My pond is spring fed, so I don’t need an aerator, right? | Ponds & Lakes Q&A

My pond is spring fed, so I don’t need an aerator, right?

Q: My pond is spring fed, so I don’t need an aerator, right?

Charles – Wadsworth, OH

A: Great question! First off, let’s tell the folks at home the differences between a catch basin pond and a spring-fed pond.

A catch basin pond is a reservoir filled with precipitation runoff—and pollution, in some cases—from the surrounding area. A spring-fed pond, however, is fed by a spring or ground water, which keeps the pond full. If you have cold areas of water in your pond, that could indicate that you have a spring-fed pond.

As the fresh water flows into the lake or pond from the underground aquifer, the water does move somewhat. But it doesn’t keep it agitated enough to naturally aerate it and maintain good water quality.

Preventing Thermocline

Whether you have a spring-fed or catch basin lake or pond, it’s critical to keep the water aerated. Why? Because doing so prevents thermocline, which is when the water forms layers, or stratifies, depending on the water temperature.

During the summer in a pond that’s not properly aerated, the water at the top is warmer and full of oxygen while the deeper water remains cooler and nutrient-rich. This phenomenon causes the fish to hang out at the pond’s surface. As the seasons change, however, the pond water does a “turnover,” which is where the warmer, oxygen-rich water sinks and the cooler, oxygen-depleted water to rise—leaving your fish gasping for breath.

Aerating Your Spring-Fed Pond

Obviously, you don’t want that to happen! So you should aerate your pond, even if it’s spring-fed. The action created by an aeration system, such as the Airmax® Pond Series™ Aeration System and the Airmax® Shallow Water Aeration System, effectively moves the water and causes the shallow and the deep water to mix. The Deep Water Aeration System is powerful enough to aerate ponds up to 3 acres and can be adapted to fit any shaped pond. The Shallow Water Aeration System is ideal for shallow lakes or ponds that require multiple aeration plates due to depth restrictions.

The result: oxygen is spread throughout the water column while dangerous gasses, like ammonia, are released at the water’s surface—and that means happy fish, good water quality and a healthy lake.

How can I prepare my aquatic plants for the fall and winter? | Decorative Ponds & Water Gardens Q & A

How can I prepare my aquatic plants for the fall and winter?

Q: How can I prepare my aquatic plants for the fall and winter?

Sandy – Holly, MI

A: This topic—what to do with your aquatic plants—tops the to-do list of many pond owners and water gardeners at this time of year. No matter the climate where you live, you will need to do some plant clean-up and relocate them to ensure they survive the winter frost and freeze.

What you need to do depends on the type of plant. So pull on your 28-inch, PVC Coralife® Aqua Gloves™ to protect your hands and arms and keep them dry, grab your handy-dandy Pond Scissors and Pliers, and let’s get to work! Here, we’ve outlined some basics:

Hardy Water Lilies

They may be “hardy,” but that doesn’t mean they’re indestructible! When the first frost hits in your area and the lily’s foliage begins to die back, trim the plant material back with your pond scissors to just above the root and toss it in your compost pile. Don’t worry: Come spring, the greenery will reemerge healthy as ever from the plant’s crown. Because water lilies are typically planted in frost-proof deep water, they will overwinter just fine.

Tropical Water Lilies

Tropical water lilies prefer warm temperatures all year long, so these colorful and fragrant beauties will need to be completely removed from your pond and relocated to a protected indoor space for the winter. We’ll talk more about how to overwinter these aquatic plants in future blogs.

Marginals and Bog Plants

As with hardy water lilies, your marginals’ and bog plants’ foliage will need to trimmed back with pond scissors and removed after Jack Frost first arrives. And if your iris, arrowhead, canna and other marginals are at or above water level, sink them lower into the pond where the water remains unfrozen during the wintertime.

Floating Plants

Unless you’re lucky enough to live in a climate that doesn’t freeze, floating plants like hyacinth and water lettuce won’t survive the winter. Plan to remove them from your pond to prevent the dead plants from decomposing and causing water quality issues through the wintertime.
