Fish are survivors. And when the water starts getting cold, they head for deeper waters, where the chilling effects of winter air are less pronounced. Provided there’s adequate aeration, your fish will likely linger at the bottom throughout the colder months. As a result, they’ll be much less visible – but the odds are extremely good they’re doing just fine.

In order to ensure there’s sufficient oxygen for the winter, some people opt to keep their aeration systems active all year ‘round. At the very least, though, it’s important to maintain a vent hole when – or if – your pond ices over. The vent hole allows harmful decomposition gases to escape, allowing fish to winter safely. And because their metabolism slows during the winter months, a properly vented pond will likely have sufficient oxygen to ensure the survival of your fish until springtime.

Fish, it turns out, are extremely resilient. After wintering in the lower reaches of your pond, your fish will gradually return to the upper levels once water temperatures start to rise. In general, it’s probably a good sign when fish become less visible. If they’re struggling, it’s far more likely you’d see them at the edges of your pond. So while you might miss them, your invisible fish are probably doing just fine.

What happens to the frogs and toads during the winter? | Pond & Lake Q&A

When should I remove the fountain from my pond?

What happens to the frogs and toads during the winter?
Dustin – Huntsville, UT

As the temperatures continue to drop you will begin to notice that your pond, once full of life, is now starting to look like abandoned arctic tundra. Gone are the cool summer nights spent on your patio and deck watching fireflies tastefully illuminate your lawn while being serenaded by a choir of frogs and crickets.

While you are inside cuddled under blankets for the season where do your web-footed friends spend their winter? The winter retreat of choice will depend on the type of frog you have hanging around your pond. You will commonly find either some variety of frog frequenting the shallow areas or shoreline of your pond and toads farther inland rummaging about your gardens or front lawn. Both are very similar but can usually be identified by a few visual characteristics. Frogs tend to have smooth glossy skin that feels slimy to the touch while toads have dry lumpy skin. The eyes of a frog tend to protrude further from its head than those of a toad. A toad will usually have poison sacks located behind their eyes which help prevent them from becoming a snack for larger predators.

As frogs are cold blooded they will begin to slow down as their body temperatures drop. When winter arrives they will go into a state of dormancy and wait out the cold weather. The hibernation strategy varies between species of frogs. Toads tend to bury themselves in leaves or mud while frogs can pass the winter at the bottom of your pond below the ice. Frogs produce a type of glucose in their bodies that will allow them to freeze solid and still be able to survive. As the temperatures begin to rise in the spring their hearts will begin to beat again and they will begin to thaw. When they are once again mobile they will actively search for a place to mate.

Since frogs have an arsenal of survival skills to get them through the winter there is not much you have to do to help them survive the cooler months. Instead focus on keeping yourself warm and healthy and try your best to enjoy the snow and beautiful landscapes this winter brings

In bacteria paradise, the temperature in your backyard pond would never fall below 50 degrees Fahrenheit. When water temperatures drop below 50 for any sustained period of time, the bacteria call it quits for the season.

But just because you’ve been feeling the cold for a few days, remember: it takes water longer to respond to changing temperatures. Thus, when it’s below 50 degrees outside for a lengthy stretch, your pond water may not have fallen as far – and your bacteria may be doing just fine. To get the most accurate reading you can, consider buying our Pond Logic® Floating Pond Thermometer. It’ll give you up-to-the minute readings, making it easy to monitor the health of – and the need for – your favorite bacteria.

When your pond is still in the above-50 degree range, we strongly recommend the continued use of Pond Logic® PondClear™ Beneficial Bacteria, and Pond Logic® MuckAway™ Pond Muck Reducer. These two products help to maintain healthy bacteria levels in your pond, which will help to reduce organics, excess nutrients and noxious odors, while breaking down muck and keeping your pond water clear.

Once your pond water drops below 50 degrees, you can safely suspend bacteria treatments. But when the temperatures start to rise again in the spring, be prepared to start back up – and get your pond water in great shape for another season.

When fall comes around, leaves and ponds seem to have a magnetic attraction to one another. And while netting is available in essentially any size you might need, it’s a cumbersome solution for larger ponds. Simply spreading the netting over a large pond is a major undertaking – and the impracticality of installing posts throughout your pond to keep leaf-covered netting from sinking makes other solutions look much more attractive.

At The Pond Guy, we strongly recommend aeration and chemical treatments to address inevitable leaf buildup for customers with large ponds. When you browse our web site, you’ll notice a wide range of Airmax® Aeration products. These aeration systems enable the pond to break down leaves quickly and naturally by keeping pond water moving – and the entire pond well oxygenated. When coupled with the beneficial bacteria in PondClear™, EcoBoost™ and MuckAway™, fallen leaves break down in no time to keep water clear, and both fish and plants healthy.

As an added measure in the fight against falling leaves and debris, you should also consider the use of a pond rake. With the regular use of our Pond & Beach Rake, you can easily remove excessive leaves and debris in no time flat.

It is not uncommon for ponds to get a little out of control as the temperatures begin to drop in the late fall and early spring. As water temperatures decrease, your pond crosses a balancing point where your bacteria and algaecides can no longer remain effective enough to fight off excess nutrients and cold temperature plant growth. Customers tend to let their guard down at the end of the season as they venture indoors for the winter.

Pond dye is an effective year-round treatment that works flawlessly in the winter giving your pond a unique look even as it ices over. Algae and plants can still grow at the bottom of the pond in cold temperatures and they are continually exposed to sunlight even if there is a layer of ice on the pond. There are multiple shades of dye available to pond owners. Pond Logic® offers pond dye in a decorative Nature’s Blue™, natural blue-green Twilight Blue™, or reflective Black DyeMond™, so you can achieve a unique color that fits your particular setting. You can learn more about choosing the best pond color in our Pond Dye Blog.

Organic matter will continue to decay during the winter, and run off from melting snow and rain will contribute to an increase in phosphate levels which encourages algae growth. Using a water conditioner like Pond Logic® EcoBoost™ will continue to bind these phosphates rendering them useless to weeds and algae as well as introduce trace minerals into the water column which promote a healthier fish population. EcoBoost™ also enhances the natural bacteria found in your pond increasing their productivity when they are active.

Both EcoBoost™ and pond dye are considered “proactive” pond care treatments as they are designed to create a balanced ecosystem and prevent problems like algae growth or turbid water. You can save yourself a lot of work and money on difficult spring start ups or late season algae blooms by continuing to use these types of pond care products throughout the year even after your bacteria and herbicides are packed away for the winter.

How do weeds like Cattails and Phragmites survive the winter? – Ponds & Lakes Q & A

How do weeds like Cattails and Phragmites survive the winter?

How do weeds like Cattails and Phragmites survive the winter?
Bryce – Grand Rapids, MN

Your gamefish and frogs aren’t the only ones hiding from the cold winter weather. Even your emergent weeds have developed a defense mechanism to survive over the winter. Being perennial plants, they may appear to die when the weather cools down but they are really just buying time until the spring thaw when they will return in all of their glory. Whether or not this is good news depends on how you feel about the presence of these particular plants in your pond.

Plants like Cattails tend to disperse their seeds as fall approaches. As the weather continues to cool the leaves and the stalk of the plant wilt and die only to decompose and become fertilizer for the roots, or rhizomes, of the plant come spring. While the exposed areas of the plant are dying off, the roots of the plant begin pulling in nutrients to store before going into dormancy for the winter. As these roots can be considered the heart of the plant, cutting down Cattail and Phragmite reeds will not discourage new plant growth in the spring.

If you like having Cattails or Phragmites around your pond then nothing is needed to help them through the winter as they are naturally prepared to make a comeback. If you are not a fan of these emergent plants you can make it harder for them to grow back by physically removing the plant roots or by using pond care products to remove their food source and kill the plants including the roots. Applying aquatic herbicides like Shoreline Defense® while Cattails and Phragmites are still active is infinitely easier than trying to pull their extensive root system from the pond. Shoreline Defense® is absorbed by the plant and carried to its roots effectively killing the entire weed. Since you don’t want to encourage new growth you will want to remove any potential “fertilizers” in the form of plant decay and muck. Once dead cut and drag any dead reeds and leaves away from the pond and burn or compost them. Using a Rake and Weed Cutter will make short work of these shoreline cleanups and give you the advantage for next season.

How do fish go dormant? Are they really asleep? – Decorative Water Gardens Q & A

With the warm days of summer now a distant memory and fall following in its footsteps your Koi are left with a few months of cold weather with nothing to do but relax. Since they don’t have miniature submerged Koi calendars to check what is it that tells your fish it is time to hibernate?

Koi are cold blooded creatures which means their body temperatures and activity levels are directly correlated with the ambient temperature. Koi are active and alert when their environment is warm and will start to slow down as the water temperature decreases. Once the water temperatures start to dip below 46°F your fish tend to stop eating and will retreat to the bottom of the pond. Your fish use the decrease in temperature along with the shortening day lengths as a trigger to prepare for winter. As the water begins to cool your fish will become less active as their bodily functions slow down. Less activity means a slower digestive process, less demand for food. It is this decrease in food digestion that warrants the use of wheat germ based foods like Pond Logic® Spring & Fall Fish Food. These types of food are easier to digest that regular food reducing the risk of leaving undigested food to rot inside a dormant fish which can potentially be fatal.

As the temperatures continue to decline towards 40°F, the blood flow and respiratory rate of the fish will drop to an extremely low rate where their body is hardly functioning. You may hear people say that your Koi are sleeping in the winter and while fish do sleep this goes way beyond the standard drop in bodily functions associated with some much needed shut-eye. This extreme internal slow down ensure survival with even the most limited resources with cases of dormant fish lasting 150 days without food.

The whole over-wintering scenario sounds a little extreme to us but it is truly a natural and normal process for your fish. They do not require much attention in the winter but there are a few things you can do to ensure their winter break is a success. When a layer of ice begins to form over the pond, maintain an opening for gas exchange using your aerator or a de-icer. Also, make sure you feed with a cold weather formulated fish food as water temperatures approach 50° so your fish are able to safely digest it before hibernation begins. You can use a pond thermometer to keep track of the water temperature in your water garden.
