Q: I bought an aeration system this year. What maintenance should I be doing?

Gary – Saginaw, MI

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 Pond Logic® SilentAir™ Piston Compressor Air Filter; for shallow-water units, use the Pond Logic® 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 Pond Logic® 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.

What is the thermocline? | Ponds & Lakes Q&A

Q: What is the thermocline?

Q: What is the thermocline?

Walt – Cedar City, UT

A: Have you ever swum in a pond without a bottom aerator and felt colder water near your toes and warmer water on top?

You’ve experienced the thermocline.

Simply put, the thermocline is a layer of water between the warmer, surface zone and the colder, deep-water zone.

In ponds and lakes in the summertime, a natural phenomenon called stratification occurs when warm, less-dense, oxygen-rich water sits on top of colder, denser, oxygen depleted water. The thermocline separates the warm layer—the epilimnion —and the cold layer—the hypolimnion. In this stable system very little mixing of the layers occurs, particularly in calm weather.

Fish and other underwater critters (including beneficial bacteria) have trouble with this stratification. As summer marches on, your finned pals have less and less oxygen available below the thermocline, so they have to come closer to the surface to get their needed O2 supply. That means less room for them to swim. It also means your beneficial bacteria below the thermocline become oxygen-starved, which could result in algae growth and odor.

Thank goodness for aeration.

Bottom diffuser aeration, like Airmax® Aeration systems, prevents your pond or lake from stratifying by churning and mixing the temperature layers. The tiny bubbles created by the diffuser force the cooler oxygen-starved water to the pond’s surface where it becomes pumped up with O2. The warmer, oxygen-rich water then drops down, fueling the beneficial bacteria.

The result is an eliminated thermocline and higher oxygen levels throughout the water column.

It’s critical, however, that your system be sized correctly for your pond so the aeration is uniform throughout. If you currently have an aeration system running and you’re not sure if it’s doing its job, take your pond’s temperature. Using a thermometer and string, measure the temperature of the water every 24 inches down in various locations in your lake. If you find that you have more than a few degrees difference in your vertical readings, you’re probably under-aerating your pond.

But once you get your aeration system dialed in, your fish will once again have full access to the entire body of water, and your beneficial bacteria will have the opportunity to grow and thrive.

Call us if you need help mapping the aeration system in your lake. We’re happy to help!

My pond is spring fed. Does aeration do anything more for my pond than what the fresh water does? | Ponds & Lakes Q&A

Q: My pond is spring fed. Does aeration do anything more for my pond than what the fresh water does?

Q: My pond is spring fed. Does aeration do anything more for my pond than what the fresh water does?

Tom – Eden Prairie, MN

A: You gotta love a spring-fed pond. Rather than being volume-fluctuating catch basin for precipitation runoff (and pollution in some cases), it’s filled by a spring or ground water. That means the water level stays fairly consistent regardless of rainfall—and that’s a definite plus if you’re using the lake for recreation or watering livestock.

As great as they are, spring-fed ponds do have their challenges. They’re prone to thermocline, which is when water forms layers or stratifies depending on the water temperature. And even though spring water flows into the lake or pond from the underground aquifer and provides good water exchange, it is typically low in dissolved oxygen and not moving enough to circulate the water column.

Just about every pond or lake can benefit from aeration—including those that are spring fed. Here’s how an Airmax® Deep Water Aeration System can help your pond:

  • Circulates the Water: Rather than develop pockets of cold, oxygen-depleted water, a pond with an aeration system moves the water both horizontally and vertically.
  • Prevents Thermocline: During the summer in a pond that’s not properly aerated, the water at the top is warmer and full of oxygen while the deeper water remains cooler and nutrient-rich. Aeration churns the water, allowing the shallow and deep water to mix.
  • Infuses Oxygen into the Water: Your lake and its underwater inhabitants need oxygen to survive, and aeration pumps that O2 into the water while releasing dangerous gases, like ammonia, at the surface.
  • Promotes Muck Digestion: Beneficial bacteria thrive on oxygen, too, and those tiny microorganisms eat through muck and debris that has collected in your lake—ultimately creating a cleaner pond.

For those readers who have an aeration system in place but are unsure if the water is properly aerated, we suggest taking temperature readings at multiple depths and in different areas of your pond and recording any extreme variations, which indicate a lack of circulation from your aeration system.

I love the look of a fountain but does it provide sufficient aeration for my pond? | Ponds & Lakes Q&A

Q: I love the look of a fountain but does it provide sufficient aeration for my pond?

Q: I love the look of a fountain but does it provide sufficient aeration for my pond?

John – Wapakoneta, OH

A: Sitting out on the deck and viewing a beautiful fountain display as well as hear that relaxing sound of water is pond enjoyment to us. Having a fountain in your pond is a great way to add tranquility to your home. What more could you ask for?

Many people are drawn to a fountain’s show-stopping appeal, but will they aerate a pond as well? The answer to this really depends on a couple factors: the pond’s depth and the type of fountain pattern.

Pond Depth: Fountains can be great aerators when the pond has less than 6′ of depth. The reason for this is because the best way to aerate is to circulate the whole body of water at the same time. A fountain will only draw water from the top of the water column, which is water that already contains oxygen from the air to water oxygen transfer. The pond’s bottom will remain untouched if it is deeper than 6′. If your pond is less than 6′ deep, then all you have to worry about is the spray pattern.

Fountain Spray Pattern: The spray pattern of a fountain makes a huge difference in how much aeration is produced. Usually the more decorative the spray pattern, the less likely it is to aerate your pond properly. This is because more energy is spent on creating the decorative pattern than there is moving the water. The best spray pattern to use for a fountain is a “V” patterned fountain like the Kasco VFX series fountain.

Because of the varying fountain choices there are some rules of thumb to go by. When using a fountain for aeration purposes, you want around 1.5HP per acre. If using a fountain only for decoration, go for 1 HP per acre.

If your pond is deeper than 6′ of depth, than the best method of aeration is an Airmax® Aeration System. The Airmax® Aeration System will pump air to the diffuser plate located at the bottom of the pond, and the resulting column of rising bubbles lifts and aerates the water. By starting from the bottom, this will ensure that the whole body of water is properly circulated as well as aerated. Airmax® Aeration Systems have lower operating costs than running a fountain 24-7.

How do I know which aeration system is right for my pond? | Ponds & Lakes Q&A

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

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!

Is it too cold to treat my pond with the ClearPAC® PLUS? | Ponds & Lakes Q&A

: Is it too cold to treat my pond with the ClearPAC® PLUS?

Q: Is it too cold to treat my pond with the ClearPAC® PLUS?

Steve – Denham Springs, LA

A: The Pond Logic® ClearPAC® and ClearPAC® PLUS combine PondClear™, Algae Defense®, EcoBoost™ and Nature’s Blue™ Pond Dye to combat algae and suspended debris and beautify your lake or pond. Some components of this super-pack have temperature limitations while others can be used year-round. Let’s take a closer look at each one.

PondClear™ (and MuckAway™)

Beneficial bacteria that break down muck and suspended debris, such as those found in PondClear™ (and MuckAway™ in ClearPAC® PLUS), can be used when water temperatures rise to more than 50° Fahrenheit or so. Though that temperature is not a definitive starting point, the bacteria will become more effective as the temperatures rise. Bottom line: When your underwater thermometer tops 50°, it’s time to start treating your pond or lake with ClearPAC®.

Algae Defense®

This algae-destroyer can be used to treat troublesome floating filamentous algae, bottom growing chara or the planktonic algae as long as it’s green and growing, and the water temperature in your pond or lake is above 60° Fahrenheit.

EcoBoost™

EcoBoost™, which is a bacteria booster rather than an actual bacteria, has no temperature restrictions so it can be used year-round to bind phosphates that find their way into your pond or lake. You can use EcoBoost™ throughout the spring to give you a head start on pond season.

Pond Dye

The final ingredient in the Pond Logic® ClearPAC®, Nature’s Blue™ Pond Dye, is not temperature-sensitive, so it can be used year-round to give your pond or lake that aesthetic appeal throughout the winter months. And if spring storms are preventing you from standing next to your pond pouring in a quart of dye, try Pond Dye Packets—all you do is toss the water-soluble packet into the water and head back to your warm and toasty home!

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

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

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.

1. Replace Your Air Filter

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 Pond Logic® 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.

2. Check Your Diffusers

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 Pond Logic® ProAir™ Membrane Diffuser Sticks.

3. Rebuild Your Pistons

Was your aeration system producing less air last year than the season before? The piston may be wearing out. Get out your Pond Logic® 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® Aeration System Product Manual for additional tips and maintenance instructions.
