Q: What kind of aeration maintenance should I be doing this season?
Bill- Cannon Falls, MN
A: With spring in full bloom, now is the time to tune up your aeration system. It doesn’t matter if you’re turning it back on after the long winter or if it has been running since last year – your aeration system is a very important in keeping your pond healthy, so keep it humming.
Spring Start Up
If you’re turning your aeration system back on in the spring, the airlines traveling from the air compressor to the diffuser plates may contain ice. Those frozen blockages will prevent oxygen from flowing into your pond. To break up the ice, follow these three steps:
- Measure 1 cup of isopropyl alcohol for each airline that runs out a plate.
- Turn on your compressor to push the alcohol through line and free any ice blockages.
- Follow initial startup procedure to avoid “shocking” in the pond.
Every week throughout the pond season, check the side cabinet’s air filter for debris, particularly if you live in a dry, dusty environment. Clean your air filter as needed because when it becomes clogged, your compressor and pump are forced to work harder – which means more wear and tear on those moving parts. When you clean the filter, make sure it’s completely dry before placing it back inside the cabinet.
Every 3 to 6 Months
Several times a year, block out some weekend time to perform these maintenance tasks:
- Replace the air filter. Although you’ve been cleaning your air filter regularly, you will need to replace it every three to six months. We recommend Airmax® SilentAir™ RP Series Compressor Air Filter for Pond and Lake Series Systems. While you’re in the cabinet, make sure the aeration unit’s cooling fan is operating properly.
- Check your pressure gauge. For Pond and Lake Series Aeration Systems, mark pressure gauge upon initial start up and check it every few months. Normal operation will range between 5 to 10 psi.
Every 12 to 24 Months
In addition to cleaning your aerator’s membrane sticks, you should also plan to do the following tasks depending on what aeration system you have installed in your lake or pond:
- Shallow Water Series: Install Airmax® SilentAir™ Diaphragm Compressor Maintenance Kit once every 12 months. It contains washers, gaskets and other wear-and-tear parts that will need to be replaced regularly.
- Pond Series and Lake Series: Every 18 to 24 months, install a piston maintenance kit, like our Airmax® SilentAir™ Piston Compressor Maintenance Kit. It also contains a range of parts that will need to be replaced.
Your aeration system requires regular maintenance to keep it performing at its best. Doing so will extend the lifespan of the unit and ensure your system is running as efficiently as possible.
