  1. Filter maintenance: Make sure that it is working properly so that all harmful material is being filtered out of the water. Pond filters should be cleaned at least once a month to ensure they are working correctly and never leave it too long before cleaning out a clogged filter.
  2. Add plants: Plants will help keep your pond healthy by creating an environment that is beneficial for fish and can also help to clear the water. You can fertilise them, too. Just make sure to remove any dead plants and floating leaves.
  3. Cleaning: If your pond contains gravel, this should be cleaned at least once a year in order to remove any built-up waste or muck and keep the pump working properly. Try to use pond water to rinse the gravel, and if not then just fresh water.
  4. Testing: Regularly test for bacteria and ph levels with a kit, a healthy ph level is between 6.5 and 8.5.
  5. Be weather aware: Take steps to protect your pond and its inhabitants from the cold, such as adding a layer of insulation or using a heater.

Note that if you have fish in your pond, you may find you need to clean your pond water more often. It’s advisable to check the water on a weekly basis and take out any leftover food or waste promptly.

How to clear green pond water

It’s normal for ponds to get a bit cloudy every now and then, but if your pond water gets too murky or starts to smell, here’s how to get rid of algae in your pond.

how to clear green pond waterThere are a few easy steps you can take to clear green pond water:

  1. Try adding a bit of barley straw. It releases certain enzymes that collect free-floating algae and clump them together, causing them to sink. The downside is that it can take a few weeks for the barley straw to work, so you may need to be patient.
  2. If you don’t want to wait and you want to know how to clear green pond water fast, you can try using an algaecide. Be careful when using algaecides, as they can be harmful to fish and other pond life. Choose carefully and only use them if absolutely necessary.
  3. You can also try stirring up the water to make it less cloudy. This will help light to reach the bottom of the pond.
  4. Finally, you can add some plants to your pond. Plants are a very natural way of clearing green water, as they use photosynthesis to convert the energy from sunlight into oxygen that aerates your pond water. Pond weeds are particularly good for clearing green pond water.

How to keep pond water clear without a filter

If you’re wondering how to get rid of green algae in a pond naturally, these are some of the ways you can keep it looking crystal clear without a filter:

  • Add some plants. Pond plants help remove algae and excess nutrients from the water by taking them up through their roots. They are also a great option if you have fish in your pond, as they are completely natural, can be a food source and will provide shelter.
  • Add some barley straw to your pond, it collects algae and effectively transfers it the from the surface to the bottom of your pond.
  • Consider using an algaecide to break down the algae, but choose carefully and if you have fish or other aquatic life in the pond, always ensure the algaecide you use is safe for wildlife.
