How can we keep the water clear without changing it?

The water quality of fish tanks directly affects the health of fish, so it is very important to keep the water clear in the process of raising fish. If fish water is not changed in time, water quality can be stabilized by increasing oxygen and biota at the bottom of fish culture. Here are some ways to keep your fish tank healthy without changing water!

1. Use filtering equipment

Filter is an essential equipment in the process of fish culture. The main purpose of installing the filter is to filter out harmful substances such as fish manure, fish food residue and ammonia gas, and keep the water quality clear and transparent. If the aquarium is large, it is recommended to choose an external filter, because the external filter has greater filtering capacity, which can ensure sufficient water flow and is easy to maintain internal hygiene.

2. Regular oxygenation

Oxygen content will affect the clarity and stability of water, so the aquarium needs to be oxygenated in the form of mechanical oxygen or biological oxygen within a certain period of time. Increasing oxygen regularly is beneficial to the inhibition of unfavorable substances and the positive growth of flora. Under normal circumstances, increasing oxygen about three times a day can stabilize the water quality of fish tanks.

Control the number of fish

There should not be too many fish in the fish tank, which is the premise of keeping the water clear. If there are too many fish, there will be more harmful substances in the water, and the fish tank will soon inhibit the flora and make the water quality worse. Therefore, when raising fish, the number of fish should be controlled according to the size and habits of fish tanks and fish. It is suggested that the fish density should be controlled according to 1 liter/strip to ensure clear water quality.

4. prolong the feeding cycle of fish

Feeding fish is also an important factor affecting water quality. Excessive feeding will lead to water quality deterioration and increase pollution, while prolonging feeding time will make fish adapt to the environment, reduce pollution and make the water clearer.

5. Regularly carry out aquarium sanitation.

Regular sanitation of fish tanks is one of the important means to maintain water quality. Regularly remove the sundries at the bottom of the fish tank, timely clean the filter screen of the filtering equipment, clean the water changing tools and so on. This regular maintenance can increase the water flow and oxygen content, which is very helpful for the optimization and maintenance of water quality.

It should be noted that even if the above methods are used to maintain the water quality of fish tanks, fish farmers need to check the water quality of fish tanks regularly and change the water in time. Generally speaking, it is enough to change the water once every two weeks to one month. The best time depends on the water quality change of the fish tank and the state of the fish, and the water change time is selected according to the actual situation. By combining the above methods, your aquarium can always maintain clear and transparent water quality, so that fish can grow healthily.
