Aquarium algae isn’t a pretty sight, but it’s something that every aquarium owner is going to face eventually. Luckily, decreasing algae naturally can be accomplished by healthy tank care procedures such as water testing, the addition of plants and sea life, and regular cleaning and water swapping.
Once you know how to combat algae growth and keep your tank maintained, you’ll have no trouble keeping the many colors of algae at bay.- 1 Determine the different colors of algae in your tank. Different kinds of algae thrive in different aquarium conditions. Look in your tank for the 4 main types of algae—blue-green, red, brown, and green—and rank them from most prevalent to least prevalent. From here, focus most on the procedures that work on the most prevalent algae in your tank.[1]
- Blue-green algae thrive in general poor water conditions. They develop on your fish, which will eventually start to look moldy—especially when they’re motionless.
- Red algae are caused by a lack of carbon dioxide and hang all over your aquarium in threads.
- Brown algae thrive in conditions with a lack of adequate light and form in large, brown layers.
- Green algae are caused by too much light and can make your aquarium look like pea soup.
- 2 Boost carbon dioxide levels in your aquarium to starve red algae. Oxygen works to starve algae, which prevents them from growing. Invest in aeration devices such as airstones, bubble disks, and air pumps. This will boost carbon dioxide levels and even add give your fish some fun items to play with.

- Purchase carbon dioxide boosters from pet stores and online suppliers.
- 3 Decrease excess food to remove algae nutrition for blue-green and brown algae. Although fish need food to survive, too much leads to high ammonia and phosphate levels in your tank. The end result is often increased algae growth. Always stick to small portions of food that your fish can eat quickly to keep your tank clean and maintain a steady, effective feeding schedule. Ideally, you should feed your fish 1 to 2 times daily…
