Q: How do I get my aeration system ready for winter?

A: Operating your aerator year-round delivers a boatload of benefits to your pond or lake. The water movement created by the aerator forms a hole in frozen winter ice, allowing for gas exchange and keeping water open and available for visiting wildlife. Below the surface, it helps to break down leaves and debris, which means less cleaning and easier maintenance come spring. Aeration also circulates the water column, infusing it with oxygen for your fish and plants.

Unless you plan on doing winter activities on your pond, like figure skating, ice fishing or playing ice hockey, we highly recommend running your Airmax® Aeration System all year long. Here are five winter tasks to add to your to-do list:

  1. Move your diffuser plates to shallower water. Following your aerator manual’s recommendations, move the plates from the deepest areas of your pond to shallower areas. This will give your hibernating fish a warmer place to hunker down when the water temperatures get especially chilly. When the plates are closer to the surface, they will also help to keep a hole open in the ice. If you have a larger system, plan to completely shut down some of the valves.
  2. Clean filters and inspect your compressor. Have you cleaned your air filter in the past three to six months? Have you checked your intake pre-filter? If not, they likely need some attention—and possible replacement if it’s been too long. Also consider installing a maintenance kit to keep your compressor running in top condition. The video below demonstrates compressor maintenance for PondSeries™ Aeration Systems.

  3. Check the aerator regularly throughout the winter. After a heavy snow or a storm, head out to the pond and inspect your aeration unit. Remove snow that has accumulated around the unit, particularly any that’s blocking the air discharge vent. If you lost power during a storm, check your GFCI; you may have to reset it.
  4. Keep alcohol on hand. In case condensation causes your airlines to freeze over the cold months, keep some isopropyl alcohol on hand to defrost them. It’s easy: Use 1 cup isopropyl alcohol in the airline running out to each plate. Turn on the compressor to push the alcohol through the line and free any ice blockage.
  5. Be smart and safe. When your aerator is on during the winter, the ice that forms can be thin and uneven. The constant friction created by the aerating water weakens the ice that forms, and that could be downright dangerous. Make sure you post a “Danger—Thin Ice” sign and keep safety equipment out by your pond. A life ring, rope, blankets and a first aid kit are critical items to have on hand.

If you do plan to remove your aeration system for the winter, here’s what we recommend: First, unplug the system. Then disconnect compressor flex-tubes from the airlines and cover the airline ends with winterization caps to prevent debris from entering airline. Move the cabinet and compressor inside to keep it dry.

A: Congratulations on your purchase of an Airmax® Aeration System—and good for you for thinking about regular maintenance, which will keep it operating well for years to come. Here are some things to inspect on a routine basis:

  • Check Your Cooling Fan and Pre-Filter: Regularly clean out your pre-filter and check to see that the fan is indeed operating. Hot air should be blowing out, not air being pulled in. An easy way to remember to do this is to always check your fan and shake off your pre-filter when you cut your lawn.
  • Check Your Air Pressure: Check to see that your air pressure has not risen or dropped significantly. Normal operation will range between 5 and 10 psi. Also be sure to check your pressure relief valve to make sure no air is escaping.
  • Check Your Air Filter: Clean and replace your air filter every three to six months, depending on your environment, and do not place a wet air filter back into the unit. For deep-water units, use the Airmax® SilentAir™ Piston Compressor Air Filter; for shallow-water units, use the Airmax® SilentAir™ LR Series Air Filter.
  • Purge Your Membrane Sticks: Once per year, purge your membrane diffuser sticks. See the product manual for additional instructions.
  • Use the Maintenance Kit: Finally, be sure to use your maintenance kit for the system you have installed. For shallow-water systems, use the Airmax® SilentAir™ Diaphragm Compressor Maintenance Kit every 12 months to keep your diaphragm compressor running its best. For deep-water systems, use the Pond Logic® SilentAir™ Piston Compressor Maintenance Kit every 24 months to keep your piston compressor humming.

Remember, if you have any questions, need additional information or want to read through some troubleshooting tips, refer to your product manual.
