Now that my plants are gone, how do I protect my fish? | Decorative Ponds & Water Gardens Q & A

Q: Now that my plants are gone, how do I protect my fish?

Q: Now that my plants are gone, how do I protect my fish?

Vicky – Chatham, NH

A:  This time of year, aquatic plants are tough to find in backyard ponds. Cold temperatures and fewer hours of sunlight make all the lush greenery die off or go dormant for the winter — and that leaves your fish high and dry and without any protection from hungry predators, like raccoons, herons and passing coyotes.

The lack of lily pads, hyacinth leaves and other plant cover also means more sunlight will penetrate the water. All those rays can lead to algae blooms and poor water quality, which is not something your hibernating fish will appreciate.

So how do you protect your finned friends from hungry bad guys during the sparse winter months? Here’s what we recommend.

  1. Create fish habitats: Because fish will naturally hide in crevices between rocks and other sunken debris, replicate that environment by creating fish habitats and caves. Prop up some slate slabs to make a fabricated lean-to. Build extra hiding places with clever rock placement. Provide an ecosystem that will encourage them to do what’s natural.
  2. Install fish shelters: In the winter, fish will intuitively head to deeper water where it’s warmer and safe from claws, paws and beaks. But to add another layer of protection — particularly if your pond isn’t that deep — give them plenty of sheltering options. Install a Koi Kastle or two. Lay down some empty flower pots or short lengths of 4-inch PVC pipe. Give your finned pals plenty of options to hide, just in case predators stop by the pond.
  3. Crank on your aeration system: As your aeration system bubbles and infuses oxygen throughout the water, it creates water surface movement that can help camouflage your fish from overhead predators. The aerator will also keep the water churning, and create a hole in the ice for gas exchange. If it’s not running already, now’s the time to crank it on!

Until your plants start growing again, keep your fish safe and sound with these simple steps – and do it before the frigid temperatures really kick in.

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.

I’m loosing water even after turning off my waterfall, but I don’t see any evidence of a leak. Help! | Decorative Ponds & Water Gardens Q & A

Q: I’m loosing water even after turning off my waterfall, but I don’t see any evidence of a leak. Help!

Paul – Cherry Hill, NJ

A:  Missing water, eh? Well, there are several logical explanations for your “Case of the Disappearing Water” pond mystery. This time of year, a water feature will lose water for all sorts of reasons, including:

  • Humidity Levels: When the humidity levels are low and the air contains little moisture, the dry atmosphere will act like a sponge, increasing evaporation rates and absorbing the water from your pond.
  • Windy Weather: Breezes are common during autumn, and those winds can also escalate evaporation in your pond. A 5-mile-per-hour wind at your pond’s surface, for example, results in roughly three times the evaporation rate on a still day!
  • Leaky Liner: Leaks can be tricky. Your pond and waterfall may appear to be leak-free, but a slow, inconspicuous one could have formed in your plumbing, or one could have happened after some rocks shifted. Take a look at this article for tips on finding and fixing a leak.
  • Freezing and Thawing: Though freezing temperatures are rare this time of year, ice formation and expansion can happen—and it can cause your pond’s volume to look like it’s changing. As the water freezes, it’ll take up more space than liquid water and appear to be disappearing when it’s really not.

So what can you do about the disappearing water?

First of all, if you haven’t already, shut down fountains, spitters, waterfalls and other extra water features. This will reduce splashing that can lead to water loss. Remember: The more surface area, the more loss from evaporation, so reduce surface area by keeping the surface water still.

Next, keep the pond filled by topping your water levels off with a garden hose—particularly on dry, windy days when evaporation is at its peak. Winter weather will eventually bring icy temperatures and frozen hoses, so keep a thermostatically controlled Thermo-Hose™ handy to ensure the water inside the hose stays liquid. The built-in heating elements turn on when the temperatures dip below freezing, preventing ice from forming. If you are refilling with tap water don’t forget to add Water Conditioner.

Finally, for your pond’s and your fishes’ health, install an aeration system to keep the water circulated below the pond’s surface. An easy-to-install system like the PondAir™ & Thermo-Pond De-Icer Combo will gently aerate and pump oxygen into the water while keeping a hole open in the ice to allow for gas exchange.

Water loss is common, but with these tricks you can minimize the evaporation while maintaining your pond over the fall and winter.

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!

My water garden doesn’t ice over, but the water gets cold. Can I still use barley extract during the winter? | Decorative Ponds & Water Gardens Q & A

Q: My water garden doesn’t ice over, but the water gets cold. Can I still use barley extract during the winter?

Q: My water garden doesn’t ice over, but the water gets cold. Can I still use barley extract during the winter?

Mary – Marietta, GA

A:  Barley straw is effective stuff. It’s an all-natural, chemical-free option for keeping pond water clear. And the best part? The temperature-tolerant natural pond treatment can be used year-round—even if your pond’s water gets cold.

Ever wonder how this seemingly innocuous bale of dried barley straw works? Read on to learn more.

It’s Science!

Though researchers have yet to precisely pinpoint how barley straw works, it’s generally believed that as a barley straw bale breaks down in water, it produces and releases many chemical compounds—and one of them may promote clearer pond water.

It has not been found to harm fish, water fowl or pond inhabitants in any way and, in fact, some studies suggest the straw benefits fish health.

Pond Particulars

When using barley straw in a water garden or backyard pond, forward-thinking hobbyists originally placed bales of it in their waterfall filter boxes, skimmers or waterfall areas where it would decompose. Things have sure changed! Those unwieldy bales have since been replaced by compressed, easy-to-use pellets and barley extract, which is basically the good stuff in a bottle.

If you’re thinking about using barley straw in your water garden, you have more options than ever. Check out these four popular methods:

  • Barley Straw Bales: Typically available loose in a mesh bag, small bales of barley straw can be placed in the pond several months before pond clarity issues are expected to occur (around March or April, depending on your climate) as the straw must start to decompose before it releases it’s special compunds. In a 1,000-gallon pond, 1 pounds of barley straw is needed, but it should be replaced every four to six months. Keep the straw well-aerated, floating it near your waterfall or stream or in shallow water. Don’t leave it in your pond beyond its prime time, however, because it can eventually become a nutrient source for algae.
  • Barley Pellets: Compressed into a compact form, Barley Straw Pellets also contain all the beneficial substances found in barley straw without the unsightly look of bales, pillows or pads. The pellets may also buffer pH and control alkalinity in your pond. A 6-pound bag will treat an 800-gallon pond for up to six months; a 12-pound bag will treat a 1,600-gallon pond for up to six months.
  • Barley Extract: Offering the benefits of barley straw without the mess or unsightly bale floating in your pond, Barley Straw Extract contains those beneficial substances in liquid form. Because you don’t have to wait for the barley straw to decompose, it goes to work on contact. An 8-ounce container treats up to 4,000 gallons for three months; a 16-ounce bottle treats up to 8,000 gallons for three months.
  • Seasonal Defense®: Seasonal Defense® gives you the power of activated barley straw with an additional punch of natural bacteria in one simple treatment. Used when water temperatures drop below 50°F, Seasonal Defense® helps break down muck caused by leaves, scum and sediment.

No matter what form you choose, barley straw extract is a good tool to keep in your water garden tool chest. It’s an effective solution you’ll use all year round.

Running a pond heater is expensive. Do I have any other options? | Decorative Ponds & Water Gardens Q & A

Q: Running a pond heater is expensive. Do I have any other options?

Q: Running a pond heater is expensive. Do I have any other options?

Vicki – Pawtucket, RI

A:  Yes, those pond heaters are expensive to run! But guess what? You don’t need one in the first place!

Heaters are more frequently used in aquariums, particularly those that house warm-water fish like tetras, danios or angelfish.

In your pond, the fish will overwinter just fine without a heater—even if temperatures drop below freezing. Pond fishes like koi and goldfish naturally go into wintertime hibernation when temperatures fall. They’ll stop eating, their metabolisms will slow way down and they’ll snooze through the winter without worrying about how warm their water is.

However, if you live in areas that experience freezing temperatures that cause your pond to ice over, you do need to worry about keeping a hole in the ice. The hole allows toxic gases like ammonia to escape while allowing oxygen in, and your fish will need that fresh O2.

So how do you create that hole? Not with a pond heater! Check out these much cheaper alternatives:

  • De-Icer: A de-icer floats on the water surface and melts a hole in the ice. Unlike a heater that actually warms the entire pond, a 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™ (for smaller ponds) or KoiAir™ (for larger ponds) circulates the water below the ice sheet. In areas with mild winters, that subsurface water movement will keep a hole in the ice—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 de-icer and PondAir™ Aeration Kit, providing your water feature the one-two punch it needs to stay well-vented throughout the winter. Watch the video below for benefits and installation.

If you live in an area with temperatures that hover around the freezing mark, consider picking up a Thermo Cube®. It’s a thermostatically controlled outlet that turns on when air temperatures drop below 35°F and turns off when air temps rise above 45°F.

So put that pond heater on Craigslist and invest in a de-icer, aerator and thermostatically controlled outlet. It’ll save you money in the long run!
