What Can Cause Algae To Form In Ponds

  • Something in the filters or pumps may not be working
  • You may have too many fish creating waste for your filters
  • Too much debris is breaking down in your pond, which feeds algae
  • You don’t have enough filters, which allows excess nutrients to gather
  • There isn’t enough aeration, which oxygenates the water
  • Your pond gets too much sunlight, encouraging algae growth

How To Treat Algae In A Pond

To treat algae in a pond, the first step is to troubleshoot your pond. It could be that something isn’t working right, allowing algae to grow. You can use algae treatments, put living filters in your pond, install more mechanical filters, and add rocks and gravel.

1. Troubleshooting Your Pond

When something seems off with your pond it’s likely that something isn’t working correctly.

Filters might need checking, pumps might not be working too well, a part of your pond is letting rainwater runoff in, or it just might need a cleaning.

Troubleshooting a pond is tough. You’re on your hands and knees, moving rocks and dirt around, bending over, and it’s all outside. Most people hire someone to do this for them because it’s tiring and takes a practiced eye.

2. Using Algae Treatments

You can always skip the organic treatments and go right to chemicals.

There are ones safe for animals and plants (we highly recommend this). They’re great for getting rid of algae, but not solving the cause. They bind algae together for easier removal.

AlgaeFix, Greenclean, and Sludge Remover Bacteria are 3 good choices.

3. Getting Living Filters

These include fish, plants, and beneficial bacteria.

Koi like eating algae, it’s like a snack for them. They also add fun energy to your pond and you can feed them! Be aware, if your filter can’t handle the amount of waste they create algae can start growing too fast.

Plants eat the nutrients algae use to grow. They can also aerate the water, block sunlight, and beautify your pond.

Beneficial bacteria live in biofalls filters and on rocks and gravel. They take up nutrients in the water that algae feed on. They also eat muck and debris.
