Q: How do I know which aeration system is right for my pond?

Tim – Warren, OH

A: Yes, aeration systems can be confusing. If you’re not used to working with calculations that involve a lake’s surface area, depth and shape, deciding which system fits your fish pond can be a complicated matter.

Well get out your tape measure and calculator, because we’ve made the process easy. Here’s what you need to know to pick the right aeration system for your needs.

Pond Size

First, you’ll need to determine the size of your pond or lake so you can select a powerful enough aeration system to handle it. To calculate its surface area, measure the length and the width, multiply them, and then divide that number by 43,560. Each aeration system lists the pond surface area that it can handle on the package for easy selection.

Pond Depth

Once you know your pond or lake’s surface area, you then need to figure in its depth. It plays an important role in the system compressor’s efficiency and aeration area—the deeper the pond, the more area one diffuser can handle; the shallower the pond, the less area it can handle.

Look for the system that will handle the surface area at the depth of your pond. Ponds less than 6 feet deep will benefit from an efficient shallow water system, like the Airmax® Shallow Water Aeration System. It allows for multiple aeration plates that can be spread across the pond for more efficient aeration where the lack of depth reduces the area a diffuser can handle.

Pond Shape

Finally, take a look at your pond’s shape. If you have a round pond, it’s relatively easy to fit an aeration system, like the Airmax® Deep Water Aeration System, based simply on its size and depth. If you have a long, narrow pond or one with odd shapes or coves, however, you may require additional diffusers for optimum circulation.

Still having a problem figuring out the aeration puzzle? Let us help! We can look up your pond via satellite and size the aeration system for you along with a layout for diffuser placement. Just give us a call or shoot us an email!

## How do I restart my aeration system after storing it for the winter? | Ponds & Lakes Q&A

Q: How do I restart my aeration system after storing it for the winter?

Allan – West Jordan, UT

A: Pond season is quickly on its way—and wouldn’t it be nice to restart your aeration system with the flip of an on-off switch? Unfortunately, it’s not quite that easy. If the aerators in your fish pond or lake were shut down for the winter, they’ll require some basic inspection and maintenance to ensure they’re ready to run.

Don’t worry. We’ve made the annual chore easy with these five aeration system maintenance tips.

As part of your overall aeration system maintenance, the first thing to do is take a look at your air filter. Is it caked with dust and debris? Does it need to be replaced? A new air filter, like Airmax® SilentAir™ Air Filter, should ideally go in every six months or every three to four months if it’s in a dusty environment. A clean filter allows clean air to pump through the compressor, which means it will endure less wear and tear—and last longer.

You can try to clean the air filter, but its performance will still be reduced (note: never place a wet element back in the filter!). Many times, it’s easier to simply replace the filter element rather than the entire filter unit.

Next, take a look at your diffusers, particularly if it has been a few years since you’ve brought up the diffuser plates. Give them a light cleaning and inspection to make sure you see no cracks or tears. When running, a properly functioning diffuser should release small air bubbles; large bubbles may indicate some damage. If the diffuser sticks are beyond repair, replace them with Airmax® ProAir™ Membrane Diffuser Sticks.

Was your aeration system producing less air last year than the season before? The piston may be wearing out. Get out your Airmax® Piston Compressor Maintenance Kit and repair or replace any parts that are worn or malfunctioning. Quick repair of the compressor will ensure your fish pond or lake gets proper aeration all summer long.

4. Slowly Flick the Switch

Once you’ve performed these maintenance chores, introduce the aeration slowly. Doing so at full force may cause the water to mix too quickly, which can cause your fish to stress. Instead, run the system for an hour the first day, two hours the second day, four hours the next day—essentially, doubling the running time each day until your run time reaches 24 hours.

5. Check the Manual

Of course, if you get stuck or need technical guidance, see the Airmax® Pond Series™ Aeration System Product Manual for additional tips and maintenance instructions.

## How Do I Revive My Aeration System After Storing It For The Entire Winter? | Ponds & Lakes Q&A

Q: How Do I Revive My Aeration System After Storing It For The Entire Winter?

John – Sumner, IA

A: If you turned your aerator off and stored it for the winter they are a few quick steps you can take to have your aeration system prepped and installed for the spring. If your winter has been anything like ours in southeastern Michigan, spring already seems upon us.

Here’s 4 ways to prep and install your aeration system for spring.

1.)  Change the Air Filter: The air filter is vital for providing clean air through the compressor. With a clogged air filter, performance diminishes and over time can cause irreversible damage to the compressor. We recommend changing your air filter every 3-6 months depending on the environment.

2.)  Check for Air: Before installing the unit and connecting airlines it is best to do a quick check for air. Turn the unit on and ensure air is coming out of the flex hose(s). If you have a multiple diffuser plate system, make sure that the valves are not completely shut off. In the event where air is not coming from the flex hoses, you may need a maintenance kit to replace worn seals.

3.)  Reinstall the unit: To reinstall the unit, you’ll want to reposition the cabinet so it is sitting level, reconnect the airlines and plug it in. Adjust the airflow as needed, which you’ll need to do anyway if you have multiple diffuse plates. Adjust the flow so each air plate receives equal amounts of airflow and keep in mind that longer runs and deeper plates will require more airflow to operate than shallow plates and shorter lines. It usually takes a few minutes between adjustments to see the effect at the diffuser plant, so be patient!

4.)  Proper start up: Introduce your aeration system slowly in the beginning, and gradually increase its running time each day. Start by running it for an hour the first day, two hours the second day, doubling the amount of time each day until you can successfully run it for 24 hours. If you run the system immediately for 24 hours upon returning it to the pond, you could cause the warm and cold layers of water to mix too quickly which may harm fish.

These quick steps will ensure your aeration system is back up and running to keep your pond clean, clear and healthy for years to come.

## How can I keep mosquitoes away from my pond? | Ponds & Lakes Q&A

Q: How can I keep mosquitoes away from my pond?

A: Buzzing, biting, irritating mosquitoes are the bane of pond and lake owners. Besides causing itchy welts, these little blood-sucking insects can transmit dangerous and deadly diseases, like malaria, dengue, yellow fever, West Nile virus, dog heartworm, and equine encephalitis.

Before we get into how to eradicate the little pests, let’s first learn their life cycle.

Eggs, Wigglers and Tumblers

Mosquitoes begin life as tiny eggs on the surface of fresh or stagnant water. Twenty four to 48 hours after they’re laid, they hatch into mosquito larvae, a.k.a. “wigglers.” The little half-inch larvae live on the water surface for four to 14 days, and they eat algae, plankton, fungi and bacteria and other microorganisms that float by. As the little wigglers develop, they molt four times and, after the fourth molt, they go into their pupa stage. Mosquito pupae, commonly called “tumblers,” live in the water from one to four days. When they emerge from their pupal case, they’re full-fledged adults – and the females are ready to suck your blood.

Deterring Mosquitoes

To crush these tiny vampires, your best bet is to prevent the females from laying eggs in the first place. Here’s what we recommend:

•  Remove the habitat: Because mosquitoes prefer to lay their eggs in stagnant water, cut down dead debris around the edge of the pond with your Weed Cutter and Pond & Beach Rake as these calm, secluded areas are perfect for developing wigglers and tumblers. Also drain containers with standing water, like buckets, gutters and ditches, and regularly change the water in animal troughs, pet dishes and bird baths.
•  Keep the water moving: In your pond or lake, use an aeration system, like the Airmax® Large Lake Aeration System, to keep the water moving. The females won’t want to lay their eggs in agitating water, so this preventive measure can cut down tremendously on the mosquito population.
•  Resort to mosquito dunks: If all else fails and you get swarmed whenever you get within 50 yards of your lake or pond, Mosquito Dunks® or Mosquito Bits® provide an excellent temporary solution. These mosquito destroyers contain Bt-israelensis (Bt-i), a specially formulated biological pesticide just for mosquitoes. They’re safe for use around fish and plants, and they provide relief for up to 30 days.

Of course, you may not be able to completely eradicate the mosquitoes, but you can at least suppress them using these measures. You can also contact one of the state, county or city mosquito control organizations, which can help with larger-scale efforts. For more information, check out the American Mosquito Control Association at www.mosquito.org.

## Why Does Algae Keep Growing In My Pond, Even After I Treat With Algaecides? | Ponds & Lakes Q&A

Q: Why does algae keep growing in my pond, even after I treat with algaecides?

Cathy – Bagley, WI

A: Algae seems to take on a life of its own sometimes, doesn’t it? Once that green slimy, stringy or seaweed-looking stuff crops up, it keeps growing and growing until you wind up with a messy situation in your pond or lake. Even if you treat it with algaecides, it still grows back.

Turns out that all these tiny plants need to grow is sunlight and food source – both of which are abundant during certain sunny times of year and when there’s a healthy mix of detritus built up along the bottom of the lake. To make things worse (or better for the algae!), when a pond is treated with chemicals, the process just adds dead algae to the pond, which is actually a food source for the growing algae.

Rather than battle this green monster after it has a foothold, it’s best to take a proactive approach. After you verify that you’re dealing with algae and not weeds (read here for a quick lesson on chara and other types of algae), we recommend you follow these four all-natural steps for preventing algae attacks:

1. Use Aeration: Aeration systems, like Airmax Aeration®, circulates debris that has accumulated in the lake or pond so it doesn’t settle at the bottom and become algae food. Aeration also spreads the debris throughout the water column, making it more accessible to beneficial bacteria that break it down.

2. Use Natural Bacteria: Natural beneficial bacteria, such as Pond Logic® PondClear™ Beneficial Bacteria, power through nitrates, breaking down fish waste, leaves and other organics that accumulate in the pond. This naturally improves the water clarity as the bacteria devour the sediment.

3. Use EcoBoost™: Pond Logic® EcoBoost™ Bacteria Enhancer is an innovative product that binds algae-feeding phosphates in ponds and stimulates the growth of essential beneficial bacteria, which are essential when controlling algae in your lake or pond.

4. Use Pond Dye: Because algae thrive in sunlight, Pond Dye filters those rays and stops them from reaching below the surface, thereby preventing algae from growing. Plus, the cool colors mask the soupy green hue of the algae.

We can’t guarantee your algae problem will disappear, but if you follow these steps you’ll be creating a pond that’s inhospitable to algae invaders.

I’m going to use my pond for skating over the winter. What do I need to do to store my aeration system?
Wayne – Pontiac, MI

One of the great joys of a backyard pond is its four-season versatility. After three seasons of aesthetic satisfaction, there’s nothing better than strapping on a pair of skates and hitting the water when it hardens up for the winter. But before the temperatures drop, your aeration system demands some seasonal attention.

As a rule, it’s okay to keep your aeration system in operation until ice begins to form. When that day arrives, it’s time to shut the aerator off. At that point, you’ll want to put the compressor and its housing in a cool, dry place to avoid exposure to the elements, where dramatic weather changes can cause condensation that may cause damage. To accomplish this step, first disconnect the compressor from the airline. Be sure to cap the exposed end of the airline, leaving the remaining line buried, and diffuser plates in the pond.

When the aeration season is over, it’s a great time to perform regular maintenance. Consider changing your air filter. Choose a high quality replacement, like our Airmax® SilentAir™ Complete Filter Assembly, and install new Airmax® SilentAir™ Replacement Air Filter Elements if your filter is in good enough shape for another season.

If you’ve noticed that your compressor is producing less air than it should, you may want to consider the use of a Maintenance Kit to boost the compressors performance or inspect the diffusers and replace any damaged diffuser membranes. If you’re still using air stones, it’s the perfect time to upgrade to Airmax® Membrane Diffuser Sticks, which are easy to install, and virtually maintenance free.

Happy skating.
