Five Easy Tips for a Clean and Healthy Pond

Your pond is a beautiful ecosystem to a host of living things and you want to ensure that the habitat is healthy for the sake of both your fish and plants. Not to mention, a healthy pond with clean water is so much prettier to look at than a murky water garden.

Most pond owners are aware of the importance that good quality water plays in a pond habitat. But not knowing how to get or keep water quality can prove challenging to some pond owners.  We’re here to break the mystery down to five basic elements so you can rest assured your pond is in good hands.


1. The Right Pump for Your Pond

Pumps are the heart of any water feature, continually circulating water and providing aeration to create the basis for a stable ecosystem. Proper pump sizing is critical to the health and function of your water feature and you want to be sure you’ve selected the correct pump.

To provide optimal water quality, you want to circulate the entire pond’s water volume a minimum of once every hour.  If your pond contains 1,000 gallons of water, you need a pump that will push a minimum of 1,000 gallons per hour. Other variables come into play when choosing the proper pump, like the height of your waterfall and the length of pipe that runs from your pump to the waterfall.

Aquascape makes it easier to choose the right pump with our handy, online pond pump selection guide to make sure you’re using the right size pump for your pond needs.

2. A Balance of Filtration

A good biological filtration system, paired with a mechanical filter (such as a skimmer) to remove solids before the water enters the biological filtration unit, is the most effective way to filter water. Designing and implementing an efficient circulation and filtration system ensures that the water is oxygenated and pond debris (including leaves, floating algae, and anything else that’s blown in) will be swept from the pond’s surface and deposited into an easily emptied skimmer basket.

Aquascape healthy ponds incorporate a BioFalls® biological filter that serves as the start of the pond’s waterfall. The waterfall activity adds much-needed oxygen to the pond. Ideally, your skimmer should be placed on the opposite side of your pond. Aquascape skimmers provide room to house your pump, along with a basket that catches leaves and debris for easy clean-up.

3. Maintain a Healthy Fish Population

Pond owners love their fish and it’s easy to over-populate your pond – especially if your fish have babies!  Make sure you have no more than 10” of fish for every 100 gallons of water in your pond. You want to avoid excessive fish waste, which can cause an unhealthy imbalance in pond water. If you find yourself with an abundance of fish, consider finding a new home for some of your finned friends. Pond retailers and contractors might be willing to accept your fish. You can also contact local koi clubs.

One of the many joys of pond ownership is interacting with your fish. Many people train their koi to eat straight from their hands! However, when you feed fish more than they can eat, the uneaten food is left to decay in the pond. This can prove problematic to the quality of your pond water.  Be careful not to feed your fish more than once per day, and no more than they can eat in two to three minutes. Remove all excess, leftover food so it doesn’t deteriorate in your pond.

If you want happy and healthy pond fish, choose high-quality fish food such as those provided by Aquascape. We offer a variety of fish foods that contain probiotics to aid in digestion and reduce fish waste.

4. Create a Proper Balance of Plants

Plants absorb excess nutrients in the pond and help filter the water. In addition, plants like water lilies and water lettuce help to shade the pond and keep the water cooler during hot summer months. During the peak pond season, you want to ensure that 40% to 60% of the surface area of your pond is covered or shaded by plants. On the flip side, too many plants can cause oxygen deficiencies at night due to the photosynthetic process, when the plants take in oxygen and give off carbon dioxide.

You’ll enjoy the beauty provided by a wide range of pond plants, which fall into four basic categories.

Waterlilies are a favorite for the beautiful color they add to a pond. Hardy lilies return every year if properly over-wintered. Tropical waterlilies will die during winter months in most climates and are typically treated as annuals.  Marginal plants thrive in shallow water near the edges of the pond. They include both flowering and non-flowering options and help to soften rock edges while providing filtration benefits. Floating plants such as water lettuce and water hyacinth, float on the surface of the pond with their roots dangling in the water. Finally, oxygenators are planted at the bottom of the pond and help provide hiding places for fish.


5. Clean Debris from Pond Before It Decays

Decaying leaves and debris, combined with fish waste and leftover fish food, can cause ammonia levels to spike in your pond. High ammonia levels can stress your fish and cause illness. Be sure to remove dying leaves and plants, and remove uneaten fish food before it has a chance to decay. During the summer months, you shouldn’t find a lot of leaves and plant debris in your pond, but be sure to trim any dying leaves from aquatic plants.  During the fall season, install Aquascape Protective Pond Netting over your water feature before leaves begin to drop from the trees, to make leaf control easier. Beneficial microbes such as Aquascape Beneficial Bacteria can also be added to your pond on a continual basis to help keep pond water healthy and clean.


Enjoy Your Best Pond Ever

Following the above guidelines helps ensure that your pond is naturally balanced, thereby requiring less maintenance. When the water in a pond is murky and unattractive, it’s usually due to one (or more) of the previous tips not being followed. You’ll be surprised how easy it can be to enjoy clean and clear pond water throughout the season. And less work means more time you get to spend enjoying your beautiful water garden!
