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!

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?

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.
