What do you really mean when you say fish are “dormant” for the winter? Do they sleep? | Decorative Ponds & Water Gardens Q & A

Q: What do you really mean when you say fish are “dormant” for the winter? Do they sleep?

Q: What do you really mean when you say fish are “dormant” for the winter? Do they sleep?

Diane – Wells, ME

A:  When the days shorten and temperatures drop, koi and other pond fish enter into what’s called torpor, or a period of decreased physiological activity that allows them to save energy. They don’t sleep the winter away, but they do essentially hibernate—their metabolism slows, they require less food, their activity level drops and their body temperatures reduce.

How do they know they need to hibernate, and what can hobbyists do to make their finned friends’ winter torpor restful? Read on to learn more.

Mother Nature’s in Charge
Fish don’t use calendars to decide when to take their winter snooze. Instead, they follow Mother Nature’s lead. Because fish are cold-blooded, their metabolism reacts to the external environment. When the water temperature falls, so does their activity level: Their appetite dwindles, they digest food more slowly, and they expend less energy. In the spring when temperatures warm back up, the fish will naturally come out of their torpor. They’ll start to seek out food as their metabolism increases, and they’ll become active once again.

Suspended Animation
You’ll know when your fish go dormant. They won’t lie down on the pond’s bottom or curl up in their cozy Koi Kastle, but they will float upright, tuck in their fins and remain suspended in the water. As the fish hover there, you may still see some super slow movement, and they may also wind up facing in the same direction as if they were heading somewhere at less than a snail’s speed.

Sweet Dreams, Koi!
Here are four ways to give your koi a peaceful winter rest:

  1. Set up an aeration system to keep the water pumped full of oxygen. Even though they’re hibernating, your fish will still need some fresh O2.
  2. Install a de-icer to keep a hole open in the ice and allow for gas exchange. If the pond freezes over, use warm water to reopen a hole; do not bang on the ice to crack it, as doing so can stress your fish.
  3. Keep as much debris out of the pond as possible to prevent muck buildup over the winter.
  4. Let the fish be. Don’t try to get them to move or swim or wake up from their slumber. Keep an eye on them, but leave them alone until they wake up on their own.

My UV bulb was still working when I pulled it out for the winter. Do I still need to replace it? | Decorative Ponds & Water Gardens Q & A

Q: My UV bulb was still working when I pulled it out for the winter. Do I still need to replace it?

Q: My UV bulb was still working when I pulled it out for the winter. Do I still need to replace it?

Richard – Avon, IN

A:  A UV bulb is one of your best weapons in the battle against discolored water. When those ultra-fine particles are exposed to the bulb’s ultraviolet rays the tiny particles clump together, and those clumps are then removed by your mechanical filtration system.

What’s left behind is clean, clear water – as long as the bulb is working efficiently.

For your UV clarifier to work its best, it will need a new ultraviolet bulb every year. Even though the bulb still illuminates and appears to be working, its effectiveness decreases over time. Your best bet is to replace it when you do your annual spring cleanout, and plan to do so again year after year.

Spring Cleaning

In addition to switching out the bulb, take some time to check the quartz sleeve or glass tube that’s housing the bulb. Does it need a good cleaning? Debris can build up on the glass, preventing those powerful UV rays from penetrating the water as it passes through the filter. Use as soft cloth and a descaler (if needed) to scrub off the buildup.

Filter Check

While you’re at it, check your biological filter media and mechanical filter components, like the skimmer, pump sock and prefilters. Do they need to be cleaned or replaced? Even though your ultraviolet clarifier is tackling most of the discolored water, your filtration system is still responsible for removing the debris. Make sure they’re in good working order before the algae blooms in the spring.

Maintain a Balanced Pond

UV clarifiers do a great job at clearing water, but an even better solution is to maintain a balanced pond the first place. Reduce excessive nutrients by reducing the number of fish in your pond, minimizing the amount of food you feed them and cleaning up the waste they produce, as well as regularly removing the built-up detritus.

When should I start using the Seasonal Defense in my DefensePAC? | Decorative Ponds & Water Gardens Q & A

Q: When should I start using the Seasonal Defense in my DefensePAC?

Q: When should I start using the Seasonal Defense in my DefensePAC?

Chuck – Essex, MD

A:  Seasonal Defense®, contains aerobic bacteria that’s specially designed for cooler water. In the spring, it replenishes bacteria lost over the winter, jump starts the growth of the waste-gobbling microorganisms and breaks down accumulated waste. It’s a great way to kick off pond season!

Add It At 40 Degrees

Plan to start treating with Seasonal Defense® once your pond is up and running and the water temperature is greater than 40° Fahrenheit. You can expect to use it for about one month, or until the water hits 50°F. Once the thermostat tops 50°F, switch to Nature’s Defense®.

Distribute Evenly

Don’t just pile the Seasonal Defense® packets in one place in your pond. Put a packet in each corner to ensure even spread of the beneficial bacteria and breakdown of accumulated muck. Add some to the filter to concentrate and accelerate new bacteria growth on the filter media. Distribute them evenly—but, of course, follow the package recommendations for dosage rates.

Help the Bacteria Work

Don’t forget to aerate the pond and give it an old-fashioned cleaning to make those bacteria’s jobs easier. Along with running your pond’s pump and filtration system, keep your aeration system going to help move the water, add oxygen and disperse the bacteria throughout the pond.

And before you add the packets, clean out any large debris from the pond. Branches, dead foliage, fallen leaves and any other easy-to-remove organic materials that wound up in the water over the fall and winter should be removed so that the bacteria can better spend their time breaking down fine debris and muck.

We’ve been keeping our fish indoors for the winter and have filtration. Do we need to use any chemicals? | Decorative Ponds & Water Gardens Q & A

Q: We've been keeping our fish indoors for the winter and have filtration. Do we need to use any chemicals?

Q: We’ve been keeping our fish indoors for the winter and have filtration. Do we need to use any chemicals?

Shiela – Norton, VA

A:  No doubt your finned friends are enjoying the cozy indoors during the chilly winter season. With your tank’s filtration system turned on, you’re mechanically cleaning the fishes’ aquatic abode – which is a great first step – but there are a few more things you can do to make their stay inside a pleasant one. Here’s what we recommend.

No Chemicals Necessary

Unless your holding tank receives a lot of sunlight, you won’t need chemical treatments, like algaecides or water clarifiers. They’re not necessary, particularly if you use beneficial bacteria, stress reducer and an aeration system.

Boost Your Bacteria

Natural beneficial bacteria, like those found in The Pond Guy® Liquid Clear™, will keep your tank water clean (and give your mechanical filtration system a break!), so pour some into the tank. The tiny microbes activate as soon as they hit the water, multiplying every 20 to 40 minutes and digesting dead organics in the water. The result: crystal clear water and happy fish.

Condition the Water

A stress reducer, like The Pond Guy® Stress Reducer Plus, will help your fish enjoy their indoor stay, too. The water conditioner fortifies your fish’s slime coat, which is the natural slime secretion that’s lost when its stressed. It also removes heavy metals, chlorine and chloramines from tap water, making it safe for underwater living.

Aerate and Circulate

In addition to beneficial bacteria and stress reducer, you should also drop in some air stones into the tank and connect them to your aeration system. Because your fish are living in a smaller space, they’ll need even more oxygen than they did in your pond. Our PondAir™ Aeration Kits will infuse the water with plenty of fresh O2 for your fish until spring arrives again!

What items need to come out of my pond before winter? | Decorative Ponds & Water Gardens Q & A

Q: What items need to come out of my pond before winter?

Charles – Billings, MT

A:  You probably spent a pretty penny on your pond equipment, and so there’s no doubt you want to make that gear last as many seasons as possible. Certain components will survive longer if you remove them from your pond during the winter, including:

    • All-In-One Filtration Units: Submersible mechanical, biological and ultraviolet filtration systems such as the ClearSolution™ G2 should be pulled from your water feature, cleaned and stowed away for the winter in a place that will not freeze.
    • Pressurized Filters: As with the All-In-One Filtration Units, plan to remove pressurized filters such as the AllClear™ G2 and put it up for the cold-weather season. Doing so will prolong the life of your unit’s temperature-sensitive parts.
    • Pumps: Whether your pump feeds a waterfall, fountain or some other decorative item in your pond, it will need to be removed and stored in water in a spot that won’t freeze, like a heated garage or basement.
  • UV Clarifiers: If your ultraviolet clarifier is separate from your mechanical and biological filtration system, be sure to remove it from your water feature and store it until spring, when you should plan to replace the bulb.
  • Ion Clarifiers: Algae won’t likely be growing out of control in the winter, so you can disconnect your ion clarifier and keep it stashed until the warm weather arrives.

Once all of your gear is removed and stored away, blow out the water lines with your air compressor and cap the ends until spring. You wouldn’t want that water to freeze and crack your pipes!

Add Winter Gear

While you’re doing some winterizing chores, now is the perfect time to add an aerator to your pond to keep the water oxygenated for your finned pals during the winter months.

Airmax® PondAir™ Aeration Kit is designed for water gardens up to 2,000 gallons. It’s powered by an energy-efficient diaphragm compressor and includes an airflow control valve, air stones and flexible black vinyl air tubing.

The Pond Guy® Water Garden Aeration Kit is designed to aerate medium sized water gardens and koi ponds up to 4,000 gallons. It’s powered by an energy-efficient aeration pump and includes a diffuser plate for maximum oxygen uptake and a weighted airline.

Completing these simple tasks will prolong the life of your pond gear and ensure your fish and other pond critters stay happy and healthy all winter long.

I’m shutting down my waterfall for the winter and installing an aeration system. Do you have any tips on running aeration? | Decorative Ponds & Water Gardens Q & A

Q: I’m shutting down my waterfall for the winter and installing an aeration system. Do you have any tips on running aeration?

Q: I’m shutting down my waterfall for the winter and installing an aeration system. Do you have any tips on running aeration?

David – Greenfield, IN

A:  Shutting down the waterfall for the winter makes a lot of sense for water garden hobbyists. Not only will it save on operating costs, but it will also prolong the life of your equipment, prevent ice dams from forming and potentially draining your pond, and save on a lot of hassle and worry.

You may be wondering why aerate? With the waterfall off, the pond will need another source of oxygen – and that’s where an aeration system comes into play. It pumps O2 into the water and maintains a gas exchange hole in the ice, ensuring any finned friends are safe and healthy through the cold season.

We’ve got some expert tips on aeration for you. Here’s what we recommend for making the most of your system.

  • Size It Right: Install an aeration system that’s large enough to properly ventilate your pond volume. An “a little is better than nothing” approach might not be enough to keep your fish safe. If your pond is less than 4,000 gallons, consider The Pond Guy Water Garden Aeration Kit. If it’s between 4,000 and 16,000 gallons, try the KoiAir Aeration Kit.
  • Pair with a De-icer: Though the water movement created by aeration can prevent most surface ice formation, add a de-icer just in case nighttime temperatures turn frigid. The PondAir & Thermo-Pond Combo – a combination kit containing an aerator and de-icer – is perfect for this. On particularly windy nights, you might see ice form even with a de-icer, but don’t worry. The aeration system is still adding oxygen to the pond, and the combination of the two will eventually reopen the hole.
  • Position in Shallows: Rather than place your diffusers in the deepest areas of your pond where your fish hang out in the winter, put them in the shallows or near the surface. Doing so will provide more water movement and better keep a hole in the ice.
  • Watch the Ice: If ice does form, don’t panic! Keep an eye on the ice. If a ventilation hole doesn’t reopen on its own within a few days, pour a bucket of hot water on the ice to help melt it open. Don’t – we repeat – don’t pound on the ice to break it apart. Your fish won’t like it. In fact, the sound waves will stress your fish, compromise their immune systems and could kill them.
  • Maintain for Best Results: Mechanical pieces and parts need to be maintained, and so if you’ve been using your aeration system for the summer or it has been dormant since last winter, it’ll need some attention. Check to make sure the airstones/diffusers are working properly, and install a maintenance kit to ensure it’s working to its full potential.

I don’t have a pond, so I have no fish or filter to worry about. Can I still run my water feature? | Decorative Ponds & Water Gardens Q & A

Q: I don’t have a pond, so I have no fish or filter to worry about. Can I still run my water feature?

Julie – Castleton, NY

A: Though we generally recommend folks shut down their pondless features in the winter, you can absolutely run it year-round—as long as you’re prepared to add a few winter chores to your to-do list.

Keep It Running
Because they don’t have filtration systems to fuss with or fish to care for, pondless and other small features really don’t require much winter care. Periodically, however, inspect it and check for the following:

  • Flowing Water: To prevent water from freezing in the feature’s plumbing during cold temperatures, keep water running at all times. The movement will minimize ice buildup.
  • No Ice Dams: Keep an eye on the ice formations around your feature. Make sure ice is not redirecting water out of the water feature. If so, melt it with warm water.
  • Refill as Needed: You’ll need to top off the water level through the cold season, so keep a water supply available to refill your feature as needed. A hose-warming device like our Thermo-Hose™ will keep your water supply flowing for feature refills.

Shut It Down
If you don’t want to mess with these chores, shut your water feature down for the season and store the pieces and parts until next spring. Here’s a quick three-step checklist to follow:

  • Scrub Down: First, give your feature a thorough cleaning. Use Oxy-Lift™ to help break debris from the rocks and waterfall, gently scrub as needed and rinse well.
  • Remove Pump: Next, empty out water basins and remove your pump for winter storage. Drain the tubing and store the pump in a bucket of water to keep the seals moist so they don’t dry out and crack.
  • Store Décor: Finally, disconnect and store any fragile water feature parts, like spitters or decorative vases in your garage or basement. Take temperature-sensitive plants inside for the winter, too.

Yes, sitting beside a gurgling waterfall on a frosty winter’s eve is a splendid way to relax after a long day (especially if you have a hot cup of tea and a patio heater cranked on!). But giving your feature a break for the winter while you stay warm and dry is a nice idea, too. Whatever route you choose, enjoy!
