1
Plan to remove the algae before changing out the water in your fish tank.
Once a week, remove and replace about 10 percent of your fish tank's water using a water pail.
-
2
Put on a pair of rubber gloves before scrubbing the tank.
-
3
Reach into the tank with an algae scrubber and scrub the algae off the walls of the fish tank.
Use only an algae scrubber, which you can find at a pet supply store -- household scrubbers and sponges may contain chemicals that are harmful to your fish.
-
4
Scoop water out of the fish tank using your pail, catching free floating algae as you can.
-
5
Catch the rest of the floating algae with an aquarium skimmer and throw it away.
-
6
Replace the water you removed from the tank with new water.
