What's wrong with the smelly water in the fish tank?

Low frequency of water change: the water in the fish tank may smell bad because the water quality has changed. The feces and food residues in the fish tank will rot and deteriorate after being in the water for a long time, which will eventually lead to the smelly water quality.

Fish injury: the fish in the fish tank is injured and inflamed, which will also cause the water in the fish tank to stink.

Insufficient oxygen: when the water in the fish tank is insufficient in oxygen, the problem of odor will also occur.

The smelly water in the fish tank can be solved according to different reasons:

1. Increase the frequency of water change: If the water quality is too poor, you can increase the frequency of water change to keep the water clean. If fish can't accept frequent water changes, filters can be installed to slow down the deterioration of water quality.

2. Isolated culture: If the fish is injured, the injured fish can be fished out, treated separately and cultured separately.

3. Keep enough oxygen: If it is caused by the lack of oxygen in the fish tank, the breeder needs to install an oxygen pump to keep enough oxygen in the water.
