Use Aeration to Prevent Winter Fish Kills

Written by Industry Expert Joe Holz, International Sales Manager at Kasco Marine

Winter fish kills are a serious threat to your fish population if you live in the north. If large amounts of snow and ice form on your pond or lake, it can block out sunlight from penetrating into the water. Without sunlight, plants die, thus ceasing to give off oxygen they would produce during photosynthesis. The dead plant material also provides added nourishment for bacteria which also use oxygen. As the winter progresses, the available oxygen in the pond can be used up to a point where fish can suffer.

In the winter, the metabolism of fish will slow down. They move less, eat less, grow less, and use less oxygen. The same goes for bacteria in the pond, the oxygen consumption is lower. However, oxygen levels can drop low enough to cause major problems in a pond if the winter is severe enough. In many cases, the larger trophy fish of a given species will consume more oxygen. Therefore, during low oxygen times, your biggest fish can die.

Luckily, winterkill can be prevented.

Winter Fountain Maintenance: Time for an Oil & Seals Change?

by: SOLitude Lake Management   |   Oct 09, 2018

Warwickresort.winterpond.newportnewsVA_DaveR_1.18.15_eYour floating fountain helps to maintain the balance of your pond or lake with constant aeration while providing a pleasing view throughout summer months. As we head into winter, now is the best time to consider scheduling critical maintenance and “TLC” for your fountain, such as an oil and seals maintenance service.

This important fountain maintenance task will ensure that your seals are working as designed, preventing any water from leaking into the unit, and that that your pond fountain is running with clean oil. The oil and seals service includes performing an internal inspection of the power unit (motor and related parts), making any necessary adjustments, replacing any worn parts, and changing the oil, rotary shaft seal, and all related parts. Changing the oil in your fountain works much like changing the oil in your car: the cleaner the oil, the smoother it runs.

Breaking Through the Thermocline to Prevent Fish Kills

Submersed Aeration

Written by Industry Expert Cory Smith, Aquatic Specialist & Regional Leader

The long, warm days of summer provide the perfect backdrop for swimming, boating and fishing, but the last thing you want to encounter at your lake or pond is a summer fish kill. Fish kills are often a natural occurrence that can happen any time of year. However, they are especially common in the summer. As the weather changes, the surface and bottom of the waterbody form distinct layers containing different dissolved oxygen levels and temperatures.

Solar Aeration System: Aerate Your Pond Without Electricity

Solar Aeration

Written by Industry Expert Hunter Poland, Environmental Scientist

It’s not hard to identify a stagnant lake or pond. Typically, a waterbody lacking proper water circulation is characterized by foul odors, cloudy or scummy water, nuisance aquatic weeds and algae, and, in many cases, a plethora of mosquitoes. Fortunately, it is possible to reverse the problems that can result from stagnant water by installing a lake or pond aeration system. Traditional electric aeration systems can be effective when a power source is available near the pond, but in many situations, electric service is unavailable. Or, you may simply be interested in a more ecologically-friendly aeration solution. If so, a solar pond aerator may be a great option to improve circulation in your waterbody.

Use Aeration to Protect Your Fish This Winter

Frozen Pond

Written by Industry Expert Joe Holz, International Sales Manager at Kasco Marine

As we continue through the cold, winter months, protecting your fish should be on your top priority list. Many pond owners understand the need to have good oxygen levels to maintain a healthy, thriving fish population, however, most only think about oxygen levels during warm, summer months. Winter oxygen levels in areas that ice over can be just as, or even more, critical than during warmer times of the year. Low oxygen levels and the buildup of harmful gases over the winter can create dangerous conditions for fish in your pond.

The Nuts and Bolts—and Bubbles—of Lake and Pond Aeration

AS SEEN IN CAI ROCKY MOUNTAIN: Written by Industry Expert Shannon Junior, Aquatic Ecologist and Senior Business Development Consultant

CAI Rocky MountainThere are few events that can occur in a community pond that cause the amount of anxiety and uproar among the residents as a fish kill. Sure, we get plenty of calls about lake and pond algae blooms and clogged fountains and excessive trash, but nothing creates the level of panic that ensues when there are dead fish floating on the surface of the water. Many residents become concerned that there may have been a toxic spill or illegal dumping incident, or they think that the landscaping company must have used something on the surrounding property that killed the fish. In reality though, most fish kills occur not because of a poisonous substance, but because of low dissolved oxygen conditions in the water.

The Importance of Properly-Sized Lake and Pond Aeration

by: SOLitude Lake Management   |   Sep 07, 2017

Written by Industry Expert Kyle Finerfrock, Environmental Scientist

AerationOne of the great tools in a lake or pond manager’s tool box is the use of floating and subsurface aeration systems in a waterbody. Aeration is the mixing of water in a lake or pond to increase exposure to the atmosphere and decrease harmful gases like hydrogen sulfide within the aquatic ecosystem. A healthy waterbody that is well aerated will have suitable oxygen levels from the bottom to the surface.

Now, you may be wondering: why is it important to increase the oxygen levels in my pond? The benefits of an oxygenated lake or pond are tremendous. Oxygenation can help limit nuisance vegetation and algae by facilitating the conversion of pond nutrients to forms that do not sustain algae growth. Improved oxygenation and water circulation can also help reduce the accumulation of sediment at the bottom of the waterbody, which is one of the most common signs of an aging pond. Organisms that thrive in low or zero oxygen (anoxic) conditions promote poor waterbody health. A lake or pond that has no aeration will likely have anoxic conditions at depths greater than 8 feet deep in the summer months. In this zone, anaerobic bacteria can produce ammonia and hydrogen sulfide, which can be toxic to other organisms and produce foul odors. Anoxic conditions can also change the chemistry of a lake or pond. For example, pond nutrients such as nitrogen and phosphorus promote nuisance algae growth and can become excessive when low oxygen conditions exist in the aquatic environment

The Importance of Lake and Pond Aeration Systems

by: SOLitude Lake Management   |   Jul 18, 2017

Written by Industry Expert Greg Blackham, Aquatic Specialist

Floating FountainChoosing the correct aeration delivery system for your lake or pond is one of the most important decisions you will make for the long-term health and balance of your waterbody. Regardless of how big or small your waterbody is, the goal of an aeration system is to evenly spread an adequate amount of dissolved oxygen throughout the entire water column. Lakes and ponds naturally receive dissolved oxygen from several sources, most notably plant respiration and atmospheric surface mixing. This input of oxygen should be equal to or greater than the demand of the aquatic ecosystem. The entire ecosystem of the water needs that dissolved oxygen, whether at the very bottom of the food chain for microbial decomposition, or at the top for largemouth bass and other predator fish. In most cases, it is discovered that the oxygen supply is lacking due to pond nutrient pollution or other stresses caused by people and land development.

To determine what type of oxygen delivery method or aeration system is appropriate, the waterbody needs to be looked at from several angles. Many online resources recommend aeration systems based on only one or two aspects of the waterbody. To find the best aeration solution, several factors should be considered: 1) overall acreage of the lake or pond, 2) average water depth, 3) maximum water depth, 4) shape of the waterbody, 5) proximity to electricity, 6) desired aesthetics, 7) noise tolerance, 8) water quality. The more information we have, the better we can determine how to spread the dissolved oxygen throughout the entire lake or pond.
