What You Need to Know About Aquarium Algae

Algae takes many different forms, but none of them are particularly desirable in your home aquarium. In addition to making your tank look dirty, algae can compete with live plants and other photosynthetic organisms for valuable nutrients. Keeping algae under control in your tank is an essential task and, fortunately, not a very difficult one.

Here are some tips to keep algae under control:

  • Limit your tank lighting to 10 to 12 hours of broad-spectrum light per day – avoid leaving your lights on for too long or algae could grow out of control.
  • Perform routine water changes to remove detritus and other solid waste from the substrate in your tank as it decomposes it provides food for algae to grow.
  • Place your tank in a location away from direct sunlight – the heat and light from the sun can increase algae growth.
  • Keep your levels of phosphate, nitrate, and iron in check – these are the top nutrients algae needs to grow, so avoid over-fertilizing your tank and check your water parameters regularly.
  • Be sure to use a three-stage filtration system – removing solid and dissolved wastes helps control algae by removing excess of substances it needs to grow.
  • Keep the water quality in your tank high by performing small water changes every two weeks and larger water changes every month.

In addition to putting these tips to use, you might consider adding some algae eaters to your tank. Algae eaters come in many shapes and forms ranging from certain species of fish to aquatic snails. Just be sure that the one you choose is well-suited to your existing tank parameters.

Removing aquarium algae doesn’t need to be a long, complicated process. With the right tools, you can take care of it quickly and, with the right maintenance routine, you never have to worry about it getting out of hand. Use what you’ve learned here and with our top product picks to keep your tank algae-free.
