Change water-a tired and happy thing

　　

Change water-a tired and happy thing

the fish tank was quarantined half a month ago, and the water was changed every four days. The water in the fish tank was still green.

After the tank is cleaned, the water is changed and the cotton is washed.

After washing for two hours, my back aches and pains, I have to put it down slowly

Half a day passed by, looking at the results after hard work, I was blessed with joy and beauty.

　　

Friends, how often do you change water?

========How did the fish friends of the Xianglong Aquatic Alliance comment==

　　Le brother _ gentle and bad man Yuyou said: hard work, dont soak the cotton (recommended)
Zhao Guogong Zi Peng Yu Yu said: a lot of medicine
Holding a walnut, Yuyou said: Change the water in three days and wash the cotton the next day.
The little prince in the village of Shayu Yuyou said: If there is dry and wet separation, you dont need to put cotton in this way. Change the cotton quilt into a bacterial house. Put one or two layers of cotton on the bacterial house.gatheredtropical fish indonesia
