A: When it comes to doing chores at the pond, it is easy to let your guard down this fall. Thanks to your hard-working bacteria, the water is clean and clear with minimal algae, and your fish are happy. You have nothing to do but coast into winter and hibernate until spring.
Not so fast.
As water temperatures drop, those bacteria and algaecides stop fighting off excess nutrients and cold-temperature plant growth. They are no longer effective at their jobs, and so you need to step in and help. Here's what you can do to maintain pristine water quality over the winter.
- Add Some EcoBoost PRx: Formulated to bind organic debris suspended in the water, EcoBoost PRx helps to clear water and enhance beneficial bacteria. It also provides more than 80 trace minerals to fish, keeping them well over the winter. EcoBoost has no temperature restrictions, so you can use it all year round. Simply mix the powder with some water in a pail and pour it in the pond.
- Tint with Pond Dye: During the cold temperatures and even iced-over conditions your pond's bottom can still be exposed to sunlight. Pond Dye can be used year-round – winter included – to shade your pond from the sun's UV rays. The dye also imparts a dramatic hue to the water, giving it a great look when it ices over.
- Aerate and Oxygenate: You can also improve water quality through the winter by keeping the oxygen levels up and water circulating. If you are not going to use the pond for ice-skating or hockey, we recommend you use a subsurface aerator, like the Airmax Aeration Systems. The system will keep the air bubbles flowing throughout the water column while maintaining a hole in the ice for gas exchange. If you have a fountain running, remove it and store it for the winter. Ice can damage the motor in the pump.
Before you hibernate for the winter, spend a few hours out at the pond to prepare it for winter. When you look out on a crystal clear pond in January, you'll be happy you did!
