How To Cycle a Fish Tank









Ensure a healthy, balanced environment in your aquarium by following this simple process.

You Will Need

  • A fish tank
  • A filter
  • Hardy fish
  • Water samples
How To Cycle a Fish Tank: Set up fish tank

Step 1: Set up fish tank

Set up your fish tank and filter system, then fill it with water.

Avoid using water with chlorine.

How To Cycle a Fish Tank: Stock with hardy fish

Step 2: Stock with hardy fish

Stock your tank with hardy fish, such as mollies, tiger barbs, white clouds, or guppies.

Hold off on goldfish; they are more vulnerable to disease.

How To Cycle a Fish Tank: Limit the number

Step 3: Limit the number

Put in just a few fish. Three 1-inch fish are sufficient if your tank is between 10 and 20 gallons.

Adding too many fish will result in excess waste and stress the fish.

How To Cycle a Fish Tank: Change the water

Step 4: Change the water

Change 10 to 15 percent of the water every few days.

How To Cycle a Fish Tank: Test a water sample

Step 5: Test a water sample

Test a sample of the water after a week. It should test high in ammonia with a trace of nitrate at this time.

Ask the pet shop where you bought the fish if they’ll test it. Many stores will do this for free or charge a small fee.

How To Cycle a Fish Tank: Continue the process

Step 6: Continue the process

Continue moderate water changes every two weeks. Cycling a tank takes up to eight weeks. Your goal is to establish a healthy colony of bacteria that live in the filter, removing ammonia and other toxins from the water.

How To Cycle a Fish Tank: Add more fish gradually

Step 7: Add more fish gradually

Add more fish gradually, and enjoy watching them thrive as a result of your diligence.

The animals in the “Oceanarium” at Chicago’s Shedd Aquarium consume over 650 pounds of seafood each day.
