Attention when placing duckweed in fish tanks

1. Do not put a large amount of duckweed in a hot environment or during thunderstorms. Due to the special reasons of sultry weather, the amount of dissolved oxygen in the fish tank will decrease. If duckweed is put in at this time, the dissolved oxygen in the fish tank will be further reduced. In serious cases, it can easily lead to the death of goldfish.

Duckweed cannot be fed in the evening or at night because duckweed put into the fish pond in the evening or at night will consume a lot of dissolved oxygen in the water through its own respiration; and after goldfish are full at night, they will also It will increase respiratory oxygen consumption, both of which can lead to hypoxia in the pool water.
