Q: I am bringing my fish inside for the winter. What do I need?

Carol – Afton, MN

A: In last week’s blog, we talked about how deep your pond needs to be to overwinter your fish outdoors. As promised, this week we’ll talk about what to do if your pond is less than 18 inches deep or you think your temperatures are too cold outside for your finned friends.

Bring ‘m Inside!
Do you have a pole barn? A garage? A basement? An unused outbuilding? These places make perfect indoor places to overwinter your fish. Koi and goldfish begin their wintertime dormancy at about 45 degrees Fahrenheit, so it’s best to choose a space that hovers at about this temperature or below.

The Gear
To prepare your fishes’ winter home, you’ll need some special supplies, including:

  • Stock Tank or Holding Tank: This will be your indoor pond area. Because your fish will be dormant they won’t need a huge pond to live in, so you can get away with smaller quarters. Choose a tank that’s sized appropriately for the number and size of your fish. To make the transition easier, use a siphon to fill the holding tank with water from your pond.
  • Pond Netting: The close quarters might surprise your fish and they could try to make a jump for it, so make sure you cover the tank with The Pond Guy® Premium Pond Netting and secure it with bungee cords or other tie-downs. That will keep them safe and secure.
  • Aeration System: Just as you aerate your water garden, you’ll need to aerate your holding tank to keep the water oxygenated. An energy-efficient PondAir™ Aeration Kit will work in setups up to 2,000 gallons; a KoiAir™ Aeration System will work in larger setups with more fish.
  • Filter: If your region is warmer, you might consider adding a ClearSolution™ Filtration System (for setups less than 1,200 gallons) or AllClear™ Pressurized Filter (for larger setups) to keep your water clear and your fish healthy.

Wintertime Chores
Caring for your fish in their indoor digs is similar to what you do when they’re outside. Because the living quarters are cramped, check your water parameters with a test kit once a week or so to ensure the water quality is safe. Also, check you water levels and add water as needed, and keep an eye on the equipment to make sure it’s working properly.

Other than that, your fish should be just fine through the winter. Once spring rolls around and water temperatures warm up, they’ll be ready to stretch their fins!

Jessica – Hope Valley, RI

A: Great news! Unless you live in an extremely frigid climate, your pond is at the minimum depth required for overwintering fish in a pond. Though 24 inches or deeper is better, 18 inches should give your finned friends enough room to ride out the cold temperatures—as long as you keep a hole open in the ice.

Freezing winter temperatures will create a solid layer of ice on your pond’s surface. Below the ice sheet, decaying vegetation and organic matter release harmful gases, like ammonia, which can build up and kill your fish. A hole in the ice will allow for gas exchange. The oxygen will enter the pond, the gases will escape, and your fish will stay happy and healthy while they’re hibernating.

To keep that hole open, here’s what you’ll need based on your zone:

  • Occasional Below-Freezing Temps: For temperature zones that get the occasional below-freezing day or low nighttime temperatures, use an adjustable air stone aerator, like the Airmax® PondAir™ (up to 2,000 gallons) or Airmax® KoiAir™ (up to 16,000 gallons). One of these units will infuse your pond with oxygen while remaining quiet and cost-effective.
  • Long Stretches of Freezing Temps: For temperature zones that see long stretches of freezing temperatures, we recommend these options, below, based on how many gallons your pond holds. The aerator-deicer combo will give your smaller water garden the one-two punch it needs to vent harmful gases and keep your fish safe, while the more powerful KoiAir will sufficiently aerate larger ponds:

Do I need a heater to overwinter my fish in the pond? | Decorative Ponds & Water Gardens Q & A

Q: Do I need a heater to overwinter my fish in the pond?

Q: Do I need a heater to overwinter my fish in the pond?

Pat – Far Hills, NJ

A: Unless you house warm-water fish like Plecostomus in your water feature, you won’t need a heater to heat things up. Most pond fishes, including koi and goldfish, will overwinter just fine in their outdoor digs because they go into a pseudo-hibernation state when water temperatures fall. Their metabolisms slow and they’re able to tolerate cooler water—even water that’s frigid enough to freeze.

If you live in a climate that experience those freezing temperatures, what we recommend is a de-icer or aerator (rather than a heater) to keep a hole in the ice. This hole allows for gas exchange, through which necessary gases like oxygen enter and harmful gases like ammonia escape.

Which option is right for you?

  • De-Icer: A de-icer’s purpose is to float on the surface and melt a hole in ice that has formed on a container of water, whether a koi pond or water garden. Unlike a heater that actually warms the entire body of water, a de-icer like the K&H™ Thermo-Pond 3.0 Pond De-Icer simply melts an opening in the ice sheet, thereby allowing for gas exchange.
  • Aerator: Rather than create a hole in the ice from above, an aerator, like the PondAir™ Aeration Kit, circulates the water below the ice sheet. In areas with relatively mild winters, that subsurface water movement will keep a hole in the ice that allows for gas exchange—but when temps really dip, an aerator may not be enough to maintain a vent hole.
  • De-Icer, Aerator Combo: An excellent and convenient option to consider is the PondAir™ & Thermo-Pond Combo. It combines both the Thermo-Pond and PondAir™ Aeration Kit, providing your water feature the one-two punch it needs to stay well-vented throughout the winter.

If temperatures in your area vary between above- and below-freezing, consider installing a ThermoCube®. The thermostatically controlled outlet turns on when air temperatures drop below 35° Fahrenheit and turns off when air temps rise above 45°F. This handy-dandy device will save you money, which is something we can all appreciate!

Fall is just around the corner. What kind of prep work should I be doing now? | Decorative Ponds & Water Gardens Q & A

Q: Fall is just around the corner. What kind of prep work should I be doing now?

Karen – McHenry, IL

A: Though we all wish summer could linger on forever, the reality of fall—and its associated pond chores—is nearly upon us. Cooler temperatures, shorter days and those brightly colored (and falling) leaves means you need to take a break from summer fun and get to work.

Here’s a quick rundown of the prep work you should be doing now:

Add Bacteria

When temps start to fall (particularly below 50°F), it’s time to add some cool-water beneficial bacteria to your pond, like the tiny muck-eaters in Pond Logic® Seasonal Defense®. They go to work decomposing leaves, scum and sediment that will inevitably build up over the fall and winter, which will result in better water quality for your finned friends.

Clean Up Your Plants

Cut back and remove any dead plant vegetation that’s inside and around your water garden. Use a handy long-reach tool, like the Pond Scissors and Pliers, to cut back water lilies and clear away dead marginals. As the temperatures cool even more, you’ll need to remove floating plants like hyacinth and water lettuce, sink your hardy water lilies and marginals into the deeper areas of your pond to protect them from freezing, and make plans to overwinter your tropical lilies inside.

Cover Up

Blowing leaves and other debris will drop into your pond during the fall, and if you don’t get them out, they’ll decompose over the winter and create a mucky mess in the spring. Plan to put a net over the pond, like the The Pond Guy® PondShelter™ Net Kit, to keep them out, and use a skimmer net to remove any stragglers.

Have Supplies Ready

While you’re thinking about fall, now is a great time to stock up on winter water garden supplies. Purchase a six-month supply of Seasonal Defense®. Buy some Spring & Fall Fish Food, which will help your fish transition from their regular diet to one that’s easier to digest in cooler temperatures. Make sure you have an aerator or deicer ready to keep a hole in the ice. Preparing ahead of time will prevent any last-minute scrambling.

Regular Maintenance

Finally, continue to perform regular maintenance chores, like keeping your filter clean and operating well, doing periodic water changes, and feeding and checking on your fish. Summer is nearly over, but don’t neglect your pond-keeping routine!

What is the optimum water temperature for my pond, and when should I worry that it’s too hot? | Decorative Ponds & Water Gardens Q & A

Q: What is the optimum water temperature for my pond, and when should I worry that it’s too hot?

Q: What is the optimum water temperature for my pond, and when should I worry that it’s too hot?

Gayle – Syracuse, NY

A: “Room temperature” isn’t just for humans. Fish and pond critters prefer particular underwater temperatures, too. In fact, and a high-temp living environment can even affect their health and well-being. Warm water holds less oxygen than cool water, so they’ll be literally gasping for breath if it gets too hot.

As the air temperature heats up this summer, the water temperature in your pond will increase, too, so it’s critical to keep an eye on it as the mercury rises. Use your Floating Pond Thermometer to test the waters. The best water temperature for your aquatic pals is between 68° and 74° Fahrenheit (pretty close to an ideal air temperature for humans).

If your thermometer tops 85°F, you’ll need to cool your water. Here’s what we recommend:

  • Add Aeration:Make sure you have your aeration system, like the Airmax® PondAir™ or KoiAir™ Aeration System, up and running. It’s like an underwater fan for your koi and goldfish. The moving, bubbling water is cooler and loaded with oxygen, making it easier for your fish to breathe.
  • Add Plants: Just as you seek out shady spots to shield yourself from the sun’s rays, fish will do the same to keep themselves cool. Make sure that about 60 percent of your pond’s surface is covered with floating plants, water lilies and other types of shade cover for your pond pets.
  • Add Water: Warmer temperatures mean increased evaporation rates, so make sure you top off your pond during hot weather. Doing so isn’t a substitute for a water change, but it will cool off the water and ensure your finned friends have enough wet stuff in their pond.

One last tip: Do not feed your fish when water temperatures are above 85°F. They probably won’t be hungry. And besides, the uneaten food will just ruin your water quality.

My fish hang out near my waterfall during hot days. Do I have enough aeration in my pond? | Decorative Ponds & Water Gardens Q & A

Q: My fish hang out near my waterfall during hot days. Do I have enough aeration in my pond?

Q: My fish hang out near my waterfall during hot days. Do I have enough aeration in my pond?

Amanda – Rowlett, TX

A: On hot days, who wouldn’t want to hang out near a waterfall! For humans, the water pouring into the pond cools and hydrates the air; for fish, that action acts as a giant aeration system, infusing oxygen into the water beneath the waterfall.

But that raises a valid question: If your fish spend a lot of time near the waterfall, does it mean they’re not getting enough oxygen? Yes, it’s possible. Here are some questions to ask yourself about your pond’s aeration situation.

Is It Getting Full Aeration?

If you’re running your waterfall 24 hours a day, your pond is likely getting full aeration. If your pond is more than 24 inches deep, however, and you have a skimmer/waterfall system in place, more aeration may be necessary. Why? Because the oxygenated water will circulate across the water surface, leaving the water at the bottom of the pond stagnant. Adding an aeration system will prevent stagnation by raising the bottom water to the surface.

Do You Have Many Plants?

Plants may release subsurface oxygen to the water during the day, but at night those plants take in oxygen, which means your fish may be gasping for air. If you have quite a few plants and your waterfall is off—and you experience an algae bloom—you should definitely think about adding some aeration.

Do You Have Many Fish?

The more fish in your pond, the more oxygen you’ll need—which means you’ll need more aeration. If your pond has a high fish population, consider adding some more aeration. For comparison, we recommend one 6- to 8-inch fish per 10 square feet of surface area.

How’s Your Muck Level?

Another clue that your pond is insufficiently aerated is the amount of muck that has accumulated at the bottom of your pond. When your pond is properly aerated, muck naturally breaks up thanks to the healthy and growing population of gunk-gobbling beneficial bacteria.

Low-Cost Aeration

If any of these scenarios apply to your pond, we recommend adding the energy-efficient Airmax® PondAir™ Aeration System for ponds up to 2,000 gallons or the Airmax® KoiAir™ Aeration System for ponds up to 16,000 gallons. They help to circulate the water and add valuable oxygen, providing the best possible environment for your fish.

Q: When should I take the aerator out of my water garden?

Peter – Townsend, DE

A: You gotta love your aerator. This valuable wintertime tool not only keeps a hole in the ice for gas exchange, but it also circulates the water beneath the ice. Your Airmax® PondAir™ Aeration System keeps your fish happy and healthy through the icy winter months.

As springtime approaches and you notice that the ice covering your pond starts to recede, your fish may become more active. This indicates that your finned friends are no longer under threat from trapped gas—so it’s logical to assume you can remove the aerator, right?

Not so fast.

Mother Nature has a way of teasing us with spring sunshine, so don’t get too excited. In most places across the continent, it’s still cold and your pond’s ecosystem will remain dormant until water temperatures start hitting the 50-degree mark.

Your best bet is to keep the aerator running.

Chances are that you’re not quite ready to get the filtration system up and running in your pond, so your aerator will continue to circulate the water and saturate it with oxygen.

Even when the water warms up, your aerator’s added circulation is great for the pond and fish during the hot summer months. Plus, it helps stimulate filtration and beneficial bacteria. If you leave it running, you’ll see that the benefits outweigh the nominal amount it costs to run it.
