How to Clean a Fish Tank

Keep your fish healthy and your fish tank clean with these simple steps.

You will need

  • A large plastic cup
  • A large bowl
  • A scooping net
  • A sink
  • An algae scrubber
  • Clean gravel (optional)

Step 1 Use a large plastic cup to remove water from the tank to a large bowl. Scoop fish from the dirty tank and put them in the bowl.

Step 2 Turn off the filter on your fish tank. Remove half of the dirty water using a cup, and dump it into a sink.

Step 3 Clean the inside of the tank with an algae scrubber. Rinse and scrub until the glass is clean.

Step 4 Scoop out the rest of the water until you get to the gravel at the bottom of the tank.

Step 5 Refill the tank with clean water and restart the filter. Let the filter run for about an hour.

Step 6 Scoop your fish from the bowl to the tank, and let them enjoy their newly cleaned home.
