1. To make an ecological fish tank, it is suggested to choose better aquatic sediment as the material in the fish tank. Commonly used are: Wuwei mud, Ada mud and so on. It is suggested that some entry-level aquatic plants should be selected first, and the foreground grasses are: dwarf pearl, mini cow hair and South American cross flower; The grass in the middle scene is: Shui Rong, pepper grass, crown, water orchid and round leaves; The grass in the background is: palaces, pagodas, louvers, cress and so on.
2. The density of aquatic plants in the ecological fish tank is about 50%-75%, which makes it easier to control algae and provide adequate shelter for small fish and shrimp. The number of fish should be controlled at 1 cm, and fish should account for 1 liter of water. The water quality should be controlled at pH 6-6.5 and GH 1-8. The water temperature should be controlled at about 23-27℃. If possible, using carbon dioxide will make aquatic plants in a better state.
3. If you choose a good heating pipe, you don't need a thermometer, and its temperature control is still very accurate. Of course, it would be better to have a thermometer, but don't use glass, it is easy to break. You can choose an electronic thermometer if you have the conditions. The lighting depends on your needs, whether it is brighter or deeper. You can choose two 40W white tubes or add a red tube. Some people like to make the fish shine.
