Precautions for the use of new fish tanks

One: Soak in concentrated salt water for one day, rinse with clean water, add tap water and connect all filtering and auxiliary equipment, power on and run at full power, and add potassium permanganate to the water until the water turns purple.
Two: Run with potassium permanganate for about 5 hours, and wait until the color of the water turns dark red. At this moment, the properties of potassium permanganate have been completely degraded. Then replace the water and add ordinary tap water.
Three: Turn on the filter, turn on the air pump, after 12 hours of turning on, you can feed water.
Four: The decomposition of organic matter needs to consume a lot of oxygen, which will reduce the oxygen content of the water body, which not only threatens the survival of fish, but also is not conducive to the growth and work of aerobic bacteria. Replenishing the loss of oxygen in the water in time is of special significance when the concentration of organic matter is high.
