3 Things You Can Do To Keep Your Pond From Green Algae

Use Barley Straw

If you are a pond owner, it’s likely that at some point, you will have to deal with the problem of green algae. However, there are several things you can do to prevent it from happening or to clear it up if it does happen. One of the most effective products for this is barley straw.

Barley straw is an all-natural product that not only helps prevent green algae from forming but also helps keep your pond water clean and clear. It starts working in about 4-6 weeks and lasts for about six months per bale. You can use barley straw by putting a piece into a nylon stocking and hanging it in your pond or by spreading flakes of barley straw on top of your water. If you have plants in your pond, consider using one method versus the other so as not to harm them.

Plant Aquatic Plants

Plants are the easiest way to prevent algae. They take in nutrients and carbon dioxide, release oxygen and help to keep your pond water healthy. They provide habitat for fish and other critters that live in or near your pond too.

Plants will compete with algae for the same resources such as sunlight, so this helps keep algae at bay. You can get aquatic plants from most garden centers or online. You need about 1 square foot of plants for every 10 gallons of water in the pond. Plant them close to the side of your pond so that they don’t float off after a heavy rainstorm or if you turn on the waterfall feature. They normally start growing right away, but if they don’t, it’s probably because they’ve been sitting around on a shelf in a store somewhere and are not capable of growth anymore as they’re no longer gently wrapped around wet rocks covered by water like they would be in their natural environment. In this case you’ll want to get new ones that aren’t dead yet (see below)

It’s important to prune aquatic plants regularly throughout the season to keep them healthy and looking good. If you have too many plants it will make it difficult for your fish (and other living things) to swim through them! You can trim off any unwanted growth with scissors or by cutting off an extra pot when you repot one of your plants each year (more information below).

If you’re feeling especially ambitious then try planting some terrestrial plants on top of your soil mixture at different depths within their pots—this way there is more room for roots so each plant can grow larger than normal!

Add Fish That Eat Algae

Add Fish That Eat Algae

Live fish are a great way to control the growth of green algae in your pond. There are several kinds of fish that eat algae and make for beautiful additions to your pond. If you have a large pond or lake, koi fish are a good choice because they can handle the often colder temperatures involved with larger bodies of water.

If you have a small pond or lake, goldfish are another good choice because they can be kept in smaller groups due to the smaller size of their bodies of water. Butterfly koi is another kind of fish that will eat algae if you have a large body of water.

There are multiple all-natural and effective ways to keep your pond from green algae.

Good news! You can keep green algae from overtaking your pond. As the saying goes, prevention is the best medicine.

There are many ways to keep your pond from green algae, but these three have proven to be most effective:

  • Water testing kits will allow you to see what’s going on with your pond water and what nutrients or chemicals need to be added or adjusted in order for it to become healthy again. Once you know what exactly is going on in the pond, you can take steps that will get rid of the algae and prevent more algae growth in the future.
  • Adding goldfish may not sound like an all-natural solution, but they are very effective at controlling algae levels, especially if you add a couple hundred fish into a small pond. They do this by eating and breaking up algae in all different areas of the pond instead of just one place where a bubbler or fountains would be targeting, allowing them to cover a lot more ground than other methods. The goldfish will eat so much that they might even require additional food throughout the day, so don’t forget about them!
  • If you don’t have time for regular upkeep and maintenance due to work or other commitments, then selling your house might be worth considering because you have very little time for anything else anyway. Make sure that this move is financially feasible before taking any action though.

Ponds are great—they add an element of natural beauty to your backyard, and they’re a great way to attract birds and other wildlife. But they can also be high-maintenance, especially if you’re dealing with algae blooms that make the water look green.

We get it—you want to enjoy your pond, not spend all your time maintaining it, so we’ve put together this list of 3 things you can do to keep your pond from green algae.

1) Keep It Clean

Regularly cleaning the surface and bottom of your pond is one of the best ways to prevent algae growth. You can use a net or skimming device designed for ponds, or simply scoop up any plant matter floating on the surface with a bucket. If you have fish in your pond, they’ll clean some of the surface on their own, but they won’t be able to reach anything at the bottom, and they generally won’t eat green algae.

2) Use A Natural Pond Cleaner

While there are plenty of algaecides out there that will kill algae in your pond, many of them have chemicals that can harm other plants and animals like fish or frogs. Instead of killing the algae, you may want to consider using a natural product that

Summer is here and the weather is beautiful. Ponds are a great addition to any garden, but when you have one, you have to keep an eye on the water.

This is because green algae can be a problem for your pond. Fortunately, there are some things you can do to stop algae from taking over your pond.

Here are three things that you can do to keep your pond from green algae:

1. Get a fountain – If your pond doesn’t have a fountain, then it’s time to get one. Fountains make the water circulate so it doesn’t get stagnant. A fountain will also help prevent algae from growing in your pond by keeping the water moving. This is important during the summer months when temperatures rise and sunlight increases, making it easier for algae to grow in your pond’s water.

2. Use a UV clarifier – The sun is what makes algae grow, so having a UV clarifier will help keep it out of the water and make sure that it doesn’t get into your pond’s filter system or pump. The UV clarifier will also help keep other impurities from getting into the water as well as keeping it clean and clear so there aren’t any issues with bacteria growth or other problems that could come about

Green water in your pond is ugly, and it can be harmful to the health of your fish.

Luckily there are three simple things you can do to prevent green algae from taking over your pond.

Add Plants

First, you should add more plants to your water garden. Algae growth is stimulated by sunlight and nutrients in the water. Adding plants to the pond helps shade the water, reducing exposure to sunlight and keeping the waters cooler. Water temperatures below 80°F slow down algae growth, while warmer temperatures cause it to bloom.

Plants also use nutrients in the water, leaving less available for algae growth. Plants also provide oxygen as a part of their natural photosynthesis cycle—this oxygen is vital for your fish’s health and well-being!

Use Pond Dye

The second thing you can do is use pond dye on your lake or pond. Dyeing your lake or pond doesn’t just make it look pretty—it actually reduces algae growth by reducing light penetration. Algae needs sunlight to grow, so if you cut off its light source it will die off naturally. This can also help prevent green water from returning in the future because algae will never get a chance to regenerate!

Use A Green Water Treatment

Third, use a treatment

Green algae is the bane of many pond owners. If you have a pond, then you probably know what I’m talking about. There’s nothing that can dampen your enthusiasm for a beautiful pond like seeing it covered in a layer of green slime.

Don’t worry! We’re here to help. Here are three things you can do to keep algae from taking over your pond:

-Test Your Water For Nitrates

Algae uses nitrates as fuel, so the more nitrates there are in the water, the more algae will grow. This makes nitrate levels a good surface-level indicator of how much algae is growing in your pond. You can test your water yourself with the [product name] water testing kit, or you can bring samples to a local garden supply store and have them test it for you.

-Remove Excess Fertilizer From Your Yard

If you use fertilizer on your yard, it’s likely that some of this fertilizer seeps into your pond and feeds any existing algae. If your water testing kit indicates high nitrate levels, consider removing any excess fertilizer from your yard and see if this lowers the amount of algae in your pond over time.

-Treat Your Pond With [product name]


If you’re pond owner, you know how much of a pain it can be when algae blooms and starts to take over your pond.

Finding the right balance of plants, fish, water and sunlight can be tricky, but if you want to keep your pond from looking like a swamp, it’s important that you get it right.

Fortunately, dealing with an algae bloom isn’t impossible. Here are three things that you can do to keep your pond clear:

Keeping your pond from turning green can be a challenge. Between the changing seasons, the elements, and your fish, it’s tough to keep your pond safe from algae. But there is hope! Here are some tips for keeping algae out of your pond:

1) Keep your fish population at a healthy level. Overpopulation leads to more waste in the water and less oxygen—a perfect breeding ground for algae.

2) Use a UV-C clarifier. This is one of the most effective ways to kill off free-floating algae and prevent them from infecting other areas of your pond or tank.

3) Make sure there’s plenty of plants in the pond. Plants are natural competitors with algae for nutrients in the water, so they will help keep it clear and clean.

Good luck!
