How to change the water in an ornamental fish tank

Keeping fish is a fun hobby that requires patience, and regular water changes are a key step in keeping the water in your fish tank clean and your fish healthy. This article will detail the correct way to change the water in an ornamental fish tank and provide some practical tips to help you accomplish this task with ease.

1. Why should we change the water regularly?

The water in your fish tank can accumulate harmful substances over time, such as ammonia, nitrites, and nitrates. These substances are harmful to fish health and may even cause death. Regular water changes can effectively dilute these harmful substances and maintain stable water quality.

2. Frequency and amount of water changes

The frequency and volume of water changes depends on the size of the tank, the number of fish and the efficiency of the filtration system. Generally speaking, it is recommended to change the water once a week, and the amount of water changed each time is 20%-30% of the total water volume.

3. Steps to change water

1.Preparation tools: Before changing the water, you need to prepare the following tools: bucket, siphon, water quality conditioner, and thermometer.

2.Turn off the device: Before changing the water, turn off the heating rod, filter and other equipment of the fish tank to avoid dry burning or damage to the equipment.

3.pump water: Use a siphon to pump out the sewage from the bottom of the fish tank and clean up the remaining bait and fish feces at the bottom.

4.add new water: Slowly pour new water into the fish tank. Note that the temperature of the new water should be consistent with the water temperature in the fish tank (the temperature difference does not exceed 1-2°C).

5.Regulate water quality: Add water quality conditioner to remove chlorine and other harmful substances in tap water.

6.Restart device: After the water change is completed, restart the heating rod and filter.

4. Things to note when changing water

1.Avoid full water changes: Unless the water quality of the fish tank has seriously deteriorated, it is not recommended to replace all the water at once to avoid damaging the ecological balance of the fish tank.

2.Pay attention to water temperature: The temperature of the new water should be close to the water temperature in the fish tank to avoid excessive temperature difference causing fish stress.

3.Use water conditioner: Tap water contains chlorine, which is harmful to fish and must be removed with a water conditioner.

4.Observe fish reactions: After changing the water, closely observe the behavior of the fish, and take timely measures if any abnormalities occur.

5. Frequently Asked Questions

Q: Why do fish float after changing the water?

A: It may be caused by insufficient dissolved oxygen in the new water or a large difference in water temperature. It is recommended to slowly pour in new water when changing water, and use an air pump to add oxygen.

Q: Do I need to clean the filter when changing the water?

A: The cleaning frequency of the filter should not be too high. Generally, it can be cleaned once a month. When cleaning, rinse gently with fish tank water to avoid destroying the beneficial bacteria on the filter material.

Q: Can I use rainwater to replace the water?

A: It is not recommended to use rainwater because rainwater may contain airborne pollutants that are harmful to fish.

6. Summary

Regular water changes are an important measure to keep the fish tank water clean and the fish healthy.
