How to Remove Algae From Sand

Sustaining an aquarium requires constant cleaning and maintenance, such as controlling algae growth in the sand and on the glass. Two kinds of algae grow in aquariums: green and brown. Green algae is considered a sign of a healthy, flourishing aquarium ecosystem, whereas brown algae may be a sign of poor oxygen or light levels in the water. There are a number of methods for keeping algae growth in check within your aquarium.

Instructions

    • 1

      Run your fingers through the sand to loosen the algae and allow it to float in the water during your weekly aquarium cleaning routine.

    • 2

      Scoop the loose algae out of the tank using the net. The aquarium filter in your tank will filter out the rest of the loose algae that you are unable to capture with the net.

    • 3

      Wipe the glass sides of the tank with an aquarium cleaning sponge. Gently scrape off any algae that has developed there.

    • 4

      Purchase algae-eating snails, such as Malaysian trumpet snails, to keep algae growth in check.

    • 5

      Replace your tank light with a new, bright fluorescent bulb to increase light levels in the aquarium and inhibit algae growth.

      Add algae-removing chemicals to the water as a last resort if the other algae-removal methods have not fixed the problem after a month of regular cleaning. Follow the directions and safety precautions on the package.
