is 30 cm, and the larger one is 400 cm. Generally, the larger the water body, the more stable the water quality will be. However, limited to cost and management, usually choose small and medium-sized cylinder, 60 cm cylinder is enough, material is recommended float white glass and ultra-white glass.
2. Lighting: The grass tank is mainly used to raise aquatic plants. The growth of aquatic plants cannot be separated from sufficient light, so it is necessary to install lighting equipment in the tank. At present, the T8 lamp tube has a high cost performance. If the water body is deep, the metal halide lamp can be used, and the led lamp is not recommended. Supplementary light can promote photosynthesis of aquatic plants and improve water quality.
3. Bottom bed: Since you want to plant aquatic plants, you need to lay something on the bottom of the jar. The commonly used thing is aquatic plant mud. This kind of thing is suitable for novices. Generally, it will be eliminated in 1-2 years, otherwise it will be powdered and seriously affect the water quality. For experienced people, you can use river sand, ceramsite and fairy soil as the bottom bed.
4. Carbon dioxide: In order to make the aquatic plants photosynthesize better, it is necessary to prepare a carbon dioxide device 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. There should be a pressure reducing valve and a fine adjustment valve on it. At the same time, a refiner and a diffusion barrel are also needed.
