Instructions
Scrape the algae off the sides of the tank using a metal scraper. This works great for the thicker, stringy algae known as "hair" algae.
Scrub off any stubborn algae with a specialized algae scrub. This pad is very abrasive. You can also use it on the decorations.
Reduce the lighting in the aquarium. The brighter the tank, the more algae will grow. Try moving your aquarium away from direct light; or turn off the lights an hour earlier each day.
Introduce an algae-eating fish like an otto cat or a plecostimus. These fish thrive on algae and can help keep your tank clean.
Perform regular water changes. Change about 20 percent of the water once a week.
