You should change the water in your tank at least once a week, if not more often. If the water becomes cloudy or smells, replace it immediately with clean water.

Steps

Method 1 of 3: Take the fish out of the aquarium temporarily

1. 1 Fill a separate large bowl with fresh water.
2. 2 Take the fish with a net and put it in a bowl of fresh water. Use a large bowl to give the fish plenty of room to swim; she will probably rush about in unfamiliar surroundings.

Method 2 of 3: Refresh your tank contents

1. 1 Empty the old water from the aquarium.
2. 2 Wash and brush gravel and other decorative items in a bowl of warm water and a little salt. Then place it all in a sieve and sprinkle it over with hot tap water. Set aside. Change the Water in a Fish Bowl Step 4.webp}
3. 3 Clean the aquarium with warm salt water. Avoid soaps and detergents that can leave chemical residue in the aquarium. Rinse thoroughly with warm water.

Method 3 of 3: Refill the tank

1. 1 Put gravel and decorations back into the aquarium.
2. 2 Fill the aquarium with room temperature water.
3. 3 Use the aquarium net to remove the fish from the fresh water bowl.
4. 4 Place the fish in an aquarium with clean water.
5. 5 Ready.

Tips

• Cleaning the water in your aquarium will keep your fish's environment clean and allow you to change the water less often. Consult an expert or local pet store for advice on water treatment.
• If you prefer not to purify your aquarium water, use bottled spring water to replace the dirty water.
• It is better to reach the fish with a small bowl with smooth and not sharp edges. Be patient and wait for the fish to calm down and stop rushing around, as this could damage it. Wait patiently, then carefully remove the fish. When using a net to transfer fish to a bowl, it may suffer from trying to breathe. If you are using a landing net, the transplant bowl should be next to the aquarium for minimal disturbance to the fish.
• Don't buy too many fish or choose small fish so they don't get too crowded in the tank.

Warnings

• Make sure the water in these containers is at room temperature before placing the fish in the bowl of clean water or back into the aquarium.
• When using a dechlorinator, be sure to follow the manufacturer's instructions to avoid harming your fish.
