There are many varieties of tropical fish, and the main methods of breeding are:

First, water
1. Water quality Artificial breeding of tropical fish requires water quality as soft water or low hardness water, and the pH is preferably weakly acidic or neutral. The acidity is strong. The tropical fish have difficulty in breathing and grow slowly. The alkalinity is strong and the pupa tissue of the tropical fish will be corroded.
2. Change water (1) partially change water. It sucks the feces, residual food, and other contaminants from the bottom of the tank. The amount of water absorbed is preferably 1/4 of the amount of water in the cylinder. Then add the same amount of fresh water that has been air-conditioned or chemically dechlorinated at the same temperature. The number of waterings is twice a week in autumn and winter, and three times a week in spring and summer.
(2) Change all water. All the equipment in the fish tank should be taken out, the water grass and fish should be removed, placed in other containers of the same temperature as the original water, and the cylinder wall and the bottom of the tank should be scrubbed with a sponge. Change the water every 2 months to 3 months.
Second, the temperature of tropical fish is extremely sensitive to temperature, if the temperature is not suitable, it will soon die. The temperature of most tropical fishes is preferably 20 °C to 24 °C, and the water temperature during the breeding season is 25 °C to 28 °C. The temperature difference between day and night can't exceed 4 °C.
Third, oxygen should be planted in the fish tank a certain number of plants, because the aquatic plants will produce oxygen when photosynthesis, so that the oxygen content of water increases. At the same time, timely removal of dirt, frequent water changes, etc., can also increase dissolved oxygen in water.
Fourth, the light placed in a sunny room to put the fish tank, it is best in the morning and evening when the sun is insufficient, each accepts about 1 hour of sunlight; if there is no sun in the room equipped with fish tanks, light should be used to water plants, with 60-watt incandescent bulbs Or 40 watt fluorescent lamp shines every day for 6 hours. Light can make tropical fish grow faster and make the fish more colorful.
Fifth, raise the tank to raise tropical fish, stocking density depending on the size of the fish tank. For those who fish for the first time, the lower the density, the better, and need to add an air pump. For the matching of the same tank fish, quiet fish can not be mixed with offensive fish; large fish can not be mixed with small fish. There are many options for feeding tropical fish, such as fish, red worms, or packaged feeds suitable for different types of tropical fish. Raw bait and live bait are washed to control the source of the disease.
1. Select a low-power controller. The controller will work 24 hours a day. If its power consumption is large, it will consume part of the power. A good choice is a controller that consumes less than 1 mA.
2. Select a controller with high charging efficiency. The controller of the MCT charging mode can automatically track the high current of the panel. Especially in winter or periods of insufficient light, the efficiency of MCT charging mode is about 20% higher than other charging modes.
3. Select the controller for bidirectional power regulation. Controllers with power regulation have been widely promoted. When there are few pedestrians at night, one-way or two-way lighting can be automatically turned off to save electricity. It can also adjust the power of the LED lights.
In addition to the above power-saving functions, attention should also be paid to the protection functions of the controller for components such as batteries. In addition, when setting the under-voltage protection value of the controller, try to adjust the under-voltage protection value to ≥ to prevent the battery from over-discharging.
