If I chose to bring my fish indoors for the winter what should I do? – Decorative Ponds & Water Gardens Q & A

When should I remove the fountain from my pond?

If I chose to bring my fish indoors for the winter what should I do?
Lisa – Livonia, MI

While we don’t really like to think about it, there are places in the U.S. that get cold enough to freeze decorative water gardens solid. As your fish do not appreciate being turned into popsicles you will probably want to bring them indoors for the winter. Since the majority of you don’t have a beautiful indoor pond just waiting to house our fish in the colder months how do you go about creating a safe environment for your fish to bunker down in?

Your first and foremost priority is to select a location that is climate controlled, safe from disturbances and large enough to facilitate a holding tank. Your basement or heated garage are a couple places you can consider. The container you choose to hold your fish should be made of a fish safe material and should be cleaned thoroughly before use. The size of this container will depend on the size and number of fish you need to relocate. Unless they are Sardines your fish will not do well when packed tightly into a tiny container. Purchasing a small pre-formed pond liner is a great idea for someone who has large Koi or an ample amount of fish that need a winter home. You will also want to purchase some Pond Netting to keep your fish from jumping out of their winter apartment and onto your garage floor.

The new container can be filled with water from your water garden or you can start from scratch and fill it with tap water. If you decide to fill from the tap you will want to add a Water Conditioner to neutralize any chloramines and remove other potentially harmful elements from the water. In addition to pond conditioner you will want to allow a few weeks for the water in the container to cycle and balance. Aeration and filtration will play a major role in the well being of your fish once they are relocated. If you currently use an external Pressurized Filter your water garden this can be used for your inside application as you will have to bring it in for the winter regardless. You will also need a small pump to circulate the water in this container as well which you may also be able to borrow from your outdoor water garden. If you have neither a pump nor pressurized filter on hand you can purchase an All-In-One system to do the job. If you have to use a new filter or you decided to fill the container with tap water seed your filtration pads with PL Gel to ensure an adequate presence of beneficial bacteria and reduce the waters cycle time.

When the time comes, collect your fish using a Fist Net and transfer them to their new home using the same acclimation process you would undergo with new fish. If you are unsure of how to acclimate your fish click over to our Blog that explains the process in greater detail. Do not feel the need to rush through the transporting process as your fish are safe and comfortable in their water garden for the time being. Take your time to make sure your fish are moving into a safe and comfortable environment so you and your fish can enjoy some indoor ponding this winter.

Should I vacuum my pond? – Decorative Ponds & Water Gardens Q & A

Should I vacuum my pond?

Should I vacuum my pond? Heather – Landfall, MN

Regular pond maintenance throughout the ponding season ensures clean clear water. An extremely lucky few may find themselves in a scenario where their pond is perfectly balanced with no debris blowing into the pond and no layer of muck developing at the bottom of their water feature. Then there are the rest of us who deal with slimy gravel or decomposing leaves and fish waste yucking up our ponds. Pond vacuums are a handy tool to make pond cleaning manageable and easy by physically removing hard to reach muck and debris from within the pond without bending or scrubbing.

While there are a number of vacuums available for purchase, the best type for you will depend on the size and type of pond you are trying to clean and what you are trying to clean out of it. If you have a small pre-formed pond or a fountain that you need to remove debris from then a small water-driven vacuum may be the perfect fit. An example of this type of vacuum is the Laguna Pond Vacuum Kit which consists of a water-driven vacuum head and hydro brush attachment. Water-driven pond vacuums attach to your garden hose and use the water flow to create suction. A mesh net placed behind the vacuum is used to catch debris.

If you are looking to clean out fine silt-like debris or have a large water feature you would be better suited with a motor driven Pond-O-Vac IV or Pond-O-Matic XL. These pond vacuums plug into a standard 110 volt power outlet and use a motor to create suction. These types of pond vacuums carry water and debris through the vacuum hose and into a reservoir which can then be discharged outside of the pond through a drain hose. Both vacuums come with extension handles and a full arsenal of attachments to clean hard to reach areas of the pond. The Pond-O-Vac IV’s dual chamber system, rugged wheels, and powerful motor make it the ideal vacuum for those of you with large water features as it is easier to maneuver than the Pond-O-Matic. The dual collection chambers cut your cleaning time as the vacuum never has to shut off to discharge. Once one collection chamber fills the vacuum switches to the empty chamber and continues to work, emptying the filled chamber in the process. If you have gravel or stones at the bottom of your water feature using one of the vacuums smaller attachments will keep you from sucking up stones along with your muck. If the bottom of your pond consists of dirt or fine pea gravel you will find yourself spending more time cleaning dirt and gravel from your pond than muck and debris. You may want to consider implementing a different substrate material or just focus on using Muck Defense bacteria to help digest bottom dwelling debris.

Better Pack a Cold Lunch

As the temperatures begin to cool down at the end of the year you will notice a change in the behavior of your Koi and Goldfish. Your fish will start to slow down and become less active as the water gets colder as they prepare for a winter of dormancy. You will still want to feed your fish in these cooler fall temperatures. A change in diet will help maintain happy and healthy fish and prevent potential fish kills going into the winter.

A decrease in activity means that your fish are slowing down and this is not just in regards to the energy level but to their bodily functions as well. Your fish will still be hungry and want to eat but because their digestive system slows down they will require less food and will take longer to digest what you’re feeding them. This can be problematic if you continue feeding your fish heavy high-protein foods in the cooler seasons. Excess food that has not been digested can begin to rot inside the fish before they can excrete it as waste causing illness and even death.

Fish food containing wheat germ like Pond Logic® Spring & Fall Fish Food are designed for colder weather feeding. Your fish have an easier time digesting these types of food at low temperatures which will keep them full and happy without putting them at risk. Knowing what types of food to use in colder temperatures is important but when do you make the switch? When your water temperatures fall between 40-50 degrees Fahrenheit you will want to start feeding with your Spring & Fall food. The best way to monitor the temperature of your pond is to use a Floating Thermometer and watch your fish for decreased activity. If they tend to just stay at the bottom of the pond and are not interested in eating before the water temps dip below 40 degrees then you can stop feeding early. Food that is left to sink to the bottom of the pond will turn into muck and aid in algae blooms come early Spring. If your fish are still active and eating you can feed them Spring & Fall food until the water temps fall below 40 degrees. During the winter your fish will just relax at the bottom of the pond in a state of dormancy until the water temperatures warm back up in the Spring.

Can I enjoy my plants indoors for the cooler months? – Decorative Ponds & Water Gardens Q & A

Can I enjoy my plants indoors for the cooler months? Josh – Speed, KS

With winter on the way, you are probably starting to wonder how to go about protecting your plants through the colder months. Just as each plant is unique in looks and application, different types of plants require different means of protection to survive winter. You will want to properly identify which types of plants are present in your pond and proceed accordingly. If you are willing to go the extra mile and care for your plants indoors you will be able to enjoy them all season long and dodge the expense of re-buying plants to garnish your pond next Spring.

Plants are typically categorized by hardiness which gauges their survivability in specific temperature ranges. Some plants, like Bog Bean are rated from zones 3 to 10 which means they can withstand very cold temperatures but can also thrive in warm weather. Tropical plants like the Antares Lily are hardy only in zones 10 and 11. For help, see our Plant Hardiness Zone Map which breaks down temperature lows in each zone. With this being said you will now understand that some plants may need to be stored earlier and longer than others and may require a little more attention depending on their warmth and light requirements and if you maintaining the entire plant or only storing tubers.

Hardy Lilies and Lotus can be trimmed back to about an inch` away from the top of the planter as they brown. To over winter these plants you simply sink the baskets to a depth in your pond that will not freeze solid, normally at least 12” in water depth. As the temperatures warm back up you can move the basket closer to the surface and let nature take its course. If your lilies aren’t potted, they are more than likely planted into lily pockets that are already 12-18” in depth and simply trimming them back will suffice. Any tropical plant, however, will have to come inside for the winter. These plants can be maintained if placed in a warm and sunny area or under a full spectrum light and the root of the plant is kept submerged.

Submerged Plants that are hardy in colder climates can just be sunk to deeper regions of your pond that will not freeze solid in the winter. If they require warmer temperatures you can bring them in and store them in an aquarium with full spectrum lighting.

Floating Plants like Water Hyacinths and Water Lettuce are sensitive to colder weather and are a little more difficult to over winter. If you choose to bring them in for the winter, they require a warm sunny location or under full spectrum lighting. You will also want to add some liquid fertilizer like Microbe-Lift Bloom & Grow to keep them healthy.

How can I keep leaves out of my pond? – Decorative Ponds & Water Gardens Q & A

This Tent’s Not for Camping

You may not want to admit it yet, but the summer season is coming to a close. While we love the mild weather and the changing colors of the trees, us water garden owners have to turn our attention to the falling leaves. No worries however, we have one simple tool that you can use to avoid having to deal with leaves falling into your water garden.

We are of course talking about pond netting. If you dealt with Herons in the summer you may already have a pond net on hand. While they are great for keeping unwanted predators out of your pond they are more commonly used for keeping leaves and other blowing debris from falling in. There are two basic styles of pond netting you can purchase. The most simplistic version of this being a pre cut piece of mesh netting. This netting is available in an Economy Grade which is ideal for single season use or a Heavy Duty version. You can pull this mesh tight across the surface of your pond and secure it using stakes or rocks. This application works well for water gardens that may receive minimal amounts of debris. If you are in a heavily wooded area or are prone to massive amounts of debris you will be better off utilizing a Pond Protector Net Kit that implements a domed design to better protect your pond. The netting included with the kit extends beyond the tent-style frame allowing you to pull netting along the contours of your pond so there are no gaps left open for debris to enter.

Keeping leaves out of your pond in the fall will help keep the pond clean and manageable going into the colder seasons and will ensure a faster, easier cleanout and start up next season. Leaves left in the pond to decompose tend to create “tea-colored” water due to the tannins they release in the decomposition process. You can fill Media Bags with Activated Carbon and place them in your filter boxes to help clear the water if this happens to you. Also continue to use Nature’s Defense and Muck Defense to manage the muck left behind by decomposing leaves and fish waste. As water temperatures fall below 50 degrees Fahrenheit you can switch from Nature’s Defense and Muck Defense to Seasonal Defense. Seasonal Defense is a cool water natural bacteria that will continue the decomposition process throughout the fall and winter.

I want to leave my pond running through the winter. Can I do so without damaging the equipment? – Water Garden & Features Q & A

Water Garden & Features Q & A

Q: I want to leave my waterfall running through the winter. Can I do so without damaging the equipment? – Karen in New York

UPDATED: A: A majority of water garden owners will shut down their water gardens entirely during the Winter, but there are a few that don’t.

It’s really beautiful to see a waterfall with pieces of ice around it. You’ll actually begin to see sections where the water flows underneath the ice throughout the stream. It really is a beautiful scene.

Here are a few factors to be aware of when running the waterfall and stream throughout the Winter:

Pump Size (Gallons Per Hour): The amount of GPH or gallons per hour of a pump must be greater than 2,000 as the water is coming down the waterfall and stream. If this flow is not obtained, then there is a greater possibility the water could freeze, causing ice dams in the stream and pushing the water over and out the side of the stream. If this happened, your water garden would be drained in no time.

Pump Location: If your pump is located directly in the pond and not in a skimmer, make sure that it is located in at least 24″ of water. Don’t place the pump on the very bottom of the pond. Your fish go to the bottom of the pond to hibernate during the winter.

Long Streams Beware: Even if you have 2,000 GPH of water coming down the stream, if the stream is quite long, longer than 10′ or 15′, then I wouldn’t suggest to run the system throughout the winter. In long streams, there is more opportunity for ice dams to form and thus draining your water garden. If your stream is longer than 10′ to 15′ and you still want to try and run your system I would advise you to use a little bit more flow than 2,000 GPH and to watch it regularly to make sure these ice dams are not created.

Pressurized Filters: If you use a pressurized filter in your pond I would recommend NOT to run the water through it during the winter time. It is best to drain the pressurized filter to prevent any water from freezing and damaging the equipment.

Consider a back-up plan: If you live in a freezing climate and you keep your pond running, you run the risk of damaging your plumbing and filtration system if the water stops flowing. If your pond design allows the water to flow back into the pond in the event of a power outage, you can avoid the problem.

In freezing climates, certain water features, like spitters or decorative fountains, will need to be shut down until spring. Simply drain the water from the feature and remove the pump. Submerge the pump in a 5-gallon bucket filled with water (or per manufacturer’s recommendations), and store it in a place where the water will not freeze. If you don’t keep the pump submerged in water and it dries out, the seals inside the pump could crack, causing the pump not to work properly.

How do I “overwinter” or get my pond plants ready for the winter? – Water Garden & Features Q & A

Plants must not come into contact with ice or freezing temperatures.

Water Garden & Features Q & A

Q: How do I “overwinter” or get my pond plants ready for the winter?
- Maryann in Wisconsin

A: If you live in cooler climates – even those that don’t dip too far below freezing – it’s almost time to prepare your plants for winter. Each type of aquatic plant needs to be cared for in a different way, but the most important factor to remember is that the roots of your plants must not come into contact with ice or freezing temperatures. If they do, they simply won’t survive.

Keeping in mind regional variances, here’s how to keep your aquatic plants healthy, happy and ready to bloom again next spring:

    1. First, remove any dead leaves from the plants growing around your pond. Give bog plants, like irises and taro, a good inspection and clip off any unhealthy growth, spent leaves or blooms. You want your plants to go into winter as healthy as possible so they emerge strong and stout in the spring.
    2. Next, pull on your waders and tend to your hardy water lilies. Pull them out of your pond and trim them to about 3 inches above the root system. When you’re done, move the pots or baskets to 18 inches deep or lower, where they’ll be warm and safe from winter frost.
    3. If you have tropical and floating aquatic plants, like tropical lilies or lotus, it’s easiest to treat them as annuals: Remove them from your pond and mulch the soil and root balls. In most climates, they won’t survive the cold winter conditions. You can try to overwinter them in your shed or garage, but it can be difficult, as many of the tropical varieties require temperatures above 60 degrees Fahrenheit and strong light to survive.
    4. Treat floating aquatic plants, like water hyacinth and lettuce, as annuals, too. Fortunately, they’re relatively inexpensive to replace year after year.
    5. For hardy lotus, trim back the foliage after they have gone dormant and turned brown. Don’t trim them while the plant and leaves are still green, as it can cause it to be susceptible to diseases that creep in through the hollow stems. In cooler climates, move your plants to a cool, but frost-free area in your yard or the bottom of your pond, along with your water lilies.

Depending on the size of your pond and the number of plants you have, this winterizing chore shouldn’t take longer than an afternoon, but you’ll be rewarded in the spring with healthy growth that will once again beautify your outdoor living space!

Algae Growth During the Winter – Water Garden Q & A

Algae Growing in a Water Garden During Winter.

Q: I shut my water garden down for the winter, but I still see some algae growth. Can algae grow in cooler temperatures?

A: In some cases, a pond that stays clean and clear through the summer can blow up into an algal nightmare in the fall. Shutting down your watergarden ceases the flow-through characteristics of the pond. This reduces the amount of filtration that occurs both mechanically (i.e. skimmers) and biologically (i.e. filterfalls). Since there is less flow, it is a good idea to bump up the amount of bacteria in the pond by adding Seasonal Defense Bacteria with Barley. These bacteria operate in cooler conditions and will greatly reduce the amount of nutrients in the water, and also contains barley straw to naturally help with the algae. Using Oxy-Lift Defense to scrub down your rocks will also help to remove any debris build up.

Do I Have to Take My Koi Out of My Water Garden for Winter? – Water Garden Q & A

Picture of a Water Garden in the Winter with a Bubbler Aeration System.



Q: Do I have to take my koi and goldfish out of my water garden for the winter? – Barbara of Massachusetts

A: No you don’t actually. They are many water garden owners who leave their koi and goldfish in their water garden throughout the winter season with no issues whatsoever. There are really only two things that you need to do to make sure your water garden is fit to allow fish to winter over:

Does your water garden have a depth of at least 18″?:
This is very important. There are places in the US alone where water freezing depths can easily be around 18″ to 24″. I suggest a minimum of 18″ of depth to be safe, but I am more inclined to recommend 24″ just to be double safe. We want to make sure our fish friends don’t become icicles. In either instance, it’s also extremely important to make sure we keep a hole open in the ice during these cold times, which leads me to the second thing.

Keeping an open hole in the ice during the winter:
During the winter, when the ice forms a solid layer across on the surface of your water garden, there are toxic gases, caused by decaying vegetation or organics, that can build up underneath the ice. This build up can become so toxic underneath the ice that it can kill all of the fish in the water garden. The best thing to do in this situation is to keep a hole open in the ice to allow for these gases to escape. This is actually very easy to accomplish. Using a pond heater/de-icer, such as a Pond Saucer or ThermoPond, is a great way to keep a hole open in the ice. Another way to keep a hole open in the ice would be to use a small bubbler aerator. These will not only keep a hole open in the ice, but will also add oxygen as well! Bubbler aerators can be used all year to keep oxygen levels high.

Should I Drain My Water Garden Completely for the Winter? – Water Garden Q & A

Picture of a Pump in a Skimmer.



Q: If I take my fish inside, can I drain my water garden completely for the winter? Someone told me that you shouldn’t do that. Why? – Toni of New York

A: If you plan to shut-down your water garden, you should drain the water down below the skimmer opening and yes you would leave the water in the pond. The reason for this is to help prevent some shifting within the water garden. The ground will shift throughout the winter and if you were to drain the water garden entirely, it could cause certain sections of the water garden to cave in. Having the water in there will keep everything at bay by applying pressure to all sides.

Also, when lowering the water level below the skimmer, make sure to drain the skimmer out entirely. Allowing the water in the skimmer to freeze could cause damage to the skimmer itself. The same goes for the waterfall filter. As for what to do with the pump, here is a link to a previous post.
