Evolution Aqua’s Tips: Prepare your Pond for Winter 

As the temperatures drop and the colder months approach, it’s essential to prepare your pond for winter. By taking a few preventative measures now, you can ensure your pond stays healthy and thrives even when the weather isn't in your favour.

Here are Evolution Aqua’s top tips for getting your pond winter-ready and the products that can make this transition easier:

 

1. Clean and Clear Your Pond
Autumn often means falling leaves and debris, which can quickly accumulate in your pond. Organic matter like leaves, uneaten fish food, and other debris can break down, leading to harmful spikes in ammonia and build-up of nitrates, negatively affecting water quality.

What to do:
Use a net or skimmer to remove debris regularly. For more thorough cleaning, consider using a pond vacuum to clear out any buildup on the bottom of the pond.

 

2. Check and Maintain Your Equipment
Winter can be hard on your pond equipment, if not installed within a filter house, so it's crucial to ensure everything is in top shape. Evolution Aqua's pond equipment, such as filters, UV units, and water pumps, are designed to be long-lasting but need proper care during colder months.

What to do:
 Disconnect your detox system and store indoors in a dry place to avoid any frost damage during the winter months and be sure that it is fully drained.

 UV Clarifiers: Clean your evoUV or evoUV Ti. Be sure to follow the maintenance instructions in the product manual. The unit must be fully frost protected, if you’re able to bypass your UV it can be good practice to drain the UV unit.

 Water Pumps and Filters: Clean your Varipump and check for any debris in the filters. Ensure you follow the product guide for winter maintenance. We’d recommend running your filter for as long as possible to prevent freezing, insulating your filter and pump can be good practice if it is kept outdoors against the elements. However when reaching temperature extremely low, drain your filter to prevent filter freezing solid.

By performing this equipment check, you'll ensure everything is in optimal condition for the next season.

3. Install a Pond Heater (or Consider Alternatives)
Keeping your pond from freezing over is critical, especially in areas with long and harsh winters. A pond heater can help to maintain an opening in the ice, allowing oxygen to enter and preventing harmful gases from being trapped, which can harm fish.

If a pond heater isn't in the budget, consider these alternatives:

 Float a pool noodle or a rubber ball on the water’s surface to prevent complete freezing.

 Set up a windbreak around your pond to help reduce wind chill, which can cause rapid heat loss. Hardy plants, wooden panels, or even snow fencing can be great wind barriers. Evolution Aqua's air pumps are also a great option for keeping water circulating and preventing ice from forming.

What to do:
 If using a pond heater, install it before the coldest temperatures arrive to ensure it functions effectively.

Regularly check the pond surface for ice formation and remove any that accumulates if you are using alternative methods.

 Consider positioning air pumps strategically to create circulation in areas most prone to freezing, ensuring your fish have a healthy environment throughout the winter.

 

4. Reduce Fish Feeding
Fish naturally eat less as temperatures drop. Their metabolism slows down, meaning they need less food. Continuing to feed your fish too much can result in excess waste, which contributes to poorer water quality.

What to do:
 Gradually reduce feeding when the water temperature drops below 10°C.

Switch to Evolution Aqua's wheatgerm food, which is lower in protein and easily digestible, ensuring your fish receive essential nutrients without straining their system. Eventually, when the temperature drops below 4°C, you will only need to feed your fish 1-2 times a week until spring.

 

5. Monitor Water Levels and Quality
Cold air leads to lower water levels, which can damage your pond equipment if not properly monitored. Additionally, maintaining water quality is just as important during winter as it is in summer.

What to do:
Keep an eye on your pond's water level, topping up, with a carbon filter, when necessary to ensure pumps and filters remain submerged.

Regularly test the water quality for pH, ammonia, and nitrite levels. Use test kits to keep an eye on these parameters and make adjustments as needed. Winter might reduce the activity in your pond, but ammonia spikes can still occur due to decaying plant material or fish waste.

 

6. Prepare Your Plants
Aquatic plants are an integral part of your pond ecosystem, but not all plants handle cold weather the same. Hardy varieties will survive in deeper water, while tropical or delicate plants may need extra care.

What to do:
 Trim back any dead or dying foliage.

 Move hardy plants, like water lilies, to the deeper areas of your pond where they are less likely to freeze.

 For more delicate plants, consider moving them indoors to an aquarium or water feature until spring.

 

7. Use PURE Products to Maintain Water Quality
Even in the colder months, maintaining beneficial bacteria levels in your pond is essential. While the natural bacteria and enzymes contained within our PURE Pond products are less effective at temperatures under 10°C, using the right products can help keep your pond healthy.

 Use PURE Sludge Remover: As you move into the winter months, this product will help break down any accumulated sludge at the bottom of the pond, which is common during winter due to reduced biological activity.

 Boost Beneficial Bacteria in Spring: The cold weather can drastically affect the beneficial bacteria in your pond and on your media. Using Filter Start Gel as you transition into spring can provide the needed boost to kickstart your pond’s ecosystem.

What to do:
 Use PURE Sludge Remover in the weeks leading up to winter to manage sludge levels effectively before temperatures drop.

 Monitor water temperature and use Filter Start Gel once temperatures begin to rise, usually around late March or early April, to replenish beneficial bacteria and support a healthy pond environment.
