Green, slimy, and gross – that’s how most people would describe green hair algae. This type of algae can be a nuisance in freshwater aquariums. If you’ve ever had to deal with hair algae, you know how frustrating it can be. But don’t worry; there are a few things you can do to get rid of this pesky green hair algae for good. In this article, we’ll discuss what hair algae are, what causes them, and how to get rid of them once and for all. We’ll also provide some tips on preventing hair algae from coming back in the future.
What Is Green Hair Algae?
Green hair algae is a type of algae that can grow on many surfaces, including rocks, plants, and glass. It gets its name from its long, thin, green strands that look like hair. Green hair algae can be aesthetically pleasing and annoying, depending on where it’s growing. In some cases, it can be harmful to plants and animals.
Green hair algae are usually not harmful to humans, but they can be unsightly if it’s growing on something you don’t want. In aquariums, green hair algae can quickly take over and start choking out other plants. It can also be challenging to remove once it’s established.
Once green hair algae have taken hold, the best way to remove it is physically. This means manually removing it from surfaces with a brush or other tool. You can also try using chemicals to kill the algae, but this can be difficult without harming other aquarium plants.
What Causes Green Hair Algae?
Just like other plants, green hair algae need water, light, and food to grow. Algae can grow like weeds in a tank when there are too much of any of these things. Read below to discover what causes green hair algae in your aquarium.
Too Much Light
Algae need light to grow, but if there is too much light, the green hair algae will grow too fast. If you have real plants in your aquarium, they will also need light to grow. But you can turn off the lights for a short time every day to help the green hair algae die back.
Overfeeding Your Fish
Fish waste contains the nutrients that green hair algae need to grow. If you feed your fish too much, it can cause green hair algae to grow. You should only give your fish what they can eat in a few minutes.
Not Enough Filtration
Filtration is needed in aquariums to get rid of waste and poisons in the water. However, filters can also eliminate snails and shrimp that eat green hair algae. Green hair algae will have more chances to grow if you don’t have enough filtration.
Aquarium Gets Direct Sunlight
Green hair algae need sunlight to grow, just like any other plant. If you put your aquarium in a room with a lot of direct sunlight, green hair algae will grow there. You can either move the aquarium to a different spot or put a curtain over the tank to block out the light.
Too Many Fish in the Tank
With more fish comes more waste, which can cause green hair algae to grow in large numbers. You should have the right number of fish for the size of your aquarium. One inch of fish per gallon of water is a good rule of thumb.
Aquariums with a pH that is too high or too low often have green hair algae growing in them. If your pH isn’t in this range, you’ll have to change it. A pH test kit can be used to check the pH of your aquarium.
Overdue Water Changes
Aquarium water needs to be changed often to eliminate waste and toxins. If the water isn’t changed often enough, green hair algae can grow in it. As a general rule, you should change 10-15% of the water every week.
How To Get Rid Of Green Hair Algae
Green hair algae grow quickly and can take over your tank in a few days. It makes your plants die, it can trap your fish, and it just looks bad. It’s something nobody wants, but how do you get rid of it? Below are 7 ways how:
1. Manual Removal
Green hair algae are easy to get rid of because it is soft and doesn’t stick to things very well. Use a toothbrush, a small bottle brush, or pipe cleaner and twist the strands on the brush before pulling them up and out of your tank. If the green hair algae are growing on a loose piece of hardscape, like a rock, you can take it out and clean it in a separate water container.
2. Add More Plants
In a planted aquarium, all the plants and algae are actually competing for the same food and water. Once you know this simple fact, it’s easy to see how healthy plants can be such an excellent tool for fighting green hair algae! Adding more aquatic plants, especially ones with stems that grow quickly, can starve green hair algae and make it die off on its own.
3. Improve Your Water Source
The water is what makes an aquarium. It is the base of the whole system, so it is usually the first place to look when green hair algae problems start. Check to see if your water source has more of the silicates, nitrates, and phosphates that green hair algae eat.
4. Improve Your Water Parameters
To keep the water quality high, it is very important to test it often and change some of it. Some nutrients, like nitrates and phosphates, can cause hair algae to grow in an aquarium that is not well taken care of. But plants and even corals need these nutrients to stay alive, so regular maintenance is the best way to keep the concentrations at a safe level.
5. Use an Algae Eater
Many different types of algae eaters can help control green hair algae in your aquarium. Some, like the Siamese Algae Eater, will only eat certain types of algae. But others, like the Black Molly, will eat just about anything!
6. Use a UV Sterilizer
Using a UV sterilizer is a great way to control green hair algae and many other types of algae in your aquarium. UV light can kill the algae cells, preventing them from reproducing.
7. Use Chemical Treatments
If all else fails, you can always use chemical treatments to get rid of green hair algae. Many different products on the market will kill green hair algae, but you need to be careful not to kill all the algae in your aquarium. Some products will only kill certain types of algae, so make sure you read the labels carefully.

The whiptail catfish eats everything, so in addition to green hair algae, it will also eat things like fish food that haven’t been eaten. These fish have neutral colors like black and tan, and they can grow up to 6 inches long, so they need a tank that can hold at least 50 gallons.
