Instructions
Consider purchasing fish that can control your tank's algae levels. Fish like the Flying Fox or "twig" catfish will eat algae off plants and other surfaces, but come with all the concerns of adding any kind of fish to your tank. Go to your local pet or fish store, describe the specific circumstances of your tank and ask what would be an ideal algae-eating fish.
Clean live parrot feathers gently with a toothbrush. Many types of algae will come off easily, in long strands which can be wrapped around the brush. Other types, particularly the dark gray "brush" algae, will need to be worked at more vigorously. If a parrot feathers' small leaves have become completely choked with algae, don't bother with the toothbrush; proceed to the next step.
Remove the parrot feathers from the tank and search for a clean section. If you can find one, tear all the algae-encrusted pieces off of it and throw them away, then replant what's left.
Keep algae growth down, especially on plants, by ensuring that your tank's carbon-dioxide levels are always correctly balanced with the light you're providing. As a general rule, two fluorescent tubes with photo-periods of 12 hours should be sufficient for a single fish tank.
How to Remove Algae From Parrot Feathers
Parrot feather is a fast-growing, slightly bushy aquarium plant with many small leaves that can sometimes accumulate algae. Cleaning these plants is similar to any kind of algae management -- it's a duty that can be shared between you and your fish. Manual solutions, as well as preventative measures, can be as useful as adding some new wildlife.
