One of the most common problems that fish tank owners face is the dreaded green stuff - algae. We're regularly asked "How do I get rid of it?!" And there are a number of things you can try.
They're pretty straight forward, and allow you to scrape the algae from the walls of your aquarium without scratching the glass. Many have rotating heads which allow you to clean all angles and get in to the smallest spaces in your tank and among the plant life. Some scrapers have multiple attachments that perform a variety of tasks, such as a gravel rake and sponge for cleaning.
Along with algae treatments and algae pads, scrapers can make a great addition to your algae busting kit!
