Isn’t the waterfall enough aeration for my pond? | Decorative Ponds & Water Gardens Q & A

Q: Isn’t the waterfall enough aeration for my pond?

Q: Isn’t the waterfall enough aeration for my pond?

Staci – Bethel, VT

A: As your waterfall gurgles and churns gallons of water, it would certainly appear that your pond is getting plenty of aeration. All that action does, in fact, help with gas exchange and infuse oxygen into the water. But it isn’t always enough, especially if you run your waterfall pump for a short time during the day.

If a pond isn’t aerated enough, expect to see these telltale signs:

  • Algae Battles: Algae thrive in calm water that’s devoid of – and in need of – oxygen and beneficial bacteria. If you regularly fight algae blooms, that means your pond is out of balance and could use some additional oxygen and movement throughout the entire water column.
  • Oxygen-Starved Fish: Fish that need more oxygen will hang out beneath your waterfall, where oxygen supplies are the densest. They may also be coming to the water surface, gulping and gasping for breaths of air because there’s not enough in their environment.
  • Too Many Fish: The general rule for a fish population in a pond is to allow 1 inch of fish per square foot of surface area. If you have too many fish, or your existing population has outgrown their space, aeration is critical to their health and well being.
  • Stagnant Water, Mosquito Boom: Is the water stagnant in certain areas of your pond? Are you suffering through a mosquito boom in your backyard? These little pests prefer to lay their eggs and raise their young in still water – so you might have created a perfect mosquito habitat!
  • Muck Accumulation: Decomposing plant matter and fish waste build up when the water is still and your biological filtration system can’t keep up. That muck feeds the algae blooms, which create more muck.

Do any of these ring true? If so, your waterfall or stream is not providing enough aeration for your pond. An aeration system can help. The Airmax® PondAir™ Water Garden Aeration Kit is designed for smaller water gardens up to 2,000 gallons and The Pond Guy® Water Garden Aeration Kit is designed for water gardens and koi ponds that are up to 4,000 gallons. Both whisper-quiet systems can be run 24 hours a day, seven days a week, providing your finned pals and beneficial bacteria plenty of oxygen and water movement.

I’m starting my pond up for spring. Do I need to leave my aerator running? | Decorative Ponds & Water Gardens Q & A

A:  As winter gives way to the sunny days of spring and summer, you should absolutely plan to leave your aerator running. That water-churning system that benefits your pond over the cold months will also benefit your pond during the summer—and then some.

Winter Bubbles
As most pond owners know, an aerator, like The Pond Guy® Water Garden Aeration Kit, used during the winter serves two purposes: to aid de-icers in creating and keeping a hole in the ice, and to circulate water to vent gases when filtration systems are shut down for the season. The circulation also encourages contact between the water and the environment, which will increase the dissolved oxygen level in your pond.

Summer Aeration
In the summer, aeration provides some extra benefits. Besides moving the water and boosting the oxygen level in the water molecules, aeration does these things:

  • Circulates the water in areas where filtration may not reach, preventing stagnation and low-oxygen pockets in your pond. Filtration systems only move the top of the water column, not the bottom. But an aerator works from the bottom up, circulating the water and increasing dissolved oxygen levels throughout the pond.
  • Keeps oxygen distributed throughout the water column much more efficiently than a water feature, like a waterfall, spitter or stream.
  • Provides bubbly camouflage in which fish can hide.
  • Stirs up debris on the pond bottom, allowing it to be filtered out or broken down by beneficial bacteria. If that debris is allowed to collect, muck will build up and release harmful gases as the organic materials decompose.
  • Helps beneficial bacteria thrive and flourish, thanks to the circulation and oxygen. Higher oxygen levels stimulate and increase the number of natural aerobic bacteria living in your pond. More bacteria means more efficient filtration.

As you’re prepping your pond for spring, jump start the season with DefensePAC® Pond Care Package. It contains Oxy-Lift™ Defense®, Nature’s Defense®, Clarity Defense®, Muck Defense® and Seasonal Defense® — everything you’ll need for spring cleaning, bacteria boosting and water clarifying.

Aeration definitely has its benefits, no matter what the season. If you want a balanced ecosystem with healthier fish and plants, keep your aerator running.

What is the optimum water temperature for my pond, and when should I worry that it’s too hot? | Decorative Ponds & Water Gardens Q & A

A: “Room temperature” isn’t just for humans. Fish and pond critters prefer particular underwater temperatures, too. In fact, and a high-temp living environment can even affect their health and well-being. Warm water holds less oxygen than cool water, so they’ll be literally gasping for breath if it gets too hot.

As the air temperature heats up this summer, the water temperature in your pond will increase, too, so it’s critical to keep an eye on it as the mercury rises. Use your Floating Pond Thermometer to test the waters. The best water temperature for your aquatic pals is between 68° and 74° Fahrenheit (pretty close to an ideal air temperature for humans).

If your thermometer tops 85°F, you’ll need to cool your water. Here’s what we recommend:

  • Add Aeration:Make sure you have your aeration system, like the Airmax® PondAir™ or KoiAir™ Aeration System, up and running. It’s like an underwater fan for your koi and goldfish. The moving, bubbling water is cooler and loaded with oxygen, making it easier for your fish to breathe.
  • Add Plants: Just as you seek out shady spots to shield yourself from the sun’s rays, fish will do the same to keep themselves cool. Make sure that about 60 percent of your pond’s surface is covered with floating plants, water lilies and other types of shade cover for your pond pets.
  • Add Water: Warmer temperatures mean increased evaporation rates, so make sure you top off your pond during hot weather. Doing so isn’t a substitute for a water change, but it will cool off the water and ensure your finned friends have enough wet stuff in their pond.

One last tip: Do not feed your fish when water temperatures are above 85°F. They probably won’t be hungry. And besides, the uneaten food will just ruin your water quality.

Do I Need Aeration in the Hot Summer Months? – Pond & Lake Q & A

Q: Do I need aeration in the hot summer months?
– Several Customers

A: We are just starting to enter into the hottest days of summer. Are you and your pond prepared to deal with the scorching heat? The need for aeration in your pond during these temperatures is far greater than any other part of the year. Although most pond owners are aware of this fact, few know the true reasons behind the need.

The Need For Aeration
First, let’s start with the actual need for aeration in your pond. Every pond is a “time bomb” just waiting to go off. A pond that has just been excavated is usually nutrient free, making it easy to take care of. This stage in a ponds life is called Stage 1, and may only last one year depending on nutrient inputs. Man-made ponds and lakes tend to gain large amounts of nutrients in a short period of time, often after only a couple years of existence. When a pond enters this period of excess nutrients, it is called Stage 2. Once a pond enters this stage, you will begin to experience large amounts of algae and weed growth. Also during this stage the pond will develop a large buildup of organic debris at the bottom of the pond called “muck”. The “muck” in your pond will slowly decompose and release nutrients into the water column. These excess nutrients will cause more weed and algae growth. Along with the nutrient spike, the water body will also experience a rise in toxic gas levels. Also, when organic material decomposes, it uses oxygen in the water, causing dangerously low oxygen levels in the depths of your pond. Because ponds without aeration normally become thermally stratified, the toxic gasses created on the bottom buildup in the cool water underneath. A change in temperature, a heavy rain, or sometimes even high winds can turn the water over allowing the toxic, oxygen-deprived water at the bottom to mix into the top layer leaving your fish without oxygen and causing a fish kill.

Fountains vs. Bottom Bubblers
Many pond owners will turn to fountain aeration or surface aerators to experience some form of aesthetics for their dollar. While fountains are aesthetically pleasing, they will only draw surface waters. This leaves the bottom of the pond uncirculated and does nothing to eliminate toxic gases underneath. A better alternative is to consider a bottom bubbler. The bottom bubbler will circulate the entire water column, and eliminating the thermocline. This allows the organisms present to utilize the entire pond, not just the upper layer. The best option for a bottom bubbler is the Airmax® Aeration System . In combination with aerobic, “muck” eating bacteria (such as MuckAway™ Natural Bacteria), the system can eliminate up to 5 inches of “muck” per year.

How Airmax® Aeration Works
The system consists of a high quality air compressor which is mounted in a cabinet housing unit. The compressor pumps air through a lead free self-weighted air hose and out of the diffuser plate on the pond bottom. The diffuser assembly comes with air stones that inject oxygen into the pond directly and create a column of medium bubbles lift and circulate the entire water body. This keeps the oxygen levels even throughout the pond or lake. Something that is important to keep in mind is how to run the compressor. The aerator is as simple to run as plugging in the cord, and to reduce stress on organisms in the pond you should follow this start-up procedure.

Starting Up Your Airmax® Aeration System
When an aerator is first installed it is important that you don’t begin running it constantly right away. If the aerator rotates the water column too quickly, it can actually cause a fish kill by moving the toxic gases throughout the pond in one fell swoop. The best route to take is to run the aerator for only 30 minutes on its first day, then shutting it off for the remainder of that day. The second day you should run the aeration system for one full hour then turn it off. The third day double to 2 hours, then to 4 hours the next, 8 the next, until you are running your system all day. This process will take 7 days to accomplish. Not only should this process be followed the first time an aerator is installed, it should be followed every time the aerator is turned on after an extended shutdown.

Relax…
Now that we’ve covered the different needs and phases of pond aeration, lose the headache, and relax in the heat knowing you’re on your way to a healthy pond ecosystem.
