Q: My pond is 18 inches deep. Can I overwinter my fish in my water garden?
Jessica – Hope Valley, RI
A: Great news! Unless you live in an extremely frigid climate, your pond is at the minimum depth required for overwintering fish in a pond. Though 24 inches or deeper is better, 18 inches should give your finned friends enough room to ride out the cold temperatures—as long as you keep a hole open in the ice.
Freezing winter temperatures will create a solid layer of ice on your pond’s surface. Below the ice sheet, decaying vegetation and organic matter release harmful gases, like ammonia, which can build up and kill your fish. A hole in the ice will allow for gas exchange. The oxygen will enter the pond, the gases will escape, and your fish will stay happy and healthy while they’re hibernating.
To keep that hole open, here’s what you’ll need based on your zone:
- Occasional Below-Freezing Temps: For temperature zones that get the occasional below-freezing day or low nighttime temperatures, use an adjustable air stone aerator, like the Airmax® PondAir™ (up to 2,000 gallons) or Airmax® KoiAir™ (up to 16,000 gallons). One of these units will infuse your pond with oxygen while remaining quiet and cost-effective.
- Long Stretches of Freezing Temps: For temperature zones that see long stretches of freezing temperatures, we recommend these options, below, based on how many gallons your pond holds. The aerator-deicer combo will give your smaller water garden the one-two punch it needs to vent harmful gases and keep your fish safe, while the more powerful KoiAir will sufficiently aerate larger ponds:

Q: When should I remove my fountain?
Ray – McDermott, OH
A: Among your fall-preparation chores is removing the fountain and storing it for winter, particularly if you live in an area that endures freezing temperatures. Why? When ice forms, the cold stuff might damage the float. Or it could create a barrier that prevents water from passing through the spray nozzle, causing your fountain run dry and destroying your motor.
Your best bet: Remove the fountain before the ice begins to form. Sure, you could wait until a thin layer develops and then remove it—but that means you have to get wet and messy when it’s freezing. Not fun. Get a jump-start now before temperatures get too frigid.
Here are four easy steps to pulling out and storing your fountain for the winter:
- Pull the Plug: Turn off the power to the fountain and pull it ashore. Most units have a quick disconnect at the motor that allows you separate the fountain from the main power cord.
- Scrub Down: Wash down the fountain and float assembly to remove any algae or debris that has accumulated over the season. If you have a pressure washer, use it. It’ll make short work of even the dirtiest fountain.
- Electrical Check: Inspect wiring and electrical cables for signs of wear or damage. If your fountain has lights, check for burned out or damaged bulbs and lenses.
- Safe Storage: Once your fountain is cleaned and inspected, store it in an upright position in a climate-controlled location, like a heated pole barn or garage, until spring.
Now that it’s out and cleaned, you might want to consider sending your fountain to a licensed repair facility for routine maintenance tasks, including oil changes and/or seal replacements. Be sure to read through your user’s manual for special instructions and maintenance plans to keep your fountain running at its very best.
If you don’t plan on using the pond for ice skating or other winter recreation, now is a great time to install an Airmax® Aeration System to keep your pond oxygenated and healthy through the winter months. The aerator will circulate the water while keeping a hole in the ice surface, which will bring oxygen in and allow toxic gases to escape.
