1. if the fishy smell of the

fish pond is heavy, it is necessary to reduce the feeding density. Because there are too many fish, the excrement of fish is also a lot, which leads to the water becoming fat, a large number of microbial reproduction, will produce a fishy smell. If you want to solve the problem, you can keep the fish separately and divide them into pools according to their size, which is also better for feeding.

2. Change the water

regularly. The best way to remove the fishy smell of the fish pond is to change the water. Because the fish pond is relatively large, so the ordinary method of changing water is not feasible, there must be a water inlet and drainage outlet, first part of the water is discharged, and then water can be injected into it. The place of drainage should be blocked to prevent fish from escaping from the fish pond.

If the fish pond is stagnant water, the water quality will deteriorate quickly and produce a heavy fishy smell. By activating the stagnant water, it can play a role in maintaining water quality, so that the fishy smell will be smaller. If you want to turn stagnant water into living water, you can install a pump in the fish pond. When the pump runs, it drives the water to flow, which can also increase dissolved oxygen.

4. Clean up

the fishy smell in time because the source of the fishy smell in the fish pond is the residual bait and feces at the bottom of the water, so cleaning up these things in time at ordinary times can also reduce the fishy smell in the fish pond. In addition, in daily feeding, controlling the amount of feeding can also reduce the content of organic matter, thus avoiding the water becoming fat, helping to improve the water quality and prevent the fishy smell from becoming heavier.
