Isn’t the waterfall enough aeration for my pond? | Decorative Ponds & Water Gardens Q & A

Q: Isn’t the waterfall enough aeration for my pond?

Q: Isn’t the waterfall enough aeration for my pond?

Staci – Bethel, VT

A: As your waterfall gurgles and churns gallons of water, it would certainly appear that your pond is getting plenty of aeration. All that action does, in fact, help with gas exchange and infuse oxygen into the water. But it isn’t always enough, especially if you run your waterfall pump for a short time during the day.

If a pond isn’t aerated enough, expect to see these telltale signs:

  • Algae Battles: Algae thrive in calm water that’s devoid of – and in need of – oxygen and beneficial bacteria. If you regularly fight algae blooms, that means your pond is out of balance and could use some additional oxygen and movement throughout the entire water column.
  • Oxygen-Starved Fish: Fish that need more oxygen will hang out beneath your waterfall, where oxygen supplies are the densest. They may also be coming to the water surface, gulping and gasping for breaths of air because there’s not enough in their environment.
  • Too Many Fish: The general rule for a fish population in a pond is to allow 1 inch of fish per square foot of surface area. If you have too many fish, or your existing population has outgrown their space, aeration is critical to their health and well being.
  • Stagnant Water, Mosquito Boom: Is the water stagnant in certain areas of your pond? Are you suffering through a mosquito boom in your backyard? These little pests prefer to lay their eggs and raise their young in still water – so you might have created a perfect mosquito habitat!
  • Muck Accumulation: Decomposing plant matter and fish waste build up when the water is still and your biological filtration system can’t keep up. That muck feeds the algae blooms, which create more muck.

Do any of these ring true? If so, your waterfall or stream is not providing enough aeration for your pond. An aeration system can help. The Airmax® PondAir™ Water Garden Aeration Kit is designed for smaller water gardens up to 2,000 gallons and The Pond Guy® Water Garden Aeration Kit is designed for water gardens and koi ponds that are up to 4,000 gallons. Both whisper-quiet systems can be run 24 hours a day, seven days a week, providing your finned pals and beneficial bacteria plenty of oxygen and water movement.

I’m starting my pond up for spring. Do I need to leave my aerator running? | Decorative Ponds & Water Gardens Q & A

Q: I’m starting my pond up for spring. Do I need to leave my aerator running?

Nikki – Glen Forney, PA

A:  As winter gives way to the sunny days of spring and summer, you should absolutely plan to leave your aerator running. That water-churning system that benefits your pond over the cold months will also benefit your pond during the summer—and then some.

Winter Bubbles
As most pond owners know, an aerator, like The Pond Guy® Water Garden Aeration Kit, used during the winter serves two purposes: to aid de-icers in creating and keeping a hole in the ice, and to circulate water to vent gases when filtration systems are shut down for the season. The circulation also encourages contact between the water and the environment, which will increase the dissolved oxygen level in your pond.

Summer Aeration
In the summer, aeration provides some extra benefits. Besides moving the water and boosting the oxygen level in the water molecules, aeration does these things:

  • Circulates the water in areas where filtration may not reach, preventing stagnation and low-oxygen pockets in your pond. Filtration systems only move the top of the water column, not the bottom. But an aerator works from the bottom up, circulating the water and increasing dissolved oxygen levels throughout the pond.
  • Keeps oxygen distributed throughout the water column much more efficiently than a water feature, like a waterfall, spitter or stream.
  • Provides bubbly camouflage in which fish can hide.
  • Stirs up debris on the pond bottom, allowing it to be filtered out or broken down by beneficial bacteria. If that debris is allowed to collect, muck will build up and release harmful gases as the organic materials decompose.
  • Helps beneficial bacteria thrive and flourish, thanks to the circulation and oxygen. Higher oxygen levels stimulate and increase the number of natural aerobic bacteria living in your pond. More bacteria means more efficient filtration.

As you’re prepping your pond for spring, jump start the season with DefensePAC® Pond Care Package. It contains Oxy-Lift™ Defense®, Nature’s Defense®, Clarity Defense®, Muck Defense® and Seasonal Defense® — everything you’ll need for spring cleaning, bacteria boosting and water clarifying.

Aeration definitely has its benefits, no matter what the season. If you want a balanced ecosystem with healthier fish and plants, keep your aerator running.

My pond froze over. How do I get it open again? | Decorative Ponds & Water Gardens Q & A

Q: My pond froze over. How do I get it open again?

Janet – Minneapolis, MN

A:  Brrrr. Jack Frost, Elsa and the rest of the cold-weather crew sure have been busy lately, haven’t they? Despite the use of a de-icer, aeration system and other ice-prevention tactics, long bouts of frigid temperatures and wind-whipped nights can cause ponds to freeze over. And that’s not good news for your fish.

So what can you do? When considering your hibernating finned pals, time is critical. Too long without an open area in the ice for gas exchange could mean dangerous conditions for your koi, goldfish and other pond fish.

Overnight, No Problem

If the pond has been frozen over since last night, your fish should be just fine. Cold, windy nights often cause extra layers of ice to form on the pond’s surface. If your de-icer and aeration are on and functioning properly, some of the ice should melt on its own. Meanwhile, your fish will have plenty of dissolved oxygen in the water to tide them over.

A Week or More, Get Busy

If it’s been a week or longer with no hole in the ice, it’s time to take some action. Without a hole, ammonia and other noxious gases are unable to escape into the atmosphere, and your fish will have no access to fresh oxygen. Here’s what to do when ice overtakes your pond.

  1. Melt It: First, melt a hole back open in the ice by pouring a bucket of hot water onto the frozen stuff near your de-icer or aerator’s airstones. Do not drill through the ice or bang on it with a hammer as this will stress your fish, which are probably already stressed out.
  2. Systems Check: Once a hole is open, check to be sure your de-icer and aeration systems are still running and functioning properly. If not, repair the damage or replace the unit altogether. The PondAir™ & Thermo-Pond Combo, which is an all-in-one aerator and de-icer, works to keep a vent open in ponds up to 2,000 gallons. See the video below for tips on installing the PondAir™ & Thermo-Pond De-Icer Combo.
  3. Reposition Airstones: Finally, if your airstones are positioned at the bottom of your pond, relocate them. Put them in a shallower area that’s closer to the water surface. This will create more movement – and that means a bigger hole.

Should frigid temperatures and a solid ice sheet persist, take a daily trip to your pond to check on the gas exchange hole. Your aerator and de-icer should do the trick, but be ready to melt through the ice if needed.

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.

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!

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.

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.

We’ve decided to shut down the pond this winter. Do we just need to take out the pump? | Decorative Ponds & Water Gardens Q & A

Q: We’ve decided to shut down the pond this winter. Do we just need to take out the pump?

Tina – DuBois, PA

A:  Oh, if it were only that easy. Even though you plan to shut down the pond for the season, you still need to complete some winterizing chores. Put on your Aqua Gloves and hip waders. Here is your step-by-step guide for closing down shop and storing your pond equipment for the winter.

Step 1: Remove Pond Netting

Do you have a leaf-collecting net covering your pond? Once the colorful foliage has stopped falling, remove the net, shake off the leaves and store it until next fall. If you leave it on the pond, heavy snowfall and ice could collect on it and weigh it down—possibly endangering your fish.

Step 2: Disconnect Filters and Pumps, Lower Water Level

Next, protect your pumps, filters and hardware from the freezing temperatures. Disconnect the plumbing and drain the water from the tubing to prevent them from freezing, expanding and cracking. If your filtration system has built-in ultraviolet filter or if you have a UV clarifier, disconnect it and take it indoors to prevent ice damage. Remove your pump and store it in a bucket of water to keep the seals moist so they don’t dry out and crack. And lower your water level below the opening of skimmers to protect it from expanding and cracking during freezing temperatures.

Step 3: Clean Filters and Media

Natural bacteria that have been thriving in your pond will become dormant and die through the winter, so you can remove your filter media and store it indoors for safe keeping. Be sure to wash the pads or BioBalls with a strong stream of water while they’re still wet; it’s much easier to clean UVs and media when they’re wet versus trying to scrub off dried debris in the spring.

Step 4: Trim Back Aquatic Plants and Remove Excess Debris

Do you have plants in your pond? Tropical varieties—like tropical lilies—must be removed and stored inside if you hope to keep them thriving until spring. Check out this blog post that details how to remove and store them. Hardy varieties can stay in the pond; take some time to trim away dead or dying foliage after the first frost. While you’re at it, pull out your ClearVac pond vacuum and suck up as much detritus as possible. The less rotting debris in the pond, the more available oxygen for fish.

Step 5: Install De-Icer and Aeration
Your fish will take a winter nap through the cold season, but they’ll still need oxygen to survive. If you live in an area that freezes, be sure to install a de-icer, aeration or both (as we feature in our PondAir & Thermo-Pond De-Icer Combo) to help maintain a hole in the ice. That will allow the toxic gases to vent and oxygen to enter while circulating the water.

Step 6: Switch to Wheatgerm Fish Food
If you haven’t already switched to wheatgerm fish food, do so now. Our Spring and Fall Fish Food is easier for your finned pals to digest—which is what they need when temperatures start to fall. As the water reaches 40 to 50 degrees F, slow down and stop feeding them for winter. Remember that with no filtration system running, any waste they produce won’t be sufficiently removed.

Step 7: Add Seasonal Defense
Finally, if temperatures still permit, continue to add natural bacteria designed for cooler temperatures, like Seasonal Defense. The little microbes will continue to break down organic waste that wasn’t easily cleaned from the pond.

As you prepare to shut your pond down for the winter, take time to check off these chores. It’ll make next year’s spring pond season one to look forward to!
