in the courtyard fish pond? If you want to maintain the water quality in the courtyard fish pond, you'd better install a filter device in the pond. It should be noted that according to the size of the fish pond, the specifications of the filtration equipment are different, so we must ensure that the flow is sufficient, so that the water quality can be maintained. Usually this kind of fish pond can only raise some eurythermic fish, can not raise tropical fish, can consider raising some koi, goldfish, white cloud golden fish and view back medaka and so on.
make the water in the fish pond in the courtyard green? 1. Control the illumination: The water in the fish pond in the courtyard turns green, indicating that the algae in the pond is growing in large quantities. These are generally Chlorella. Although green water is not harmful to fish, it may burst algae in the fish pond, and then it is very troublesome to pour algae, so it is necessary to limit its growth, and the best way is to control the time of light.
2. Reduce feeding: The formation of green water is not only related to light, but also to nutrients in water. These nutrients themselves are decomposed from organic matter, which comes from feeding food and fish feces, so by reducing feeding, the growth of green algae can also be limited, and then eliminated.
3. Change the water properly: The fish pond in the courtyard can also change the water. As long as the water is changed regularly, the water body can be kept clean and sanitary, so as to prevent the proliferation of algae. It should be noted that the change of water should not be too frequent, otherwise it will stimulate the fish and cause stress reaction.
