Unplug your tank's pump and remove the light and cover.
Clean the sides of the aquarium gently with your scrub brush. You can do this without having to remove decorations or your fish
Perform a partial tank change. Remove approximately a quarter of the water from your tank. Remove it by sucking on the hose siphon and allowing the old water to run into the bucket.
Add four gallons of fresh water to your tank, making sure to use a tap water purifier if you use tap water in your tank. Tap water purifiers differ by brands. Follow the directions on the bottle to make sure you have the right mixture. Replace pump, cover and light. Allow your tank to settle for at least an hour.
Apply the algae control drops according to the directions on the bottle. Directions may vary with different brands. Make sure you follow the directions carefully or you could harm or kill your fish.
