Water quality monitoring is one of the indispensable links in the breeding and management of indoor koi. The main items of daily water quality monitoring include metal ions such as water temperature, pH value, salinity, dissolved oxygen, ammonia nitrogen concentration, nitrite, nitrate and bacteria.
Koi has been raised for a long time, although it has been cleaned up on weekdays, it cannot be completely cleaned up. It is necessary to change the water in a timely manner. The main methods and steps are as follows:
1. Drying water: in order to ensure that the temperature of new and old water is the same, it is necessary to take measures to dry water 1 ~ 2 days before changing water. The tap water is injected into the storage tank or idle koi pond in the same place and left for 24-48 hours. When the temperature of the new water and the old water is gradually the same, the water can be changed. Cooling water can increase oxygen and escape chlorine.
When changing water in spring, summer and autumn, the temperature of new water is better 0.5 ℃ ~ 1 ℃ lower than that of old water, while in winter, the temperature of new water is 0. 5% higher than that of old water. 5 ℃ ~ 1 ℃.
2. Liquid absorption and extraction: first, use a rubber hose to inhale the upper clear water into the cleaning container for use. Then take out water plants, stones and other ornaments, rinse with clean water for use.
3. Fishing for brocade carp: pick up the koi with a net and cover the top of the net with a spoon to prevent the carp from jumping out of the fall; if you are raising a small koi, it is appropriate to use a spoon to bring water into the sucked upper layer of clear water.
4. Clean the carp tank: after taking out the discolored and smelly sand, rinse and wipe the aquarium with clean water many times until it is tasteless. Can use decontamination powder, if still not, wipe repeatedly with a cleaning cloth dipped in vinegar to make the glass clear and clean.
5. Restore the aquarium: spread sand, place stones, inject water, recommend and put in brocade carp in order, and then add new water that has been dried to the original water level.
