Tips on reducing pond algae and keeping your outdoor fish pond healthy

Regardless of the size of your fish pond, whether it’s a small outdoor pond in your back garden or a large stocked dam on your property, keeping it healthy and free from pond algae is essential. This is an ongoing process, however with a good pond cleaner, the right pond pumps and our quick tips below, you shouldn’t have any problems maintaining a healthy outdoor pond.

Clean your pond: If you find that the water in your pond is green or dark in colour and there is a layer of ‘muck’ on the bottom, then you might need to drain it and give it a good clean. In this case you will need to use a good strong pond pump to remove all the water (after catching the fish and keeping them safe). On the other hand, if there is just a small amount of natural debris that is easily removed using a simple pond cleaner (such as a net) and the water is nice and clear, then a quick clean might be all that is needed. If you do need to drain your pond to give it a good clean, it’s always best to do it during the cooler months, as warm weather will stir up the bacteria in your pond, causing it to look green, before it all settles down again.

Fix any leaks: A slow leak can seriously affect the health of your pond and your fish, particularly if you are always topping it up with tap water from the town supply. This tap water upsets the entire balance of your pond, so fixing any leaks is a sensible idea to the long-term health of your pond.

Check pond pumps: These are the heart of your pond, removing debris and keeping the water clean and healthy. If you don’t check your pond pumps, skimmer baskets and filters regularly, the entire system can back up with debris. A weekly check will keep your pumps operating smoothly and your pond looking clean, healthy and free from pond algae.

Control pond algae: Removing pond algae by hand is ideal in small backyard ponds and you might not need the addition of a chemical pond cleaner. Larger dams however, might require more mechanical or chemical solutions due to the increased volume of water. It’s also a good idea to regularly top up the healthy bacteria and plants in your pond, as these compete with the algae for nutrients, reducing the amount of pond algae you have to remove.
