Pond Aerator for Fish Kill Prevention


Fish kill is a common occurrence in many northern states during the harsh, cold winters. 

As the temperature falls, ice can form across the entire pond and stay for months. 

This sets off a chain of events that can deplete oxygen levels and ultimately suffocate fish. Let’s dive into the science behind the reduction in dissolved oxygen levels and provide a simple solution to keep your fish alive and healthy.

Subsurface aeration: a quick and easy solution

Subsurface aeration – or bottom diffused aeration – is an energy efficient, quiet, and highly effective process of increasing dissolved oxygen levels and circulating water throughout the pond.

Creates an opening in the ice

One of the advantages of subsurface aeration in any season is that it mixes the pond from the bottom up – evenly distributing oxygen and helping the pond turn over.

As the pond turns over, water reaches the surface and absorbs oxygen. In the winter, water circulation helps create a hole in the ice. This allows for the deadly gases to escape, for sunlight to reach aquatic plants, and for water to reach the surface and receive oxygen from the atmosphere.

Adds dissolved oxygen

The tiny bubbles that are diffused with subsurface aeration infuse oxygen into the water column from the bottom up. This not only provides dissolved oxygen for fish, but it feeds aerobic (beneficial) bacteria, which can continue to consume the organic matter throughout winter. This should make for less cleanup and a clearer pond in the spring.

Why Aeration is Essential to a Healthy Aquaponics System


"Quality air pumps are an irreplaceable component of aquaponic systems, and many systems have been saved from catastrophic collapse because of an abundance of DO." ~Food and Agriculture Organization of the United Nations

What is aquaponics?


Aquaponics combines aquaculture (raising fish in tanks) and hydroponics (growing vegetables/ plants in water with a soil-less media).

This balanced, self-contained, and natural process mimics the ecosystems of rivers, lakes, ponds, and waterways on the planet yielding 100% organic fish and vegetables.

How does it work?


The three living components that drive the closed loop system are fish, beneficial bacteria, and plants - the only outside input is fish food. Fish naturally excrete urine and feces into the tank, and their waste is high in ammonium and can become highly toxic.  

Therefore, the water in the tank is pumped to a biofilter, which is loaded with beneficial bacteria. The beneficial bacteria – which are fed by oxygen from an air pump – breaks down the ammonia into nitrates. The water is then pumped to soil-less media bed (hydroponics) where the nitrates act as a fertilizer to the plants. The plants remove the nitrates from the water (purifying it), and the clean water then returns to the fish tank to complete the loop.

Simply put, without proper dissolved oxygen levels, aquaponics would fail.  Fish require oxygen to survive, grow, and multiply.  Beneficial (Aerobic) bacteria need oxygen to live and multiply in the biofilter.  Without the bacteria, the fish wouldn’t absorb the fertilizer needed to grow.  Therefore, a reliable air pump is essential and a quality diffuser is important.  

Professionals recommend a “fine bubble” diffuser which creates more bubbles and thus more surface area on the bubbles for oxygen to transfer into the water. It’s imperative to check the diffusers regularly, so they don’t clog.

Sustainable Farming with Aquaponics


Aquaponics combines aquaculture (raising fish in tanks) and hydroponics (growing vegetables/ plants in water with a soil-less media).

This balanced, self-contained, and natural process mimics the ecosystems of rivers, lakes, ponds, and waterways on the planet yielding 100% organic fish and vegetables.

What are the benefits of aquaponics?


  • Since aquaponic systems can be installed indoors, food can be produced anywhere and throughout the entire year
  • The biological cycle is 100% chemical-free and does not require pesticides or herbicides  
  • Since aquaponics is a closed loop system, it uses ~90-95% less water than traditional farming methods
  • The food produced has more nutrients and generally is thought to taste better
  • Vegetables tend to grow 3x faster because of their exposure to 100% natural nutrients, 24 hours a day
  • Food independence

Fall Pond Aeration


At HIBLOW USA we receive many calls each year at the end of summer asking if pond aeration is needed in the fall, or if they should turn off our pump and store it until spring.  They also ask if the pump can handle colder temperatures.  The answer is yes to both.  Many argue that fall is the most important time of the year to run the pond aerator.  Sudden drops in temperature, a reduction in sunlight, strong storms, and an increase of organic debris all contribute to reduction in oxygen levels that directly impact the health of the pond.

Reduction in oxygen from plants


Aquatic plants, due to photosynthesis, create oxygen for ponds.  Naturally, as the cold sets in and there is less sunlight, algae and other aquatic plants start to die off or go dormant.  The green plants that survive produce much less oxygen because of the reduction in sunlight.  

Increase in organic matter


Organic debris is most prevalent in the fall.  As leaves change color and drop to the ground, they and other dying aquatic vegetation are swept into the pond.  Fertilizer and decaying insects/ animals also find their way into the water, further impacting the water composition.  Nature uses beneficial micro-organisms (aerobic bacteria) – which require oxygen to live and thrive – to decompose organic matter.  With the influx of debris in the pond, more oxygen is needed to speed up the decomposition.  If there is not sufficient oxygen, the organic matter will be slow to decompose and can build up at the bottom of the pond.  Not only will this make for a major spring cleanup, the condition can contribute to fish kill in the winter.

SepticSmart Week Starts on September 20!


Is your septic system being maintained properly?

Do you worry about it failing or your home flooding?

SepticSmart Week starts next week, and this is the perfect opportunity to make sure you’re doing everything you can to properly maintain your septic system.

According to the EPA, “most septic systems fail because of inappropriate design or poor maintenance. Some soil-based systems (those with a drain field) are installed at sites with inadequate or inappropriate soils, excessive slopes, or high ground water tables. These conditions can cause hydraulic failures and contamination of nearby water sources.”

Failure to keep up with routine maintenance, either on your own or by hiring a professional, could cause solids in the tank to migrate into the drain field and clog your system.

How can you make sure you avoid any issues? Read the full article about SepticSmart week on our website!
