Hair algae is a species of soft filamentous algae found in both fresh and saltwater that grows on everything that doesn’t move. If it overgrows, it can quickly become a nuisance and a health hazard, so to combat this you should introduce things into the environment that eat the algae.

How Do You Get Rid of Hair Algae?

Overpopulation of hair algae can create a huge mess in your pond or aquarium. Not only will it smother what it grows on, but it also takes up precious oxygen for the other things living in your pond as well.

Luckily, there are numerous ways to get rid of hair algae. There are many ways to combat the growth of hair algae, the easiest being to add fish or other aquatic life that eats algae. Here are some other things you can do to remove hair algae from your pond or aquarium:

  • Using algae treatments.

Is Hair Algae Bad?

Algae is caused by a deficiency of the nutrients in the water. It can be caused by a number of these imbalances and if it overgrows, it will become bad for your fish and the water.

Normally, having a little hair algae in your pond or aquarium is actually healthy because it provides food for the smaller aquatic life. But when it’s not kept back by something to eat it, the algae grows all over the pond and essentially ends up suffocating the whole environment.

Though hair algae doesn’t harm your fish directly, it does create an unstable environment for them to live in. As we’ve stated, it will essentially suck the air right out of the aquarium if there’s too much. This will result in decreased oxygen, which can be fatal to everything in the water.

Here’s what hair algae does to its aquatic environment, whether it’s a tank or pond:

  • Creates green, slimy-looking water
  • Smothers aquatic plants
  • Uses a lot of oxygen that your fish need

What Fish Will Eat Hair Algae?

What Snails Will Eat Hair Algae?

Snails are great at cleaning up the unwanted algae in any aquatic environment. In fact, you can find them in almost any natural body of water.

You may not have to add snails to a garden pond, since they’ll more than likely just show up themselves, similar to frogs and turtles. They usually make their way to your pond as eggs attached to birds, animals, and aquatic plants.

An important thing to remember is to never just catch snails from the wild. Freshwater snails are carriers of the deadliest parasitic diseases.
They can pass them to you and the fish they live with, so be sure to get your snails from a reputable aquarium or pond supply. If you need to handle them, it’s best to do so with gloves or try not to handle them at all.

Pond Snail Species That Eat Algae include:

  • Japanese Trapdoor Snails
  • Wandering Pond Snails
  • Great Pond Snails

Aquarium Snails that eat algae include:

  • Mystery Snails
  • Margarita Snails
  • Malaysian Trumpet Snails
  • Nerite Snails
  • Ramshorn Snails
  • Zebra and Mexican Turbo Snails

Another important thing to note is that when you’re introducing a new species to the pond, you will have to keep their population controlled as well. If there are too many snails, they’ll eat all the algae which is good, but then they’ll turn to the decorative aquatic plants that you don’t want to be eaten.
